Complete Parameter List


This is a complete list of the parameters which can be set via the MAVLink protocol in the EEPROM of your autopilot to control vehicle behaviour. This list is automatically generated from the latest ardupilot source code, and so may contain parameters which are not yet in the stable released versions of the code.

AMSL limit (AFS_AMSL_LIMIT)

Note: This parameter is for advanced users

This sets the AMSL (above mean sea level) altitude limit. If the pressure altitude determined by QNH exceeds this limit then flight termination will be forced. Note that this limit is in meters, whereas pressure altitude limits are often quoted in feet. A value of zero disables the pressure altitude limit.

Error margin for GPS based AMSL limit (AFS_AMSL_ERR_GPS)

Note: This parameter is for advanced users

This sets margin for error in GPS derived altitude limit. This error margin is only used if the barometer has failed. If the barometer fails then the GPS will be used to enforce the AMSL_LIMIT, but this margin will be subtracted from the AMSL_LIMIT first, to ensure that even with the given amount of GPS altitude error the pressure altitude is not breached. OBC users should set this to comply with their D2 safety case. A value of -1 will mean that barometer failure will lead to immediate termination.

QNH pressure (AFS_QNH_PRESSURE)

Enable dual loss terminate due to failure of both GCS and GPS simultaneously (AFS_DUAL_LOSS)

Note: This parameter is for advanced users

This enables the dual loss termination part of the AFS system. If this parameter is 1 and both GPS and the ground control station fail simultaneously, this will be considered a "dual loss" and cause termination.

RC failure time (AFS_RC_FAIL_TIME)

Note: This parameter is for advanced users

This is the time in seconds in manual mode that failsafe termination will activate if RC input is lost. For the OBC rules this should be (1.5). Use 0 to disable.

AHRS_ Parameters

AHRS GPS gain (AHRS_GPS_GAIN)

Note: This parameter is for advanced users

This controls how much to use the GPS to correct the attitude. This should never be set to zero for a plane as it would result in the plane losing control in turns. For a plane please use the default value of 1.0.

AHRS use GPS for DCM navigation and position-down (AHRS_GPS_USE)

Note: This parameter is for advanced users

This controls whether to use dead-reckoning or GPS based navigation. If set to 0 then the GPS won't be used for navigation, and only dead reckoning will be used. A value of zero should never be used for normal flight. Currently this affects only the DCM-based AHRS: the EKF uses GPS according to its own parameters. A value of 2 means to use GPS for height as well as position - both in DCM estimation and when determining altitude-above-home.

Yaw P (AHRS_YAW_P)

Note: This parameter is for advanced users

This controls the weight the compass or GPS has on the heading. A higher value means the heading will track the yaw source (GPS or compass) more rapidly.

AHRS RP_P (AHRS_RP_P)

Note: This parameter is for advanced users

This controls how fast the accelerometers correct the attitude

Maximum wind (AHRS_WIND_MAX)

Note: This parameter is for advanced users

This sets the maximum allowable difference between ground speed and airspeed. A value of zero means to use the airspeed as is. This allows the plane to cope with a failing airspeed sensor by clipping it to groundspeed plus/minus this limit. See ARSPD_OPTIONS and ARSPD_WIND_MAX to disable airspeed sensors.

AHRS Trim Roll (AHRS_TRIM_X)

Compensates for the roll angle difference between the control board and the frame. Positive values make the vehicle roll right.

AHRS Trim Pitch (AHRS_TRIM_Y)

Compensates for the pitch angle difference between the control board and the frame. Positive values make the vehicle pitch up/back.

AHRS Trim Yaw (AHRS_TRIM_Z)

Note: This parameter is for advanced users

Not Used

Board Orientation (AHRS_ORIENTATION)

Note: This parameter is for advanced users

Overall board orientation relative to the standard orientation for the board type. This rotates the IMU and compass readings to allow the board to be oriented in your vehicle at any 90 or 45 degree angle. The label for each option is specified in the order of rotations for that orientation. This option takes affect on next boot. After changing you will need to re-level your vehicle. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the AHRS_CUSTOM_ROLL/PIT/YAW angles for AHRS orientation. Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_ROT1_ROLL/PIT/YAW or CUST_ROT2_ROLL/PIT/YAW angles.

AHRS Velocity Complementary Filter Beta Coefficient (AHRS_COMP_BETA)

Note: This parameter is for advanced users

This controls the time constant for the cross-over frequency used to fuse AHRS (airspeed and heading) and GPS data to estimate ground velocity. Time constant is 0.1/beta. A larger time constant will use GPS data less and a small time constant will use air data less.

AHRS GPS Minimum satellites (AHRS_GPS_MINSATS)

Note: This parameter is for advanced users

The orientation of the first external compass relative to the vehicle frame. This value will be ignored unless this compass is set as an external compass. When set correctly in the northern hemisphere, pointing the nose and right side down should increase the MagX and MagY values respectively. Rolling the vehicle upside down should decrease the MagZ value. For southern hemisphere, switch increase and decrease. NOTE: For internal compasses, AHRS_ORIENT is used. The label for each option is specified in the order of rotations for that orientation. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the COMPASS_CUS_ROLL/PIT/YAW angles for Compass orientation. Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_1_ROLL/PIT/YAW or CUST_2_ROLL/PIT/YAW angles.

Compass is attached via an external cable (COMPASS_EXTERNAL)

Note: This parameter is for advanced users

Configure compass so it is attached externally. This is auto-detected on most boards. Set to 1 if the compass is externally connected.

