AIRSPEED INDICATOR
NOTE:
G900X Airspeed Indicator markings correspond to Vspeed values provided by the kitplane
manufacturer.
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
NE
), at which point it turns red.

Speed Ranges
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
NE
). 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
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.
