The airspeed hold mode is engaged by pressing the A/S button on the mode controller. All other
FDC pitch axis modes previously selected (ALT, G/S, V/S or GA) are over ridden.
The airspeed observed at mode engagement will be maintained automatically. The FDC computer
uses airspeed error to generate pitch inputs to the autopilot computer. Those piloting inputs are
also displayed by the pitch command bar on the ADI after summation with the pitch attitude provid-
ed by the gyro-horizon. Should G.H. pitch data disappear, the horizontal (pitch) command bar will
bias out of view.
To change the airspeed reference datum, the mode is to be disengaged on the mode controller or
by means of teh DCPL push button on the cyclic stick hand grip. The mode is reengaged when the
desire airspeed reference datum is attained.
Any airspeed deviation of more than +/- 16 kts from the reference airspeed datus shall cause the
AS excessive deviation annunciator to fl ash.
NOTE:
1) Beep-trim and stick release are disabled as soon as A/S mode is effective.
2) The pilot is not supposed to operate these commands unless safety demands.
