POSITION INVALID
The selected position sensor is sending invalid position data. The position is currently being deter-
mined by dead reckoning; therefore, as the position sensor, EP is now displayed.
After acknowledgement, the system automatically recommends a substitute sensor and displays
its data in the Multidisplay. The sensor which is now selected by the operator continues to be
treated as a substitute sensor, i.e. as soon as the position sensor which led to the POSITION
INVALID alarm is sending valid data again, the POSITION VALID alarm appears.
If the substitute sensor is no longer to be classified as such, that sensor or some other one must
be selected anew. After that, the POSITION VALID alarm no longer appears.
Alternatively, it is possible to switch over to EP = Estimated Position.
POSITION TIMEOUT
Data are no longer being received from the selected position sensor.
The position is currently being determined by dead reckoning; therefore, as the position sensor, EP
is now displayed.
After acknowledgement, the system automatically recommends a substitute sensor and displays
its data in the Multidisplay. The sensor which is now selected by the operator continues to be
treated as a substitute sensor, i.e. as soon as the position sensor which led to the POSITION
TIMEOUT alarm is sending valid data again, the POSITION VALID alarm appears.
If the substitute sensor is no longer to be classified as such, that sensor or some other one must
be selected anew. After that, the POSITION VALID alarm no longer appears.
Alternatively, it is possible to switch over to EP = Estimated Position.
POSITION VALID
The position sensor which had given the POSITION INVALID or POSITION TIMEOUT alarm is
again sending valid data.
After acknowledgement, the system displays the data of the sensor which had given the POSI-
TION INVALID or POSITION TIMEOUT alarm. After checking the new sensor-data, either
confirm this sensor by clicking on the SELECT button or select some other sensor.
SENSOR MASTER CHANGED
This radar system has taken over the task of managing the navigation data because the item of
equipment which had previously been performing that task has failed. It must be assumed that
sensor data which the failed item of equipment had previously been passing on to the system are
now missing.
SENSOR MASTER FAILS
The radar system which manages the navigation data has failed. The management task has been
taken over by a different radar system. It must be assumed that sensor data which the failed radar
system had previously been passing on to the system are now missing.
