B-747 Oral Question Bank Review
Air Systems - ✔ ✔
When does the equipment cooling system configure for flight - ✔ ✔
One or more engines on each wing is operating
When is warm equipment cooling air ducted overboard on the ground -
✔ ✔ Engines not operating
,Equipment cooling selector in NORM
Ambient temperature moderate or high
Equipment cooling provides cooling air for what compartment and
systems - ✔ ✔ Flight deck equipment
Electrical and equipment racks (E & E bay)
How can you manually configure the equipment cooling system for
flight - ✔ ✔ Positioning the Equipment Cooling Selector to STBY
What is the function of the Lower Love Cargo Conditioned Air Flow Rate
Selector (LLCCAFR) - ✔ ✔ Provides forward and aft lobe cargo air
conditioning.
What happens if a pack temperature controller (PTC) detects a fault in a
pack channel - ✔ ✔ Control of the respective pack switches to the
other PTC
How many pack temperature controllers (PTC) are provided - ✔ ✔
Two - A and B
When in the descent mode, will the cabin altitude controllers program
a positive or a negative pressurization at touchdown - ✔ ✔ Small
positive pressurization at touchdown
What action would allow manual operation of the pressurization
system - ✔ ✔ Turn both Outflow Manual switches to ON
,-All automatic cabin altitude control functions are now bypassed
When does the cabin altitude controller switch from controllers (i.e. A
to B) - ✔ ✔ Automatically selects A or B on alternate flights
Will switch automatically if the other fails
How many cabin altitude controllers are provided - ✔ ✔ Two
controllers A and B
-Each controller controls both outflow valves
How can you gain manual control of the landing altitude - ✔ ✔ By
pushing the LDG ALT switch
Additional info
-landing altitude set by rotating landing altitude selector
-landing altitude followed by MAN displayed on primary EICAS
-the EI AS advisory message LANDING ALTITUDE is displayed
Can either outflow valve maintain cabin altitude - ✔ ✔ Yes
-One pack is selected off to ensure cabin doors may be opened
regardless of the position of the outflow valves if an emergency
evacuation is required immediately after landing.

✔ Thrust limiting
Maintains constant thrust
Over-speed protection
What occurs in the auto-throttle system when any EEC control is
switched to alternate mode - ✔ ✔ The auto-throttles disconnect,
but can be.reconnected when all EEC's have been switched to alternate
mode
What EEC normal mode protection feature is not available in EEC
Alternate mode - ✔ ✔ Thrust limiting at maximum N1
(Maximum thrust can be achieved prior to thrust lever position at full
forward)
When does the EEC select approach idle - ✔ ✔ Flaps in a landing
position
Continuous ignition switch is ON
