14. The system failures are detected by
A watchdog signal
Central Maintenance Computer
15. It increases the confidence of system
serviceability
Simple bite
Built In Test (BIT) feature
16. The result of simple bite test (self test)
is indicated by a Green / Red LED (as GO/NO GO)
is visible only when the aircraft is in air
17. Classification of failures as Warning, Caution or
Advisories, is determined by
Engine Indicating & Crew Alerting System (EICAS)
Fault Warning Computer (FWC)
18. It generates warning, caution & advisories
EICAS
Fault Warning Computer (FWC)
19. Engine primary information is displayed on
Upper EICAS
Lower EICAS
20. The system faults are recorded in
Fault Warning Computer (FWC)
Central Maintenance Computer (CMC)
21. Engine secondary information is displayed on
Upper EICAS
Lower EICAS
