PIQ EOCT Flashcards
Don't suck at flying
The APU and EPU supply electrical power to the ____ and ______ of the aircraft, respectively. (think opposite of the physical APU position)
Left and Right sides
The transformer / rectifiers perform the function of what? (think transforming something to something else)
Converting AC power to DC power.
When using the DC electrical system, the __________ configuration is the normal mode for operation.
Split-parallel
Which generator buses are the normal sources of power for the battery chargers? (the san diego chargers record this season)
1 and 4
Which of the following buses is always powered even if the battery switch is OFF?
Battery-direct buses
Which position of the avionics bus switch (AV BUS)
enables automatic load shedding when the aircraft is
on the ground with inadequate cooling? (would you want to waste brain bites on shedding or have it happen AUTOmatically?)
AUTO :)
Which component(s), during emergency/ backup system operations, converts DC power into AC power for the AC emergency bus? (think of what un-does the job of the transformer / rectifier?)
Static inverter
Power for the backup emergency system is provided by the what? (assume your generators shit the bed, what still has JUICE?)
The damn Aircraft batteries
Which of the following emergency/backup
system buses can be used to remove partial
power requirements from the batteries after
initial critical actions have been taken?
AC/DC Transfer Buses
What should be done if the battery bus fails?
Land as soon as possible
If a GEN OIL caution message appears on the WAP, the corrective action is to what? (so in theory you have a generator running with fucked up oil, what should you do?)
Turn the generator off
If all generators fail, what capability becomes inoperative with a subsequent failure of one of the remaining flight control computers (either FCC 1 or 4) or IRUs (1 or 4)?
Yaw damping
When performing the Electrical Fire and Smoke checklist (which seeks to identify and isolate the source of the smoke/fire), pause after doing what?
Pause after each step which de-powers a portion of the jet….
[you have to be able to act and observe the reaction of shutting down each portion of the moose to solve the problem]
The engine-driven hydraulic pumps provide continuous hydraulic pressure of ______ psi.
4,000 psi
The engine-driven hydraulic pumps are located
where? (bruhh where have the ENGINE DRIVEN pumps always been located since UPT?)
In the respective engine Accessory Gearbox
There are _______ engine driven hydraulic pump(s) per system, located on and driven by their respective engine accessory gearbox.
Two
The primary purpose of the _____ pump is to assist in landing gear retraction or cargo door/ramp closing in the event of No. 2 or 3 engine loss.
Transfer
The RAT, located in the right landing gear pod, develops enough pressure to control the aircraft
for what phase of flight?
All engine-out emergencies
During ground operations, you have been using
hydraulic system 1 without any engines running. The
MASTER CAUTION light comes on as well as the
HYD cue light and a LOW in the Sys 1 Aux pump
switch light. You should conclude that you have what? (the key word here is w/o engines running… which pump do we use w/o engines on the ground?
Failure of AUX pump 1
Hydraulic transfer pump automatic shut off may be
caused by what?
Low quantity condition in system 2 or 3
If the hydraulic system pressure increases above 4200 psi, depressurize the pumps how?
One at a time,
The primary source of oxygen for the crew system is one _______ liquid oxygen converter(s).
25-Liter
The oxygen cross-feed switch is used to do what?
Connect the crew and passenger oxygen systems
The CREW OXY LOW warning illuminating on the WAP indicates the oxygen quantity or pressure is _______ or _______?
quantity remaining is less than 5 liters or
supply pressure is below 60 +/- 5 psi.
