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.
