AIRSPEED INDICATOR
NOTE: The G3X Vspeed Reference values and Flaps Tick Mark values depend
upon the aircraft’s specific system configuration and may vary from the
examples discussed in this section.
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. Speed indication starts at 30 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.
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
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.