Note: This parameter is for advanced users

This is the RMS value of noise in magnetometer measurements. Increasing it reduces the weighting on these measurements.

Magnetometer default fusion mode (EK2_MAG_CAL)

Note: This parameter is for advanced users

This determines when the filter will use the 3-axis magnetometer fusion model that estimates both earth and body fixed magnetic field states, when it will use a simpler magnetic heading fusion model that does not use magnetic field states and when it will use an alternative method of yaw determination to the magnetometer. The 3-axis magnetometer fusion is only suitable for use when the external magnetic field environment is stable. EK2_MAG_CAL = 0 uses heading fusion on ground, 3-axis fusion in-flight, and is the default setting for Plane users. EK2_MAG_CAL = 1 uses 3-axis fusion only when manoeuvring. EK2_MAG_CAL = 2 uses heading fusion at all times, is recommended if the external magnetic field is varying and is the default for rovers. EK2_MAG_CAL = 3 uses heading fusion on the ground and 3-axis fusion after the first in-air field and yaw reset has completed, and is the default for copters. EK2_MAG_CAL = 4 uses 3-axis fusion at all times. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK2_MAG_MASK parameter. NOTE: limited operation without a magnetometer or any other yaw sensor is possible by setting all COMPASS_USE, COMPASS_USE2, COMPASS_USE3, etc parameters to 0 with COMPASS_ENABLE set to 1. If this is done, the EK2_GSF_RUN and EK2_GSF_USE masks must be set to the same as EK2_IMU_MASK.

Note: This parameter is for advanced users

This is the RMS value of noise in equivalent airspeed measurements used by planes. Increasing it reduces the weighting of airspeed measurements and will make wind speed estimates less noisy and slower to converge. Increasing also increases navigation errors when dead-reckoning without GPS measurements.

Airspeed measurement gate size (EK2_EAS_I_GATE)

Note: This parameter is for advanced users

This sets the percentage number of standard deviations applied to the airspeed measurement innovation consistency check. Decreasing it makes it more likely that good measurements will be rejected. Increasing it makes it more likely that bad measurements will be accepted.

Note: This parameter is for advanced users

Range finder can be used as the primary height source when below this percentage of its maximum range (see RNGFND*_MAX). This will not work unless Baro or GPS height is selected as the primary height source vis EK2_ALT_SOURCE = 0 or 2 respectively. This feature should not be used for terrain following as it is designed for vertical takeoff and landing with climb above the range finder use height before commencing the mission, and with horizontal position changes below that height being limited to a flat region around the takeoff and landing point.

Note: This parameter is for advanced users

When a height sensor other than GPS is used as the primary height source by the EKF, the position of the zero height datum is defined by that sensor and its frame of reference. If a GPS height measurement is also available, then the height of the WGS-84 height datum used by the EKF can be corrected so that the height returned by the getLLH() function is compensated for primary height sensor drift and change in datum over time. The first two bit positions control when the height datum will be corrected. Correction is performed using a Bayes filter and only operates when GPS quality permits.

This estimator uses IMU, GPS and, if available, airspeed data. EKF-GSF yaw estimator data for the primary EKF2 instance will be logged as GSF0 and GSF1 messages. Use of the yaw estimate generated by this algorithm is controlled by the EK2_GSF_USE_MASK and EK2_GSF_RST_MAX parameters.

EK3_ Parameters

Enable EKF3 (EK3_ENABLE)

Note: This parameter is for advanced users

This enables EKF3. Enabling EKF3 only makes the maths run, it does not mean it will be used for flight control. To use it for flight control set AHRS_EKF_TYPE=3. A reboot or restart will need to be performed after changing the value of EK3_ENABLE for it to take effect.

GPS horizontal velocity measurement noise (m/s) (EK3_VELNE_M_NSE)

Note: This parameter is for advanced users

Note: This parameter is for advanced users

This sets a lower limit on the speed accuracy reported by the GPS receiver that is used to set vertical velocity observation noise.

Note: This parameter is for advanced users

This sets the percentage number of standard deviations applied to the GPS velocity measurement innovation consistency check. Decreasing it makes it more likely that good measurements will be rejected. Increasing it makes it more likely that bad measurements will be accepted. If EK3_GLITCH_RAD set to 0 the velocity innovations will be clipped instead of rejected if they exceed the gate size and a smaller value of EK3_VEL_I_GATE not exceeding 300 is recommended to limit the effect of GPS transient errors.

GPS horizontal position measurement noise (m) (EK3_POSNE_M_NSE)

Note: This parameter is for advanced users

This sets the GPS horizontal position observation noise. Increasing it reduces the weighting of GPS horizontal position measurements.

GPS position measurement gate size (EK3_POS_I_GATE)

Note: This parameter is for advanced users

This sets the percentage number of standard deviations applied to the GPS position measurement innovation consistency check. Decreasing it makes it more likely that good measurements will be rejected. Increasing it makes it more likely that bad measurements will be accepted. If EK3_GLITCH_RAD has been set to 0 the horizontal position innovations will be clipped instead of rejected if they exceed the gate size so a smaller value of EK3_POS_I_GATE not exceeding 300 is recommended to limit the effect of GPS transient errors.

