NOTE:
speed criteria and Vspeed values.
The Airspeed Indicator displays airspeed on a rolling number gauge using a moving tape. The true airspeed
(TAS) 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, while minor
tick marks on the moving tape are indicated at intervals of 5 knots. Speed indication starts at 20 knots, with 60
knots of airspeed viewable at any time. The actual airspeed is displayed inside the black pointer. The pointer
remains black until reaching never-exceed speed (V

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
above the never-exceed speed (V
by red/white "barber pole" coloration.
A red low speed awareness range extends up to the low speed awareness velocity, V
is generated as the aircraft approaches a stall condition.
The Airspeed Trend Vector is a vertical, magenta line, extending up or down on the airspeed scale, located
to the right of the color-coded speed range strip. The end of the trend vector displays approximately what
airspeed will be reached in 6 seconds if the current acceleration is maintained. If the trend vector crosses V
the text of the actual airspeed readout changes to yellow while the pointer remains black. 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.
