Low Speed Awareness Bar – A low speed awareness bar
indicates the aircraft condition relative to a stall. The bar starts from
the bottom right side of the airspeed tape. When the
reaches the airspeed reference line, the aircraft is at about 0.7_
normalized angle–of–attack (AOA). When the
reaches the airspeed reference line (as calculated by an AOA input),
the stickshaker activates. Color bands represent V
described in Table 3–23.

Angle–of–Attack (AOA) Failure Annunciator – If angle–of–attack
becomes invalid,
of the airspeed tape.

Mach Display – The digital Mach display is the present Mach
number. It is located below the airspeed tape. The color of the digits
is always the same as the digital airspeed display. The minimum
Mach that can be displayed is 0.001.
D
Airspeed Digital Display – IAS is displayed as
inside the display window. Current IAS is magnified in the window
and is readable to a 1 knot resolution. When the current airspeed is
equal to or greater than the maximum allowable airspeed (V
digits turn red. When the airspeed trend vector exceeds V
knot, the rolling digits turn
airspeeds below 40 knots, the digits are removed. For airspeeds
greater than 450 knots, the displayed value remains at 450.
D
Airspeed Scale – The airspeed scale is a moving tape display with
fixed pointer and calibrated airspeed marks. The white scale
markings on the tape are in 10–knot increments. The scale digits
move such that larger numbers come from the top of the display. If
V /M is exceeded, the numbers turn red.
