ALPHASEAPILOT MFC
1.12 Using the Track Function (
Section 2.9 & 2.38
)
The Autopilot is equipped with a comprehensive Track Steering facility which is activated by
operation of the “TRACK” key provided the Autopilot System is engaged (ON) and suitable
Track data is available from a proprietary approved GPS/Track Control system/ECDIS etc.
Track Operation is confirmed by red
corner LED illumination of the Track
key and additional display information
for AUTO TRACK STEERING Mode.
Three Track sentence types are
accepted ($XXHTC, $XXHSC, $XXAPB)
all three of which provide the “Heading
to Steer” data required for single or
multi waypoint route steering by the
Autopilot system.
When operating in conjunction with an approved Track Control system sending the
comprehensive “HTC” sentence, complex manoeuvres based on externally ordered ROT &
Radius controlled turns to new headings can be acknowledged and executed by the Autopilot.
