// @Description: When enabled, this adds user stick input to the control surfaces in auto modes, allowing the user to have some degree of flight control without changing modes. There are two types of stick mixing available. If you set STICK_MIXING to 1 then it will use "fly by wire" mixing, which controls the roll and pitch in the same way that the FBWA mode does. This is the safest option if you usually fly ArduPlane in FBWA or FBWB mode. If you set STICK_MIXING to 2 then it will enable direct mixing mode, which is what the STABILIZE mode uses. That will allow for much more extreme maneuvers while in AUTO mode.
// @Description: Minimum GPS ground speed in m/s before un-suppressing throttle in auto-takeoff. This is meant to be used for catapult launches where you want the motor to engage only after the plane leaves the catapult. Note that the GPS velocity will lag the real velocity by about 0.5seconds.
// @DisplayName: Takeoff throttle min acceleration
// @Description: Minimum forward acceleration in m/s/s before un-suppressing throttle in auto-takeoff. This is meant to be used for hand launches with a tractor style (front engine) plane. If this is set then the auto takeoff will only trigger if the pitch of the plane is between -30 and +45 degrees, and the roll is less than 30 degrees. This makes it less likely it will trigger due to carrying the plane with the nose down.
// @Description: This controls the maximum bank angle in degrees during flight modes where level flight is desired, such as in the final stages of landing, and during auto takeoff. This should be a small angle (such as 5 degrees) to prevent a wing hitting the runway during takeoff or landing. Setting this to zero will completely disable heading hold on auto takeoff and final landing approach.
// @Description: The percent of mixing between GPS altitude and baro altitude. 0 = 100% gps, 1 = 100% baro. It is highly recommend that you not change this from the default of 1, as GPS altitude is notoriously unreliable. The only time I would recommend changing this is if you have a high altitude enabled GPS, and you are dropping a plane from a high altitude baloon many kilometers off the ground.
// @Description: This sets what algorithm will be used for altitude control. The default is to select the algorithm based on whether airspeed is enabled. If you set it to 1, then the airspeed based algorithm won't be used for altitude control, but airspeed can be used for other flight control functions
// @Description: This is added to the target altitude in automatic flight. It can be used to add a global altitude offset to a mission, or to adjust for barometric pressure changes
// @Description: Defines the distance from the waypoint center, the plane will maintain during a loiter. If you set this value to a negative number then the default loiter direction will be counter-clockwise instead of clockwise.
// @Description: Reverse sense of elevator in FBWB. When set to 0 up elevator (pulling back on the stick) means to lower altitude. When set to 1, up elevator means to raise altitude.
// @Description: This sets the rate in m/s at which FBWB will change its target altitude for full elevator deflection. Note that the actual climb rate of the aircraft can be lower than this, depending on your airspeed and throttle control settings. If you have this parameter set to the default value of 2.0, then holding the elevator at maximum deflection for 10 seconds would change the target altitude by 20 meters.
// @Description: maximum percentage change in throttle per second. A setting of 10 means to not change the throttle by more than 10% of the full throttle range in one second
// @Description: When throttle is supressed in auto mode it is normally forced to zero. If you enable this option, then while suppressed it will be manual throttle. This is useful on petrol engines to hold the idle throttle manually while waiting for takeoff
// @Description: If this is set then when in STABILIZE or FBWA mode the throttle is a direct passthru from the transmitter. This means the THR_MIN and THR_MAX settings are not used in these modes. This is useful for petrol engines where you setup a throttle cut switch that suppresses the throttle below the normal minimum.
// @Description: Battery voltage to trigger failsafe. Set to 0 to disable battery voltage failsafe. If the battery voltage drops below this voltage then the plane will RTL
// @Units: Volts
// @User: Standard
GSCALAR(fs_batt_voltage, "FS_BATT_VOLTAGE", 0),
// @Param: FS_BATT_MAH
// @DisplayName: Failsafe battery milliAmpHours
// @Description: Battery capacity remaining to trigger failsafe. Set to 0 to disable battery remaining failsafe. If the battery remaining drops below this level then the plane will RTL
// @Description: Enable ground control station telemetry failsafe. Failsafe will trigger after 20 seconds of no MAVLink heartbeat messages. WARNING: Enabling this option opens up the possibility of your plane going into failsafe mode and running the motor on the ground it it loses contact with your ground station. If this option is enabled on an electric plane then either use a separate motor arming switch or remove the propeller in any ground testing.
