OFP Knowledge Questions Flashcards
During Take-off, with LNAV and VNAV armed, at what altitude will they engage?
LNAV - 50’ RA;
VNAV - 400’ above runway elevation.
With cold soaked fuel, up to what temperature can frost occur on the upper wings?
20Deg C
“ELT ON” is displayed on EICAS. Can the fuselage mounted ELT be deactivated?
Yes. If the EICAS alert message “ELT ON” is displayed the transmitter is activated. The ELT can be deactivated by placing the ELT switch to RESET momentarily then ARMED.
The door 4 or 5 upper Crew rest area alert horn sounds continuously. What has occurred?
Airplane decompression occurs.
Is full automatic operation of cabin altitude control possible with one outflow valve not operating?
Yes. Full automatic operation of cabin altitude is possible with one outflow valve operating automatically and the other outflow valve not operating.
If a primary electrical power failure occurs, the main battery can power the standby electrical system for how long?
The main battery can power the standby system for a minimum of 10 minutes.
What happens if the ADIRU is switched ‘OFF’ in flight?
Both PFDs will blank.
What is the altitude source for transponder altitude reporting when the ALT SOURCE selector is in the NORM position?
ADIRU
TRUE or FALSE?
When required, the Left Backup Power Generator will energize the Left Transfer Bus only and the Right Backup Power Generator will power the Right Transfer Bus only.
FALSE
If both IDGs and APU GEN are inoperative the backup GEN powers what essential systems?
TCAS, SATCOM, Position lights
During fuel jettison, if the auto jettison system fails:
The fuel jettison will stop at approx. 5200 kg or 3800 kg (as installed) in each main tank.
Which statement is true about Fuel Jettison is correct?
A. The nozzles cannot open on the ground, regardless of switch positions.
B. If the center tank override/jettison pumps are off, center tank fuel also jettisons.
C. Jettison automatically stops and the system shuts off the main tank jettison pumps and opens the center tank jettison isolation valves
D. Push in and rotate the FUEL TO REMAIN selector to manually decrease or increase the TO REMAIN quantity.
A. The nozzles cannot open on the ground, regardless of switch positions.
When is the EICAS advisory message FUEL PUMP CENTER L displayed?
When the centre tank fuel pump is ON and the pump output pressure is low.
What happens to jettison time as altitude increases?
It increases.
TRUE or FALSE?
If the Ram Air Turbine is deployed and is unable to maintain RPM, the RAT generator electrical load is shed and hydraulic power has priority over electrical power.
TRUE
What are the actions if the crew decides to discontinue an approach instead of executing the normal go around procedure?
The selection of TO/GA above the selected MCP altitude results in an unrestricted climb. Therefore, time permitting the crew shall assess the position of the aircraft before a go-around is initiated.
The crew may decide not to execute the normal Go-Around and Missed Approach procedure as prescribed in the FCOM/QRH with the following considerations:
- both pilots agree on the proper AFDS mode selections to discontinue the approach;
- the PF announces when initiating the discontinued approach;
- notify ATC and obtain a modified clearance, as needed;
- verify that the missed approach route is tracked and the aircraft is climbing or descending to the published or cleared missed approach altitude.
What are the PF actions (if necessary) for a nose high UPRT recovery and what is the Warning associated with the recovery?
- Recognize and confirm the developing situation
- Disengage autopilot
- Disconnect autothrottle
- Recover
- Apply nose down elevator. Apply as much elevator as needed to obtain a nose down pitch rate;
- Apply appropriate nose down stabilizer trim*;
- Reduce thrust;
- Roll (adjust bank angle) to obtain a nose down pitch rate*.
- Complete the recovery:
- When approaching the horizon, roll to wings level;
- Check airspeed and adjust thrust;
- Establish pitch attitude.
WARNING: * Excessive use of pitch trim or rudder can aggravate an upset, result in loss of control, or result in high structure loads
How many quick donning oxygen masks are installed on the flight deck?
One is located at each crew station on the flight deck.
Passenger oxygen masks will automatically deploy at approximately what cabin altitude?
13500 feet AMSL
After flight crew oxygen is no longer required what is the required procedure to restore boom/hand microphone operations?
Close the left hand oxygen compartment door, then push the RESET/TEST switch to restore normal boom microphone operation.
What does ENG AUTOSTART OFF represent on the EICAS?
The Autostart switch is OFF.
In the CUTOFF position, fuel flow to the combustion section of the engine is prevented by the spar valve and______?
The engine fuel valve.
Following an engine failure on takeoff the maximum thrust available for takeoff is certified for a period of how long?
10 minutes.
In Normal Mode when will the Ailerons be ‘locked out’?
During High-speed flight.