GPS glitch radius gate size (m) (EK3_GLITCH_RAD)

Note: This parameter is for advanced users

This controls the maximum radial uncertainty in position between the value predicted by the filter and the value measured by the GPS before the filter position and velocity states are reset to the GPS. Making this value larger allows the filter to ignore larger GPS glitches but also means that non-GPS errors such as IMU and compass can create a larger error in position before the filter is forced back to the GPS position. If EK3_GLITCH_RAD set to 0 the GPS innovations will be clipped instead of rejected if they exceed the gate size set by EK3_VEL_I_GATE and EK3_POS_I_GATE which can be useful if poor quality sensor data is causing GPS rejection and loss of navigation but does make the EKF more susceptible to GPS glitches. If setting EK3_GLITCH_RAD to 0 it is recommended to reduce EK3_VEL_I_GATE and EK3_POS_I_GATE to 300.

Altitude measurement noise (m) (EK3_ALT_M_NSE)

Note: This parameter is for advanced users

This is the RMS value of noise in the altitude measurement. Increasing it reduces the weighting of the baro measurement and will make the filter respond more slowly to baro measurement errors, but will make it more sensitive to GPS and accelerometer errors. A larger value for EK3_ALT_M_NSE may be required when operating with EK3_SRCx_POSZ = 0. This parameter also sets the noise for the 'synthetic' zero height measurement that is used when EK3_SRCx_POSZ = 0.

Height measurement gate size (EK3_HGT_I_GATE)

Note: This parameter is for advanced users

This sets the percentage number of standard deviations applied to the height measurement innovation consistency check. Decreasing it makes it more likely that good measurements will be rejected. Increasing it makes it more likely that bad measurements will be accepted. If EK3_GLITCH_RAD set to 0 the vertical position innovations will be clipped instead of rejected if they exceed the gate size and a smaller value of EK3_HGT_I_GATE not exceeding 300 is recommended to limit the effect of height sensor transient errors.

Note: This parameter is for advanced users

This is the RMS value of noise in magnetometer measurements. Increasing it reduces the weighting on these measurements.

Magnetometer default fusion mode (EK3_MAG_CAL)

Note: This parameter is for advanced users

This determines when the filter will use the 3-axis magnetometer fusion model that estimates both earth and body fixed magnetic field states and when it will use a simpler magnetic heading fusion model that does not use magnetic field states. The 3-axis magnetometer fusion is only suitable for use when the external magnetic field environment is stable. EK3_MAG_CAL = 0 uses heading fusion on ground, 3-axis fusion in-flight, and is the default setting for Plane users. EK3_MAG_CAL = 1 uses 3-axis fusion only when manoeuvring. EK3_MAG_CAL = 2 uses heading fusion at all times, is recommended if the external magnetic field is varying and is the default for rovers. EK3_MAG_CAL = 3 uses heading fusion on the ground and 3-axis fusion after the first in-air field and yaw reset has completed, and is the default for copters. EK3_MAG_CAL = 4 uses 3-axis fusion at all times. EK3_MAG_CAL = 5 uses an external yaw sensor with simple heading fusion. NOTE : Use of simple heading magnetometer fusion makes vehicle compass calibration and alignment errors harder for the EKF to detect which reduces the sensitivity of the Copter EKF failsafe algorithm. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK3_MAG_MASK parameter. EK3_MAG_CAL = 6 uses an external yaw sensor with fallback to compass when the external sensor is not available if we are flying. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK3_MAG_MASK parameter. NOTE: limited operation without a magnetometer or any other yaw sensor is possible by setting all COMPASS_USE, COMPASS_USE2, COMPASS_USE3, etc parameters to 0 and setting COMPASS_ENABLE to 0. If this is done, the EK3_GSF_RUN and EK3_GSF_USE masks must be set to the same as EK3_IMU_MASK. A yaw angle derived from IMU and GPS velocity data using a Gaussian Sum Filter (GSF) will then be used to align the yaw when flight commences and there is sufficient movement.

Note: This parameter is for advanced users

1 byte bitmap of IMUs to use in EKF3. A separate instance of EKF3 will be started for each IMU selected. Set to 1 to use the first IMU only (default), set to 2 to use the second IMU only, set to 3 to use the first and second IMU. Additional IMU's can be used up to a maximum of 6 if memory and processing resources permit. There may be insufficient memory and processing resources to run multiple instances. If this occurs EKF3 will fail to start.

GPS accuracy check scaler (%) (EK3_CHECK_SCALE)

Note: This parameter is for advanced users

This scales the thresholds that are used to check GPS accuracy before it is used by the EKF. A value of 100 is the default. Values greater than 100 increase and values less than 100 reduce the maximum GPS error the EKF will accept. A value of 200 will double the allowable GPS error.

Note: This parameter is for advanced users

This sets the amount of position variation that the EKF allows for when operating without external measurements (eg GPS or optical flow). Increasing this parameter makes the EKF attitude estimate less sensitive to vehicle manoeuvres but more sensitive to IMU errors.

