Recurrent systems exam Flashcards
When is Go-Around armed?
When flaps are extended
When G/S is captured
What automatic switching will occur if you start the APU with the primary external source powering the right main bus and the secondary external source powering the left main bus?
The APU then powers the left main bus and the primary external source continues to power the right main bus.
T or F: The PMGs in the Backup generators are only turned on when the Backup generators are activated?
False
What is the electrical configuration during autoland?
The busses isolate to allow three independent sources to power the three autopilots
If below 1500ft agl with LOC and G/S captured, how do you disconnect Approach Mode w/o engaging TO/GA?
Disengage the auto-pilot and turn both F/D switches off, then back on
What provides DC power on this airplane?
Four transformer-rectifier units (TRUs)
What is the primary electrical power source for the flight control DC electrical system?
Permanent magnet generators (PMGs)
You are having a bad day and are down to the electrical generator on the RAT. The RAT then experiences high hydraulic demand and then ELMS load sheds the electrical part of the RAT. Does the Captain’s flight instrument remain powered?
Yes, the Captain’s FLT INST bus will remain powered from the main battery.
What does LAND 2 on your PFD with NO LAND 3 on your EICAS mean?
The autoland system does not have redundancy for triple channel autoland.
The RAT is deployed automatically if?
Both AC transfer busses lose power in flight.
On your FMA you have two green TO/GA annunciations, what does this mean?
Takeoff/go0around is engaged for roll and pitch.
What thrust reference mode display indicates an assumed temperature derated takeoff thrust condition is selected?
D-TO
When does the EEC select approach idle?
Flaps are commanded to 25 or greater.
What malfunction, during ground start, will cause the autostart system to abort the start?
Hot start
When is continuous ignition automatically provided?
The flap lever is out of the UP position, or engine anti-ice is on.
On your FMA you have HOLD, TO/GO, TO/GO, which statement is true?
If the trust levers are manually positioned, the autothrottle with not reposition them to T/O thrust.
When does the engine failure alert system provide a red ENG FAIL annunciation on the PFD if actual thrust is less than commanded thrust?
During takeoff with airspeed between 65 knots and 6 knots prior to V1.
When is the APU operating in the attended mode?
When either engine is running or starting, or when the airplane is in flight.
