AIRSPEED INDICATOR
NOTE: Refer to the Aircraft Flight Manual (AFM) for airspeed criteria and Vspeed values.
The Airspeed Indicator displays airspeed on a moving tape rolling number gauge. The true airspeed is

stripwhenairspeed is either accelerating or decelerating. Oneendofthe magenta line is anchoredtothe
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. 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.