Bitmask controlling sidelip angle fusion (EK3_BETA_MASK)

Note: This parameter is for advanced users

1 byte bitmap controlling use of sideslip angle fusion for estimation of non wind states during operation of 'fly forward' vehicle types such as fixed wing planes. By assuming that the angle of sideslip is small, the wind velocity state estimates are corrected whenever the EKF is not dead reckoning (e.g. has an independent velocity or position sensor such as GPS). This behaviour is on by default and cannot be disabled. When the EKF is dead reckoning, the wind states are used as a reference, enabling use of the small angle of sideslip assumption to correct non wind velocity states (eg attitude, velocity, position, etc) and improve navigation accuracy. This behaviour is on by default and cannot be disabled. The behaviour controlled by this parameter is the use of the small angle of sideslip assumption to correct non wind velocity states when the EKF is NOT dead reckoning. This is primarily of benefit to reduce the buildup of yaw angle errors during straight and level flight without a yaw sensor (e.g. magnetometer or dual antenna GPS yaw) provided aerobatic flight maneuvers with large sideslip angles are not performed. The 'always' option might be used where the yaw sensor is intentionally not fitted or disabled. The 'WhenNoYawSensor' option might be used if a yaw sensor is fitted, but protection against in-flight failure and continual rejection by the EKF is desired. For vehicles operated within visual range of the operator performing frequent turning maneuvers, setting this parameter is unnecessary.

NOTE : Use of a different magnetometer fusion algorithm on different cores makes unwanted EKF core switches due to magnetometer errors more likely.

When a height sensor other than GPS is used as the primary height source by the EKF, the position of the zero height datum is defined by that sensor and its frame of reference.

Ratio of mass to drag coefficient measured along the Y body axis. This parameter enables estimation of wind drift for vehicles with bluff bodies and without propulsion forces in the X and Y direction (eg multicopters). The drag produced by this effect scales with speed squared. Set to a positive value > 1.0 to enable. A starting value is the mass in Kg divided by the side area. The predicted drag from the rotors is specified separately by the EK3_DRAG_MCOEF parameter.

Observation noise for drag acceleration (EK3_DRAG_M_NSE)

Note: This parameter is for advanced users

This sets the amount of noise used when fusing X and Y acceleration as an observation that enables estimation of wind velocity for multi-rotor vehicles. This feature is enabled by the EK3_DRAG_BCOEF_X and EK3_DRAG_BCOEF_Y parameters

Momentum coefficient for propeller drag (EK3_DRAG_MCOEF)

Note: This parameter is for advanced users

This parameter is used to predict the drag produced by the rotors when flying a multi-copter, enabling estimation of wind drift. The drag produced by this effect scales with speed not speed squared and is produced because some of the air velocity normal to the rotors axis of rotation is lost when passing through the rotor disc which changes the momentum of the airflow causing drag. For unducted rotors the effect is roughly proportional to the area of the propeller blades when viewed side on and changes with different propellers. It is higher for ducted rotors. For example if flying at 15 m/s at sea level conditions produces a rotor induced drag acceleration of 1.5 m/s/s, then EK3_DRAG_MCOEF would be set to 0.1 = (1.5/15.0). Set EK3_MCOEF to a positive value to enable wind estimation using this drag effect. To account for the drag produced by the body which scales with speed squared, see documentation for the EK3_DRAG_BCOEF_X and EK3_DRAG_BCOEF_Y parameters.

Bit 0 (JammingExpected): Setting JammingExpected will change the EKF behaviour such that if dead reckoning navigation is possible it will require the preflight alignment GPS quality checks controlled by EK3_GPS_CHECK and EK3_CHECK_SCALE to pass before resuming GPS use if GPS lock is lost for more than 2 seconds to prevent bad position estimate. Bit 1 (Manual lane switching): DANGEROUS – If enabled, this disables automatic lane switching. If the active lane becomes unhealthy, no automatic switching will occur. Users must manually set EK3_PRIMARY to change lanes. No health checks will be performed on the selected lane. Use with extreme caution.

Note: This parameter is for advanced users

The FFT harmonic peak target that should be returned by FTN1.PkAvg. The resulting value will be used by the harmonic notch if configured to track the FFT frequency.

Setting this to 1 will always target the highest energy peak. Setting this to 2 will target the highest energy peak that is lower in frequency than the highest energy peak. Setting this to 3 will target the highest energy peak that is higher in frequency than the highest energy peak.

H_ Parameters

Tail Type (H_TAIL_TYPE)

Tail type selection. Servo Only uses tail rotor pitch to provide yaw control (including stabilization) via an output assigned to Motor4. Servo with External Gyro uses an external gyro to control tail rotor pitch via a servo. Yaw control without stabilization is passed to the external gyro via the output assigned to Motor4. Direct Drive Variable Pitch(DDVP) is used for tails that have a motor whose ESC is connected to an output with function HeliTailRSC. Tail pitch is still accomplished with a servo on an output assigned to Motor4 function. Direct Drive Fixed Pitch (DDFP) CW is used for helicopters with a rotor that spins clockwise when viewed from above with a motor whose ESC is controlled by an output whose function is Motor4. Direct Drive Fixed Pitch (DDFP) CCW is used for helicopters with a rotor that spins counter clockwise when viewed from above with a motor whose ESC is controlled by an output whose function is Motor4. In both DDFP cases, no servo is used for the tail and the tail motor esc on Motor4 output is used to control the yaw axis using motor speed.

Heli_Options (H_OPTIONS)

Bitmask of heli options. Bit 0 changes how the pitch, roll, and yaw axis integrator term is managed for low speed and takeoff/landing. In AC 4.0 and earlier, scheme uses a leaky integrator for ground speeds less than 5 m/s and won't let the steady state integrator build above ILMI.

H_RSC_ Parameters

External Motor Governor Setpoint (H_RSC_SETPOINT)

Throttle (HeliRSC Servo) output in percent to the external motor governor when motor interlock enabled (throttle hold off).

