AUTOMATIC FLIGHT CONTROL SYSTEM
When airspeed increases (as a result of adding power/thrust) to above the IAS at which stall warning turns
off, plus two knots, the autopilot will cause the aircraft to pitch up until recapturing the vertical reference and
the vertical and lateral flight director modes will change from armed to active.
NON-ALTITUDE CRITICAL MODES (VS, VNAV, IAS,)
If the aircraft decelerates to an IAS below the minimum commandable autopilot airspeed, a red “UNDERSPEED
PROTECT ACTIVE” annunciation (Figure 7-9) will appear to the right of the vertical speed indicator. The
vertical flight director mode will change from active to armed (Figure 7-10), and the autopilot will cause
the aircraft to pitch down until reaching a pitch attitude at which IAS equals the minimum commandable
autopilot airspeed.
