AIRSPEED INDICATOR
NOTE:
Refer to the Pilot’s Operating Handbook (POH) for speed criteria and Vspeed values.
The Airspeed Indicator displays airspeed on a rolling number gauge using a moving tape. 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, 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 overspeed (V
MO
), at which point
it turns red.

Figure 2-3 Airspeed Indicator
A color-coded (white, green, and red/white “barber pole”) speed range strip is located on the moving tape.
The colors denote flaps operating range, normal operating range, and overspeed (V
MO
). A red range is also
present for low speed awareness.
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
MO
, 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.