Rotor Speed Control Mode (H_RSC_MODE)

Selects the type of rotor speed control used to determine throttle output to the HeliRSC servo channel when motor interlock is enabled (throttle hold off). RC Passthrough sends the input from the RC Motor Interlock channel as throttle output. External Gov SetPoint sends the RSC SetPoint parameter value as throttle output. Throttle Curve uses the 5 point throttle curve to determine throttle output based on the collective output. AutoThrottle requires a rotor speed sensor, contains an advanced autothrottle governor and is primarily for piston and turbine engines. WARNING: Throttle ramp time and throttle curve MUST be tuned properly using Throttle Curve mode before using AutoThrottle

Throttle Ramp Time (H_RSC_RAMP_TIME)

Time in seconds for throttle output (HeliRSC servo) to ramp from ground idle (RSC_IDLE) to flight idle throttle setting when motor interlock is enabled (throttle hold off).

Rotor Runup Time (H_RSC_RUNUP_TIME)

Actual time in seconds for the main rotor to reach full speed after motor interlock is enabled (throttle hold off). Must be at least one second longer than the Throttle Ramp Time that is set with RSC_RAMP_TIME. WARNING: For AutoThrottle users with piston and turbine engines it is VERY important to know how long it takes to warm up your engine and reach full rotor speed when throttle switch is turned ON. This timer should be set for at least the amount of time it takes to get your helicopter to full flight power, ready for takeoff. Failure to heed this warning could result in the auto-takeoff mode attempting to lift up into hover before the engine has reached full power, and subsequent loss of control

Critical Rotor Speed (H_RSC_CRITICAL)

Percentage of normal rotor speed where flight is no longer possible. However currently the rotor runup/rundown is estimated using the RSC_RUNUP_TIME parameter. Estimated rotor speed increases/decreases between 0 (rotor stopped) to 1 (rotor at normal speed) in the RSC_RUNUP_TIME in seconds. This parameter should be set so that the estimated rotor speed goes below critical in approximately 3 seconds. So if you had a 10 second runup time then set RSC_CRITICAL to 70%.

Throttle Output at Idle (H_RSC_IDLE)

Throttle output (HeliRSC Servo) in percent while armed but motor interlock is disabled (throttle hold on). FOR COMBUSTION ENGINES. Sets the engine ground idle throttle percentage with clutch disengaged. This must be set to zero for electric helicopters under most situations. If the ESC has an autorotation window this can be set to keep the autorotation window open in the ESC. Consult the operating manual for your ESC to set it properly for this purpose

Throttle Slew Rate (H_RSC_SLEWRATE)

This controls the maximum rate at which the throttle output (HeliRSC servo) can change, as a percentage per second. A value of 100 means the throttle can change over its full range in one second. A value of zero gives unlimited slew rate.

Throttle Curve at 0% Coll (H_RSC_THRCRV_0)

Sets the throttle output (HeliRSC servo) in percent for the throttle curve at the minimum collective pitch position. The 0 percent collective is defined by H_COL_MIN. Example: if the setup has -2 degree to +10 degree collective pitch setup, this setting would correspond to -2 degree of pitch.

Throttle Curve at 25% Coll (H_RSC_THRCRV_25)

Sets the throttle output (HeliRSC servo) in percent for the throttle curve at 25% of full collective travel where he 0 percent collective is defined by H_COL_MIN and 100 percent collective is defined by H_COL_MAX. Example: if the setup has -2 degree to +10 degree collective pitch setup, the total range is 12 degrees. 25% of 12 degrees is 3 degrees, so this setting would correspond to +1 degree of pitch.

Throttle Curve at 50% Coll (H_RSC_THRCRV_50)

Sets the throttle output (HeliRSC servo) in percent for the throttle curve at 50% of full collective travel where he 0 percent collective is defined by H_COL_MIN and 100 percent collective is defined by H_COL_MAX. Example: if the setup has -2 degree to +10 degree collective pitch setup, the total range is 12 degrees. 50% of 12 degrees is 6 degrees, so this setting would correspond to +4 degree of pitch.

Throttle Curve at 75% Coll (H_RSC_THRCRV_75)

Sets the throttle output (HeliRSC servo) in percent for the throttle curve at 75% of full collective travel where he 0 percent collective is defined by H_COL_MIN and 100 percent collective is defined by H_COL_MAX. Example: if the setup has -2 degree to +10 degree collective pitch setup, the total range is 12 degrees. 75% of 12 degrees is 9 degrees, so this setting would correspond to +7 degree of pitch.

Throttle Curve at 100% Coll (H_RSC_THRCRV_100)

Sets the throttle output (HeliRSC servo) in percent for the throttle curve at the minimum collective pitch position. The 100 percent collective is defined by H_COL_MAX. Example: if the setup has -2 degree to +10 degree collective pitch setup, this setting would correspond to +10 degree of pitch.

Governor Operational Range (H_RSC_GOV_RANGE)

RPM range +/- governor rpm reference setting where governor is operational. If speed sensor fails or rpm falls outside of this range, the governor will disengage and return to throttle curve. Recommended range is 100

Cooldown Time (H_RSC_CLDWN_TIME)

Will provide a fast idle for engine cooldown by raising the Ground Idle speed setting by 50% for the number of seconds the timer is set for. A setting of zero disables the fast idle. This feature will only apply after the runup complete has been declared. This will not extend the time before ground idle is declared, which triggers engine shutdown for autonomous landings.

