(It is assumed that valid track data is available to the Autopilot system).
(i) With the Autopilot engaged (ON)
use the “TRACK” key to accept
data.
NB. In the event that no data is
available, the “NO HTS DATA”
alarm will be generated (visual
and audible).
(ii)
Valid Track data acceptance will
be confirmed below the Track
graphic as “HTC DATA”,
“HSC DATA” or “APB DATA” as appropriate and the New Heading to

If the Track Mode Heading to Waypoint is to be rejected – use the “CANCEL”
key.
(If the “Cancel” key is used, a silent period will follow beyond which the
Cancel/Confirm request will be repeated and this sequence will continue until
the Track Heading is accepted or Track Mode is set to “OFF”).

To disengage the Track Mode at any time, use the “TRACK” key when it will
be noted that the Track graphic will automatically be removed from the
Control Unit display and the red corner LED in the “TRACK” key will turn off.
