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.
The vertical and lateral flight director modes will change from armed to active. The pitch attitude may be very
high as the aircraft climbs back to the desired altitude. This high pitch angle and rate of climb is intended to
minimize time spent below the desired altitude.

When the airspeed trend vector reaches a predetermined airspeed, a single aural “AIRSPEED” will sound,
alerting the pilot to the impending underspeed condition. If the aircraft decelerates to an IAS below the
minimum commandable autopilot airspeed, a red “UNDERSPEED PROTECT ACTIVE” annunciation will
appear to the right of the vertical speed indicator. The vertical flight director mode will change from active
to armed, and the autopilot will cause the aircraft to pitch down until reaching a pitch attitude at which IAS
equals the minimum commandable autopilot airspeed.
When airspeed increases (as a result of adding power/thrust) to an IAS above the minimum commandable
autopilot airspeed, the autopilot will cause the aircraft to pitch up until recapturing the vertical reference. The
vertical flight director mode will change from armed to active.