Governor Torque Compensator (H_RSC_GOV_COMP)

Adjusts the autothrottle governor torque compensator that determines how fast the governor will adjust the base torque reference to compensate for changes in density altitude. If RPM is low or high by more than 2-5 RPM, increase this setting by 1% at a time until the governor speed matches your RPM setting. Setting the compensator too high can result in surging and throttle "hunting". Do not make large adjustments at one time

Governor Droop Compensator (H_RSC_GOV_DROOP)

AutoThrottle governor droop response under load, normal settings of 0-50%. Higher value is quicker response to large speed changes due to load but may cause surging. Adjust this to be as aggressive as possible without getting surging or RPM over-run when the governor responds to large load changes on the rotor system

Governor Feedforward (H_RSC_GOV_FF)

Feedforward governor gain to throttle response during sudden loading/unloading of the rotor system. If RPM drops excessively during full collective climb with the droop response set correctly, increase the governor feedforward.

Rotor RPM Setting (H_RSC_GOV_RPM)

Main rotor RPM that governor maintains when engaged

Governor Torque Limiter (H_RSC_GOV_TORQUE)

Adjusts the engine's percentage of torque rise on autothrottle during ramp-up to governor speed. The torque rise will determine how fast the rotor speed will ramp up when rotor speed reaches 50% of the rotor RPM setting. The sequence of events engaging the governor is as follows: Throttle ramp time will engage the clutch and start the main rotor turning. The collective should be at flat pitch and the throttle curve set to provide at least 50% of normal RPM at flat pitch. The autothrottle torque limiter will automatically activate and start accelerating the main rotor. If the autothrottle consistently fails to accelerate the main rotor during ramp-in due to engine tune or other factors, then increase the torque limiter setting. NOTE: throttle ramp time and throttle curve should be tuned using RSC_MODE Throttle Curve before using RSC_MODE AutoThrottle

H_RSC_AROT_ Parameters

Enable autorotation handling in RSC (H_RSC_AROT_ENBL)

Allows you to enable (1) or disable (0) the autorotation functionality within the Rotor Speed Controller.

Time for in-flight power re-engagement when exiting autorotations (H_RSC_AROT_RAMP)

When exiting an autorotation in a bailout manoeuvre, this is the time in seconds for the throttle output (HeliRSC servo) to ramp from idle (H_RSC_AROT_IDLE) to flight throttle setting when motor interlock is re-enabled. When using an ESC with an autorotation bailout function, this parameter should be set to 0.1 (minimum value).

Idle throttle percentage during autorotation (H_RSC_AROT_IDLE)

Idle throttle used for during autotoration. For external governors, this would be set to a value that is within the autorotation window of the governer/ESC to enable fast spool-up, when bailing out of an autorotation. Set 0 to disable.

Time allowed for in-flight power re-engagement (H_RSC_AROT_RUNUP)

When exiting an autorotation in a bailout manoeuvre, this is the expected time in seconds for the main rotor to reach full speed after motor interlock is enabled. Must be at least one second longer than the H_RSC_AROT_RAMP time that is set. This timer should be set for at least the amount of time it takes to get your helicopter to full flight power. Failure to heed this warning could result in early entry into autonomously controlled collective modes (e.g. alt hold, loiter, etc), whereby the collective could be raised before the engine has reached full power, with a subsequently dangerous slowing of head speed.

INS_HNTC2_ Parameters

Harmonic Notch Filter enable (INS_HNTC2_ENABLE)

Note: This parameter is for advanced users

Harmonic Notch Filter enable

Harmonic Notch Filter base frequency (INS_HNTC2_FREQ)

Note: This parameter is for advanced users

Harmonic Notch Filter base center frequency in Hz. This is the center frequency for static notches, the center frequency for Throttle based notches at the reference thrust value, and the minimum limit of center frequency variation for all other notch types. This should always be set lower than half the backend gyro rate (which is typically 1Khz).

Harmonic Notch Filter bandwidth (INS_HNTC2_BW)

Note: This parameter is for advanced users

Harmonic Notch Filter bandwidth in Hz. This is typically set to half the base frequency. The ratio of base frequency to bandwidth determines the notch quality factor and is fixed across harmonics.

Harmonic Notch Filter attenuation (INS_HNTC2_ATT)

Note: This parameter is for advanced users

Harmonic Notch Filter attenuation in dB. Values greater than 40dB will typically produce a hard notch rather than a modest attenuation of motor noise.

Harmonic Notch Filter harmonics (INS_HNTC2_HMNCS)

Note: This parameter is for advanced users

Bitmask of harmonic frequencies to apply Harmonic Notch Filter to. This option takes effect on the next reboot. A value of 0 disables this filter. The first harmonic refers to the base frequency.

Harmonic Notch Filter reference value (INS_HNTC2_REF)

Note: This parameter is for advanced users

A reference value of zero disables dynamic updates on the Harmonic Notch Filter and a positive value enables dynamic updates on the Harmonic Notch Filter. For throttle-based scaling, this parameter is the reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter. For RPM and ESC telemetry based tracking, this parameter is set to 1 to enable the Harmonic Notch Filter using the RPM sensor or ESC telemetry set to measure rotor speed. The sensor data is converted to Hz automatically for use in the Harmonic Notch Filter. This reference value may also be used to scale the sensor data, if required. For example, rpm sensor data is required to measure heli motor RPM. Therefore the reference value can be used to scale the RPM sensor to the rotor RPM.

