Glider Pullup from Dive to Normal Flight

Intended to control and automate the pullup of a glider from a free fall dive to normal flight in hihg altitude balloon drops, this feature is not normally included in the firmware (except SITL sims) and a version built using the Custom Firmware Build Server.

The feature is enabled with the PUP_ENABLE parameter. When enabled it adds a new stage to the NAV_ALTITUDE_WAIT mission item, controlled by the PUP_* parameters. This stage controls the pullup maneuver where we do a g-force limited pullup out of a dive, bring the aircraft to a normal flight regime where normal mission commands can take over.

The following parameters apply to this feature:

• PUP_ENABLE

• PUP_ELEV_OFS

• PUP_NG_LIM

• PUP_NG_JERK_LIM

• PUP_PITCH

• PUP_ARSPD_START

• PUP_PITCH_START
