AUTOPILOT ENGAGEMENT
Autopilot is engaged via the AP button on the guidance panel. When there are no
vertical or lateral mode active, the autopilot will engage in (PIT) and (ROL) FD
modes.
Autopilot control authority:
•
Roll rate is limited to ± 7.5°/sec.
•
Pitch rate
•
± 0.3 g’s in straight and level flight
•
maximum 0.7 g’s pitch up in a turn
The autopilot can engage throughout the range:
•
Pitch = ± 50°
•
Roll = ± 75°
•
Once engaged, the autopilot will reduce the pitch and roll angles below control
limits
Autopilot control limits:
•
Roll = ± 35° except in Approach (APP) mode. When in APP mode, the roll limits
are reduced linearly from ± 25°, above 200 feet radio altitude, to ± 5° at zero feet
radio altitude
•
Pitch = ± 20°. In APP mode, the nose-down pitch limit is reduced below 300 feet,
programmed by vertical rate and radio altitude
