If the planned change of the course is not to be executed: Switch over to Course or Heading
mode and steer with the joystick or appologize a manual steering mode.
If the preceding TP Waypoint Approaching warning has been acknowledged, the TP WOP
Execution alarm appears initially as a warning, with a low intensity acoustic signal. If the TP
Waypoint Approaching warning was not acknowledged, the TP WOP Execution alarm appears
together with an intensive acoustic signal.
If the warning TP WOP Execution is not acknowledged within 30 seconds, an intensive acoustic
signal is generated even if the TP WPT Waypoint Approaching alarm was acknowledged before-
hand. If not acknowleged 30 seconds after appearance of the WOP alarm, the TRACKPILOT Alarm
signal is generated for the purpose of triggering an external back up navigator alarm. See 2.2.6 on
page V-32.
If the manoeuvre period from one wheel-over point to the following one is less than 30 seconds,
the TP WOP Execution alarm of the second wheel-over point does not appear until after the first
wheel-over point has been passed but already during execution of the first manoeuvre.
TP Trackpilot Failure
The TRACKPILOT reports an internal fault, and is no longer controlling the rudder.
Until the cause of the alarm has been eliminated, the status FAILURE is shown in the operational
mode field of the TRACKPILOT data display as well as on the Conning display.
Remedy (after the switch-over to manual steering has taken place):
- Attempt to reconnect the Trackpilot to the steering gear.
- Restart the TRACKPILOT (See 2.8 on page G-49 for details).
- Check the TRACKPILOT electronics unit, the TRACKPILOT Interface and their power supply.
If installed, switch over to the second TRACKPILOT.
Regardless of whether this alarm is acknowledged or not, the planned change of
the course takes place at the WOP.
When this alarm appears, a switch-over to manual steering must be performed
immediately.
