Parachute Tutorial

To configure the parachute release, first connect to the autopilot using Mission Planner, then open the CONFIG -> Full Parameter List tab, and then set the following parameters.
Set CHUTE_ENABLED = “1”. Then refresh the parameters or restart to view the Chute parameters.
CHUTE_CRT_SINK should be set to the sink rate in m/s, which will trigger the chute release.
CHUTE_ALT_MIN determines the minimum altitude above HOME at which the parachute release is permitted.

 

Set CHUTE_TYPE = “10” for servo release.
CHUTE_SERVO_ON should be set to the servo position required to release the parachute.
CHUTE_SERVO_OFF should be the "resting" servo position, that is, the position where the servo is before the parachute is released.
Set SERVO9_FUNCTION = “27”.

 

*On autopilots with IOMCU (the outputs are marked as MAIN and AUX), it refers to AUX OUT 1 of the Pixhawk. To switch to AUX OUT2, set SERVO10_FUNCTION to 27, and so on.
