Navigation Flashcards
What information may be available if the IR Rotary Selectors are set to ATT?
- IR mode supplying only attitude and heading information, if the system loses its ability to navigate.
- The heading must be entered through the CDU keyboard and has to be reset frequently (10min).
What are the 3 occasions when the ALIGN light will flash?
- ALIGN fault
- No present position entry after 10min
- Different between position at shutdown and entered position exceeds 1 degree of latitude or longitude
- If the aircraft moves during alignment (windy day).
When does the ON BAT light illuminate?
Comes on amber when one or more IRs is supplied only by the A/C battery. It also comes on for a few seconds at the beginning of the alignment, but not for a fast realignment.
What should NOT be tested during APU start?
Compass, because of the location of the APU power on contractor in the cockpit the PAU start sequence may disturb the compass reading.
