As described in the following table, when the aircraft reaches
predetermined airspeeds a yellow MINSPD annunciation will appear
above the airspeed indicator and a single aural "AIRSPEED" will
sound to alert the pilot to an impending underspeed condition.

The system differentiates two types of vertical modes based on which
vertical Flight Director mode is selected; Altitude-Critical - where
terrain hazards are more probable and minimized altitude loss is
critical and Non-Altitude Critical - which generally correspond with
activities that can afford exchange of altitude for airspeed without
introducing terrain hazards.
Altitude-Critical Mode (ALT, GS, GP, GA, TO)
Upon stall warning system activation, the AFCS will abandon its Flight
Director and Autopilot reference modes and sacrifice altitude for
airspeed. The system will hold wings level and airspeed will
progressively increase by 1 knot per second until stall warning
becomes inactive. The system will then increase airspeed an
additional 2 knots above the speed at which the stall warning
discontinued. Recovery may be initiated in one of three ways:
1. Add sufficient power to recover to a safe flight condition.
If a small power addition is made, the AFCS will pitch the aircraft
to maintain speed reference. If a large power addition is made the
AFCS recognizes it via acceleration and the AP/FD will transition
to a nose-up pitch to aggressively return to original altitude or
glidepath/slope.
2. Disengage Autopilot via AP DISC and manually fly.
3. Change Autopilot modes to one in which the AFCS can maintain
(such as VS with a negative rate).
