AIRSPEED INDICATOR

Refer to the Pilot's Operating Handbook (POH) for airspeed criteria and Vspeed values.
NOTE:
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 ), at which point it turns red.

A color-coded (red, white, green, yellow, and red/white 'barber pole") 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 ). A red range is also present for low speed awareness.

The Airspeed Trend Vector is a vertical, magenta line that appears to the right of the color-coded speed
range strip when airspeed is either accelerating or decelerating. One end of the magenta line is anchored to
the tip of the airspeed pointer while the other end moves continuously up or down corresponding to the rate
of acceleration or deceleration. For any constant rate of acceleration or deceleration, the moving end of the
line shows approximately what the indicated airspeed value will be in six seconds. If the trend vector crosses
V , the text of the actual airspeed readout changes to yellow. The trend vector is absent if the speed remains
NE
constant or if any data needed to calculate airspeed is not available due to a system failure.
