Lost Position Value In "Course Control" Mode; Track Control - Raytheon NautoPilot NP 5100 Operator's Manual

4.4.6

Lost position value in "Course Control" mode

The Course Control mode is executed for at least 2 minutes and the top bar (yellowish
orange) displays "Dead Reckoning no Position" during this time.
If no valid position is available after 2 minutes, the "Course Control" mode is stopped
and a switchover to "Heading Control" mode is performed (an appropriate message will
be displayed at the top bar).
If a valid position is available, but a position jump is detected, a switchover to "Heading
Control" mode is performed to prevent an unwanted rudder movement.
If a valid position is available without a position jump, the "Course Control" mode
continues, however, all messages (warnings) must be acknowledged.
