Note 3: The target lock feature tracks a target up to 55° tilt angle. For example, if
a ship moves from position A to position D, the target lock works
between positions A and B. The tilt angle is fixed between positions B
and C is 55°, however calculation continues internally. Target lock is
restarted after position C.
