AIRSPEED INDICATOR
NOTE:
Refer to the Rotorcraft Flight Manual (RFM) for speed criteria.
The Airspeed Indicator displays airspeed on a moving tape rolling number gauge. The groundspeed 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 indicated 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
NE
), at which point it turns red.

A color-coded (yellow, green, and red) speed range strip is located on the moving tape. The colors denote,
normal operating range, caution range, and never-exceed speed (V
NE
).
A black and white checkered shutter covers the airspeed indication at or below 15 knots, and remains
displayed until reaching 20 knots.
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
NE
, the text 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.
