2.1 FLIGHT INSTRUMENTS
AIRSPEED INDICATOR
Refer to the Aircraft Flight Manual Supplement (AFMS) for airspeed criteria and Vspeed values.
NOTE:
The Airspeed Indicator displays airspeed on a moving tape rolling number gauge. The true airspeed is
displayed in knots below the Airspeed Indicator. The numeric labels and major tick marks on the moving
tape are marked at intervals of 10 knots. The minor tick marks on the moving tape are marked at intervals of
five knots. Speed indication starts at 20 knots, with 60 knots of airspeed viewable at any time. The indicated
airspeed is displayed inside the black pointer. The pointer remains black until reaching never-exceed speed
(V
), at which point it turns red.

A color-coded (white, green, yellow, and red) speed range strip is located on the moving tape. The colors
denote flaps operating range, normal operating range, caution range, and never-exceed speed (V
yellow ranges are also present for low speed awareness. For EASA-certified aircraft, the yellow low airspeed
awareness band is not shown and the limits on the other lower speed ranges differ (refer to the AFMS for speed
criteria).
The Airspeed Trend Vector is a vertical, magenta line, extending up or down on the airspeed scale, shown
to the right of the color-coded speed range strip. The end of the trend vector corresponds to the predicted
airspeed in 6 seconds if the current rate of acceleration is maintained. If the trend vector crosses V
of the actual airspeed readout changes to yellow. The trend vector is absent if the speed remains constant or if
any data needed to calculate airspeed is not available due to a system failure.
