CDS BITE PAGES - INFLIGHT FAULTS
General
To do a check of the inflight faults, select INFLIGHT FAULTS on line select key (LSK) 2L from the CDS MAIN MENU. This shows the INFLIGHT FAULTS Leg Menu page.
The DEU stores faults for 64 flight legs. The DEU can store up to 32 faults for each flight leg.
A new flight leg starts when the airplane has an airspeed of more than 80 knots. The flight leg ends when the airspeed is less than 75 knots. If a fault occurs on the ground with engines off, the DEU shows the fault as a current fault in CURRENT STATUS. If the fault exists when a new flight leg starts, the DEU stores the fault in the new flight leg.
INFLIGHT FAULTS Leg Menu Page
The INFLIGHT FAULTS leg menu page shows a list of the flight legs that have faults in the DEU memory. The number of inflight faults for the flight leg shows next to the flight leg number. The time the flight leg started shows under the flight leg.
To show the faults for a flight leg, select the LSK next to the flight leg. This shows the first fault in that flight leg. Leg 01 is the most current flight leg.
INFLIGHT FAULTS Fault Page
A single fault shows on a page. The number of inflight faults for this flight leg shows on the top of the page. The number of pages is the number of inflight faults for this flight leg.