Harmonic Notch Filter dynamic frequency tracking mode (INS_HNTC2_MODE)

Note: This parameter is for advanced users

Harmonic Notch Filter dynamic frequency tracking mode. Dynamic updates can be throttle, RPM sensor, ESC telemetry or dynamic FFT based. Throttle-based harmonic notch cannot be used on fixed wing only planes. It can for Copters, QuaadPlane(while in VTOL modes), and Rovers.

Harmonic Notch Filter options (INS_HNTC2_OPTS)

Note: This parameter is for advanced users

Harmonic Notch Filter options. Triple and double-notches can provide deeper attenuation across a wider bandwidth with reduced latency than single notches and are suitable for larger aircraft. Multi-Source attaches a harmonic notch to each detected noise frequency instead of simply being multiples of the base frequency, in the case of FFT it will attach notches to each of three detected noise peaks, in the case of ESC it will attach notches to each of four motor RPM values. Loop rate update changes the notch center frequency at the scheduler loop rate rather than at the default of 200Hz. If both double and triple notches are specified only double notches will take effect.

Throttle notch min frequency ratio (INS_HNTC2_FM_RAT)

Note: This parameter is for advanced users

The minimum ratio below the configured frequency to take throttle based notch filters when flying at a throttle level below the reference throttle. Note that lower frequency notch filters will have more phase lag. If you want throttle based notch filtering to be effective at a throttle up to 30% below the configured notch frequency then set this parameter to 0.7. The default of 1.0 means the notch will not go below the frequency in the FREQ parameter.

Logging File and Block Backend buffer size max (in kibibytes) (LOG_FILE_BUFSIZE)

The File and Block backends use a buffer to store data before writing to the block device. Raising this value may reduce "gaps" in your SD card logging but increases memory usage. This buffer size may be reduced to free up available memory

Enable logging while disarmed (LOG_DISARMED)

If LOG_DISARMED is set to 1 then logging will be enabled at all times including when disarmed. Logging before arming can make for very large logfiles but can help a lot when tracking down startup issues and is necessary if logging of EKF replay data is selected via the LOG_REPLAY parameter. If LOG_DISARMED is set to 2, then logging will be enabled when disarmed, but not if a USB connection is detected. This can be used to prevent unwanted data logs being generated when the vehicle is connected via USB for log downloading or parameter changes. If LOG_DISARMED is set to 3 then logging will happen while disarmed, but if the vehicle never arms then the logs using the filesystem backend will be discarded on the next boot.

Enable logging of information needed for Replay (LOG_REPLAY)

If LOG_REPLAY is set to 1 then the EKF2 and EKF3 state estimators will log detailed information needed for diagnosing problems with the Kalman filter. LOG_DISARMED must be set to 1 or 2 or else the log will not contain the pre-flight data required for replay testing of the EKF's. It is suggested that you also raise LOG_FILE_BUFSIZE to give more buffer space for logging and use a high quality microSD card to ensure no sensor data is lost.

Stop logging to current file on disarm (LOG_FILE_DSRMROT)

When set, the current log file is closed when the vehicle is disarmed. If LOG_DISARMED is set then a fresh log will be opened. Applies to the File and Block logging backends.

Maximum AP_Logger MAVLink Backend buffer size (LOG_MAV_BUFSIZE)

Note: This parameter is for advanced users

Maximum amount of memory to allocate to AP_Logger-over-mavlink

Timeout before giving up on file writes (LOG_FILE_TIMEOUT)

This controls the amount of time before failing writes to a log file cause the file to be closed and logging stopped.

Old logs on the SD card will be deleted to maintain this amount of free space (LOG_FILE_MB_FREE)

Set this such that the free space is larger than your largest typical flight log

Maximum logging rate for file backend (LOG_FILE_RATEMAX)

This sets the maximum rate that streaming log messages will be logged to the file backend. A value of zero means that rate limiting is disabled.

Maximum logging rate for mavlink backend (LOG_MAV_RATEMAX)

This sets the maximum rate that streaming log messages will be logged to the mavlink backend. A value of zero means that rate limiting is disabled.

Maximum logging rate for block backend (LOG_BLK_RATEMAX)

This sets the maximum rate that streaming log messages will be logged to the block backend. A value of zero means that rate limiting is disabled.

Maximum logging rate when disarmed (LOG_DARM_RATEMAX)

This sets the maximum rate that streaming log messages will be logged to any backend when disarmed. A value of zero means that the normal backend rate limit is applied.

Maximum number of log files (LOG_MAX_FILES)

Note: This parameter is for advanced users

This sets the maximum number of log file that will be written on dataflash or sd card before starting to rotate log number. Limit is capped at 500 logs.

Range of travel (SERVO_VOLZ_RANGE)

Range to map between 1000 and 2000 PWM. Default value of 200 gives full +-100 deg range of extended position command. This results in 0.2 deg movement per US change in PWM. If the full range is not needed it can be reduced to increase resolution. 40 deg range gives 0.04 deg movement per US change in PWM, this is higher resolution than possible with the VOLZ protocol so further reduction in range will not improve resolution. Reduced range does allow PWMs outside the 1000 to 2000 range, with 40 deg range 750 PWM results in a angle of -30 deg, 2250 would be +30 deg. This is still limited by the 200 deg maximum range of the actuator.