// @Description: Enable VTail output in software. If enabled then the APM will provide software VTail mixing on the elevator and rudder channels. There are 4 different mixing modes available, which refer to the 4 ways the elevator can be mapped to the two VTail servos. Note that you must not use VTail output mixing with hardware pass-through of RC values, such as with channel 8 manual control on an APM1. So if you use an APM1 then set FLTMODE_CH to something other than 8 before you enable VTAIL_OUTPUT. Please also see the MIXING_GAIN parameter for the output gain of the mixer.
// @Description: Enable software elevon output mixer. If enabled then the APM will provide software elevon mixing on the aileron and elevator channels. There are 4 different mixing modes available, which refer to the 4 ways the elevator can be mapped to the two elevon servos. Note that you must not use elevon output mixing with hardware pass-through of RC values, such as with channel 8 manual control on an APM1. So if you use an APM1 then set FLTMODE_CH to something other than 8 before you enable ELEVON_OUTPUT. Please also see the MIXING_GAIN parameter for the output gain of the mixer.
// @Description: The gain for the Vtail and elevon output mixers. The default is 0.5, which ensures that the mixer doesn't saturate, allowing both input channels to go to extremes while retaining control over the output. Hardware mixers often have a 1.0 gain, which gives more servo throw, but can saturate. If you don't have enough throw on your servos with VTAIL_OUTPUT or ELEVON_OUTPUT enabled then you can raise the gain using MIXING_GAIN. The mixer allows outputs in the range 900 to 2100 microseconds.
// @Description: RC channel to use to reset the mission to the first waypoint. When this channel goes above 1750 the mission is reset. Set RST_MISSION_CH to 0 to disable.
// @Description: offset to add to pitch - used for in-flight pitch trimming. It is recommended that instead of using this parameter you level your plane correctly on the ground for good flight attitude.
// @Description: Return to launch target altitude. This is the altitude the plane will aim for and loiter at when returning home. If this is negative (usually -1) then the plane will use the current altitude at the time of entering RTL.
// @Description: This is the minimum altitude in centimeters that FBWB will allow. If you attempt to descend below this altitude then the plane will level off. A value of zero means no limit.
// @Description: Setting this to Enabled(1) will enable the compass. Setting this to Disabled(0) will disable the compass. Note that this is separate from COMPASS_USE. This will enable the low level senor, and will enable logging of magnetometer data. To use the compass for navigation you must also set COMPASS_USE to 1.
// @Description: The speed in meters per second at which to engage FLAP_1_PERCENT of flaps. Note that FLAP_1_SPEED should be greater than or equal to FLAP_2_SPEED
// @Description: The speed in meters per second at which to engage FLAP_2_PERCENT of flaps. Note that FLAP_1_SPEED should be greater than or equal to FLAP_2_SPEED
// @Description: Used to convert the voltage of the voltage sensing pin (BATT_VOLT_PIN) to the actual battery's voltage (pin voltage * INPUT_VOLTS/1024 * VOLT_DIVIDER)
// @Description: Setting this to 0 ~ 13 will enable battery current sensing on pins A0 ~ A13. For the 3DR power brick on APM2.5 it should be set to 13. On the PX4 it should be set to 100.
// @Description: Setting this to 0 ~ 13 will enable battery current sensing on pins A0 ~ A13. For the 3DR power brick on APM2.5 it should be set to 12. On the PX4 it should be set to 101.
// @Description: A RC input channel number to enable inverted flight. If this is non-zero then the APM will monitor the correcponding RC input channel and will enable inverted flight when the channel goes above 1750.
// @Description: This controls whether real servo controls are used in HIL mode. If you enable this then the APM will control the real servos in HIL mode. If disabled it will report servo values, but will not output to the real servos. Be careful that your motor and propeller are not connected if you enable this option.
