Cirrus SR2x

AUTOMATIC FLIGHT CONTROL SYSTEM
NON-ALTITUDE CRITICAL MODES (VS, VNAV, LVL, PIT, IAS)
If the aircraft decelerates to an IAS below the minimum commandable autopilot airspeed, a red “UNDERSPEED
PROTECT ACTIVE” annunciation (Figure 7-45) will appear in the CAS window. The vertical flight director
mode will change from active to armed (Figure 7-46), and the autopilot will cause the aircraft to pitch down
until reaching a pitch attitude at which IAS equals the minimum commandable autopilot airspeed.
