A320 Master Question Bank Study Guide Flashcards
(191 cards)
The engine generators and APU generator are rated at ____ KVA maximum continuous load
90
The normal priority for supplying electrical power to the AC buses is
engine generators, external power, APU
The BATTERY BUS is normally powered by
DC bus 1 through a DC tie contactor
With total AC power loss, and airspeed above 50 KTS, an inverter is connected to the hOT BATTERY BUS and supplies AC power to the:
AC ESS bus
An AC ESS Feed switch located on the overhead panel shifts the power source for the AC ESS bus from:
AC Bus 1 to AC bus 2
When the aircraft airspeed is above 100 KTS, which AC bus can be powered by the emergency generator?
AC ESS bus
The FASTEN SEAT BELT, NO SMOKING, and EXIT signs come on automatically when the cabin
altitude exceeds_______ feet, regardless of the respective switch position.
11,300’
Do not press the IDG DISCONNECT switch for longer than approximately______ seconds to prevent
damage to the disconnect mechanism.

The BAT pushbutton FAULT indication will illuminate when:
the charging current is outside its limits.
The IDG pushbutton FAULT indication will illuminate to indicate:
a. an IDG oil overheat.
b. IDG low oil pressure.
c. IDG low oil level.
d. either A or B (CORRECT!)
e. either A or C
If one generator exceeds 100% of its rated output:
the galley pushbutton FAULT light will illuminate.
On the A320, when operating with a single engine-driven generator on the ground or a single
generator in flight:
the main galley buses and in-seat power supplies are shed automatically.
The RAT & EMER GEN indicator on the EMER ELEC PWR panel illuminates a red FAULT
indication when:
AC BUSES 1 & 2 are not powered and the emergency generator is not supplying electrical power.
If avionics smoke is detected when the GEN 1 LINE pushbutton on the EMER ELEC PWR panel is
selected OFF:
GEN 1 is completely isolated from the aircraft except for supplying one fuel pump in each wing tank.
Engine fire detection sensors are installed in all of the following areas EXCEPT:
a. the fuel/oil heat exchanger (CORRECT!)
b. the pylon nacelle.
c. the engine core.
d. the fan section.
Each engine fire detection system consists of:
two loops with three heat sensing elements each.
If both engine fire loops fail within ______ seconds of each other, a _____ will occur.
5 / FIRE warning
If any component of the fire detection system fails:
the ECAM will issue appropriate messages(s).
If there is an APU fire in flight, the APU:
must be shut down manually and the fire bottle will discharged manually.
Fire protection for the forward and aft cargo compartments includes:
one extinguisher bottle which can be discharged to either compartment.
The engine fire extinguisher squib is armed when:
the ENG FIRE pushbutton is pushed and released.
CARGO SMOKE indicator will illuminate SMOKE in red when:
both of the two channels of the detection system detect smoke.
When the APU FIRE pushbutton is pushed and released, the:
APU bleed and crossbleed valves are closed.
A DISCH light on either the ENGINE or APU AGENT pushbutton indicates:
the extinguisher bottle has lost pressure.
