Trial maneuver takes place in three minutes with the letter “T” displayed at the bottom of
the screen. If any tracked target is predicted to be on a collision course with own ship (that
is, the target ship comes within preset CPA/TCPA limits), the target plot symbol changes
to a triangle and flashes. If this happens, change own ship’s trial speed, course or delay
time to obtain a safe maneuver. The trial maneuver is automatically terminated and the
normal radar picture is restored three minutes later.
