Power Plant Flashcards
What color is the REV annunciation on EICAS when the thrust reverser is unlocked and in transit?
Amber
What does D-TO indicate on EICAS?
Assumed temperature derated takeoff thrust
What is the maximum assumed thrust reduction to takeoff thrust allowed by the thrust management computer?
25% reduction from maximum takeoff thrust or selected climb thrust, whichever is the greater thrust value
What does TO 1 indicate on EICAS?
Takeoff thrust one, climb one preselected
What does TO 2 indicate on EICAS?
Takeoff thrust two, climb two preselected
What does D-TO 2 indicate on EICAS?
Assumed temperature derated takeoff thrust two, climb two preselected
What occurs if one EICAS CRT fails?
Engine parameters are displayed in compacted mode
Prior to engine start, the SPAR VALVE light for the left engine is illuminated. What is the system condition?
Fuel spar valve is not in the commanded position
(PW) Max motoring speed occurs when ____?
N2 acceleration is less than 1% in 5 seconds
Where can the assumed temperature be entered manually?
Take off REF page on the FMC or selected with the assumed temperature selector on the TMSP
When does the red maximum start EGT limit radial remain in view during engine start?
Until the engines start is completed
What does the L or R ENG STARTER EICAS message light indicate?
Engine starter valve is not in the commanded position
What is calculated by the thrust management computer?
Maximum EPR (757) or N1 (767) reference
What does the L or R STARTER CUTOUT EICAS message indicate?
Engine start valve is open above engine RPM at which cutout should occur
(PW) What does the green TAI bug on the N1 perameter indicate?
Engine anti-ice is on and only one engine bleed source is available
(PW) With only one engine bleed source available, what does the amber TAI above the N1 parameter indicate?
N1 is below the reference level
(PW) What does the ENG LIMIT PROT light and the EICAS message indicate?
EEC using N2 as control parameter
(RR) What does the fuel control switch in RICH position accomplish?
Initially schedules additional fuel for start
(767) When derate Climb power (CLB1 or CLB 2) is used, when does it return to maximum climb power (CLB)?
Gradually, starting at 10,000 ft and returns to maximum climb power at 12,000 ft.
(767) What does the ENGINE CONTROLS EICAS message indicate?
Faults are detected in the engine control system
(767) When does the auto relight ignition feature operate?
When N2 drops below idle speed
(767) What is the normal starter duty cycle?
Up to 5 minutes on, followed by 1/2 minute off per minute on
What occurs if EGT exceeds the redline limit?
Maximum exceedance value attained will be displayed
What system is controlled by the thrust management computer?
Autothrottles
