Powerplant Flashcards
What occurs if EGT exceeds the red line limit?
Maximum exceedance value attained will be displayed
What value is represented by the command sector on the N1 (B767) indicator?
The momentary difference between the command
thrust level and actual N1
What system is controlled by the thrust management computer?
Autothrottles
What is calculated by the thrust management computer?
Maximum EPR (757) or N1 (767) reference
What occurs if one EICAS CRT fails?
Engine parameters are displayed in Compacted Mode
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 does the L or R ENG STARTER EICAS message indicate?
Engine starter valve is not in the commanded position
What does the L or R STARTER CUTOUT EICAS message indicate?
Engine start valve is open above engine RPM at which
cutout should occur
When does the red Maximum Start EGT limit radial remain in view during engine
start?
Until the engine start is completed
Where can the assumed temperature be entered manually?
TAKEOFF REF page on the FMC or selected with the
Assumed Temperature selector on the TMSP
What color is the REV annunciation on EICAS when the thrust reverser is unlocked
and in transit?
Amber
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 commanded position
(PW) Max motoring speed occurs when _______?
N2 acceleration is less than 1% in 5 seconds.
(PW) What does the green TAI bug on the N1 parameter 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 EICAS message indicate?
EEC using N2 as control parameter
(RR) What does the Fuel Control switch RICH position accomplish?
Initially schedules additional fuel for start
(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
