2.1.1 AIRSPEED INDICATOR

NOTE: The G5 Vspeed Reference values depend upon the aircraft's specific
system configuration and may vary from the examples discussed in this sec-
tion.
The Airspeed Indicator displays airspeed on a rolling number gauge using a moving
tape. 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
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
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
airspeed display 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.
