NAV
Description
The navigation page displays information related to the INS and the aircraft's calculated position.
This page can be opened from PDS1.
The upper section displays the current reference date and time.
The safety height can be adjusted at the bottom of the page.
INS alignment
Before alignment begins, the page displays the coordinates of the primary goal used as the alignment reference. Select ALN to start the alignment sequence.
During alignment, the remaining alignment time is displayed below each corresponding INU.
Once alignment is complete, the page displays the aircraft's current coordinates and altitude as calculated by the inertial navigation system, together with the current positional deviation between the two INUs.