TERRAIN_ Parameters

Terrain data enable (TERRAIN_ENABLE)

Note: This parameter is for advanced users

enable terrain data. This enables the vehicle storing a database of terrain data on the SD card. The terrain data is requested from the ground station as needed, and stored for later use on the SD card. To be useful the ground station must support TERRAIN_REQUEST messages and have access to a terrain database, such as the SRTM database.

Terrain grid spacing (TERRAIN_SPACING)

Note: This parameter is for advanced users

Distance between terrain grid points in meters. This controls the horizontal resolution of the terrain data that is stored on te SD card and requested from the ground station. If your GCS is using the ArduPilot SRTM database like Mission Planner or MAVProxy, then a resolution of 100 meters is appropriate. Grid spacings lower than 100 meters waste SD card space if the GCS cannot provide that resolution. The grid spacing also controls how much data is kept in memory during flight. A larger grid spacing will allow for a larger amount of data in memory. A grid spacing of 100 meters results in the vehicle keeping 12 grid squares in memory with each grid square having a size of 2.7 kilometers by 3.2 kilometers. Any additional grid squares are stored on the SD once they are fetched from the GCS and will be loaded as needed.

Note: This parameter is for advanced users

The maximum adjustment of terrain altitude based on the assumption that the vehicle is on the ground when it is armed. When the vehicle is armed the location of the vehicle is recorded, and when terrain data is available for that location a height adjustment for terrain data is calculated that aligns the terrain height at that location with the altitude recorded at arming. This height adjustment is applied to all terrain data. This parameter clamps the amount of adjustment. A value of zero disables the use of terrain height adjustment.

Waypoint Acceleration (WPNAV_ACCEL)

Defines the horizontal acceleration in cm/s/s used during missions

Waypoint Vertical Acceleration (WPNAV_ACCEL_Z)

Defines the vertical acceleration in cm/s/s used during missions

Waypoint missions use rangefinder for terrain following (WPNAV_RFND_USE)

Note: This parameter is for advanced users

This controls if waypoint missions use rangefinder for terrain following

Waypoint Jerk (WPNAV_JERK)

Defines the horizontal jerk in m/s/s used during missions

Waypoint Terrain following altitude margin (WPNAV_TER_MARGIN)

Note: This parameter is for advanced users

Waypoint Terrain following altitude margin. Vehicle will stop if distance from target altitude is larger than this margin (in meters)

Waypoint Cornering Acceleration (WPNAV_ACCEL_C)

Defines the maximum cornering acceleration in cm/s/s used during missions. If zero uses 2x accel value.

WVANE_ Parameters

Enable (WVANE_ENABLE)

Enable weather vaning. When active, the aircraft will automatically yaw into wind when in a VTOL position controlled mode. Pilot yaw commands override the weathervaning action.

Weathervaning gain (WVANE_GAIN)

This converts the target roll/pitch angle of the aircraft into the correcting (into wind) yaw rate. e.g. Gain = 2, roll = 30 deg, pitch = 0 deg, yaw rate = 60 deg/s.

Weathervaning min angle (WVANE_ANG_MIN)

The minimum target roll/pitch angle before active weathervaning will start. This provides a dead zone that is particularly useful for poorly trimmed quadplanes.

Weathervaning min height (WVANE_HGT_MIN)

Above this height weathervaning is permitted. If a range finder is fitted or if terrain is enabled, this parameter sets height AGL. Otherwise, this parameter sets height above home. Set zero to ignore minimum height requirement to activate weathervaning.

Weathervaning max ground speed (WVANE_SPD_MAX)

Below this ground speed weathervaning is permitted. Set to 0 to ignore this condition when checking if vehicle should weathervane.

Weathervaning max vertical speed (WVANE_VELZ_MAX)

The maximum climb or descent speed that the vehicle will still attempt to weathervane. Set to 0 to ignore this condition to get the aircraft to weathervane at any climb/descent rate. This is particularly useful for aircraft with low disc loading that struggle with yaw control in decent.

Takeoff override (WVANE_TAKEOFF)

Override the weather vaning behaviour when in takeoffs

Landing override (WVANE_LAND)

Override the weather vaning behaviour when in landing

Weathervaning options (WVANE_OPTIONS)

Options impacting weathervaning behaviour

ZIGZ_ Parameters

ZigZag auto enable/disable (ZIGZ_AUTO_ENABLE)

Note: This parameter is for advanced users

Allows you to enable (1) or disable (0) ZigZag auto feature

Auto sprayer in ZigZag (ZIGZ_SPRAYER)

Note: This parameter is for advanced users

Enable the auto sprayer in ZigZag mode. SPRAY_ENABLE = 1 and SERVOx_FUNCTION = 22(SprayerPump) / 23(SprayerSpinner) also must be set. This makes the sprayer on while moving to destination A or B. The sprayer will stop if the vehicle reaches destination or the flight mode is changed from ZigZag to other.

The delay for zigzag waypoint (ZIGZ_WP_DELAY)

Note: This parameter is for advanced users

Waiting time after reached the destination

Sideways distance in ZigZag auto (ZIGZ_SIDE_DIST)

Note: This parameter is for advanced users

The distance to move sideways in ZigZag mode

Sideways direction in ZigZag auto (ZIGZ_DIRECTION)

Note: This parameter is for advanced users

The direction to move sideways in ZigZag mode

Total number of lines (ZIGZ_LINE_NUM)

Note: This parameter is for advanced users

Total number of lines for ZigZag auto if 1 or more. -1: Infinity, 0: Just moving to sideways
