LOW AIRSPEED AWARENESS
A red, amber, and white thermometer type display located on the inside of the airspeed scale gives
indication of low airspeed. The white extends from 1.3 V
S1
to 1.2 V

, the amber band extends from 1.2

to 1.1 V

(approximately stick shaker speed), and the red extends from stick shaker speed to the
smaller airspeeds on the tape.
ALTITUDE INDICATION
The altitude display is located to the right of the attitude display on the primary flight display. The
altitude is indicated by means of a vertical tape display which has a “rolling digit” window in the center of an
altitude vertical tape. The resolution of the digits is 20 feet. The hundreds, thousands, and ten thousands
digits are larger digit numerals than the others. The vertical tape moves behind the window and displays a
tape 550 feet both above and below the present indicated altitude, with the larger numbers at the top of the
scale. The range of the altitude window is from -1,000 to 60,000 feet with tick marks located at 500 foot
increments. The scale is labeled in 500 foot intervals and single line chevrons are located at each 500 foot
increment. Double line chevrons are located at each 1000 foot increment. The chevrons extend back to
the approximate midpoint of the altitude tape and are connected with each other by a vertical line. The left
side of the “rolling digit” window has the same angle as the chevrons.
The barometric pressure setting is controlled by a BARO knob at the bottom right of the primary flight
display. A STD button, located next to the BARO knob, allows a change to a baro setting of 29.92 in. Hg.
(or 1013 millibars) by simply pressing it. The baro correction setting display is located just below the
altitude dial. When set to in. Hg. the BARO knob will change the altitude correction by 0.01 in. Hg. per
click.
