starter shaft failure
Following a dual engine failure/stall procedure, airspeed should be above ____ knots to ensure best windmill start capability. (777-200ER) (Answer requires reference to the QRH.)
250
On a 777-200ER, the minimum oil quantity prior to engine start is ____ quarts.
16
A 300ER Engine Autostart will attempt to start the engines a total of ___ times on the ground?
Three
On a 777-300ER, if an engine is shutdown after selecting APU to Pack operation, the engine cannot be started until?
APU to Pack takeoff mode has been deleted.
The -300ER GE engines use which thrust values in the EEC Normal / Alternate Modes?
Uses N1 for both EEC modes
On the -300ER, single engine taxi is not recommended.
True
Following a dual engine failure/stall procedure, airspeed should be above ____ knots to ensure best windmill start capability (777-300ER).
270
In the Normal mode, the EEC:
Maximum rated thrust is available in any phase of flight by moving the thrust levers to the full forward position.
All of the above.
Maximum EPR (RR) or N1 (GE) represents the maximum rated thrust available from the engine.
Sets thrust by controlling EPR (RR) or N1 (GE) based on thrust lever position.
What indications are NOT monitored by the Auto-Start system during engine start?
Oil pressure and oil temperature
In the alternate mode, EPR (RR) and N1 (GE) are used as the controlling parameter.
False
What condition(s) will NOT cause the EEC to automatically select Approach Idle in-flight?
Equipment Cooling is in the OVERRIDE mode
If the required signals are not available to operate in the normal mode, the EEC automatically uses the alternate mode. In the alternate mode, the EEC schedules N1 as function of thrust lever position.
True
What are the functions of the FUEL CONTROL Switch when selected to the RUN position during an Auto-Start?
Opens the spar fuel valve, arms the engine fuel valve and arms the selected ignitor.
Using info presented on this synoptic, how can the APU be started?
Start the APU normally, as it will automatically use its own battery for an electric start.
The air synoptic indicates the Aft and Bulk Cargo temperature controls are set to ____ and ____ respectively.
Low, High
This synoptic indicates the air conditioning temperature controls are set to ____.
mid-position
An engine failure during climb, cruise, or descent will be indicated by ____.
the EICAS caution message ENG FAIL L or R
A red ENG FAIL on the PFD, accompanying voice annunciation, and Master Warning lights are displayed if an engine failure occurs ____.
between 65 knots and 6 knots prior to V1
On the 777-200ER, engine flameout protection is provided by an auto-relight function in the EEC. This function ____.
is activated when engine is at or below idle with the fuel control in Run and N3 above 35%
During the start, you will know the engines have stabilized at idle when the ____.
maximum start limit line (red) is no longer displayed on EGT
During engine start, which of the following parameters will Autostart NOT monitor and correct?
No oil pressure.
Prior to engine start, duct pressure may indicate less than ___ psi with the starter valve closed. Once the starter valve is open, the duct pressure should increase to a minimum of ___ psi.
20, 25
777/200ER) During an AUTOSTART, the First Officer moves the start selectors to START and then moves the Fuel Control Switches to RUN. The FO will monitor _____?
Oil pressure and temperature
During the start, both pilots notice that there is no oil pressure indication after the EGT increases. The Captain calls for the Aborted Engine Start checklist (QRC). What should be the next immediate action?
Per the QRC, the First Officer moves the Fuel Control Switch (affected side) to CUTOFF
