AEROPLANES
Section 1 – General-
AUTOPILOT FUNCTIONS
13.2.1 ALTITUDE CRITICAL MODES (ALT, GS, GP, TO, GA, FLC)
When the airspeed trend vector (dedicated algorithm) reaches 65 +/- 2 KIAS a single aural
―AIRSPEED‖ will sound, alerting the pilot to the impending underspeed condition, which
requires pilot action.
If the aircraft decelerates to stall warning and a speed of 65 KIAS is reached, the lateral and
vertical flight director modes will change from active to armed and the autopilot will provide
input causing the aircraft to pitch down and the wings to level.
The aural ―AIRSPEED‖ alert will sound every five seconds.
If aircraft is unintentionally decelerated to 65 KIAS, a MINSPD annunciation posts above
the airspeed tape on PFD in alternating amber and black text. A red ―UNDERSPEED PRO-
TECT ACTIVE‖ annunciation will appear to the right of the vertical speed indicator. USP
will drive the pitch down until the indicated airspeed increases above 70 KIAS or stall warning
turns off, plus two knots (whichever comes first).
When USP disengages, autopilot will cause the aircraft to pitch up until recapturing the vertical
reference (vertical and lateral flight director modes will change from white armed to green ac-
tive).
