b) Rate of Turn.
c) Off Heading Limit.
d) Heading Source in use.
NB. Safeguards are an inherent feature of the Autopilot software to ensure safe track
steering operation.
e) The Autopilot will prevent the Track Control System from carrying out a
Rate of Turn which exceeds the Autopilots internal maximum set limit.
