Tech Flashcards
Throttle augmentation.
Compensates for slow response in throttle movements by deploying slats
Flap anti balloon
Alt hold prevents pitching movement on flap deploying
Therefore spoiler scheduleing prevents ballooning
Flight control surfaces
8 spoilers
2 outboard ailerons
8 slats
Two rudders
Two elevators
ALS
Alpha limit system
Prevents deep stall
Stops high angles of attack
PRCAH
Pitch rate command/attitude hold
Engages whilst airborne
Stabiliser
The horizontal Tailplane full movement
Single hydraulic failure
Effect spoilers by 25%
- degrades DLC
- small degradation of max speed brakes
- May effect roll performance
Fire detection system
Each engine and the APU
DC battery bus
Two loops with a FDCU
Both loops must be energised for MAster caution
1 means loop light only
Engine extinguisher
Halon 1301
A and B Extinguisher with 2 lines running into 1 engine on each wing
1 system on each wing
Fuel tank capacity
Non ER
Tank 1&4
37,760 each
Tank 2&3
52,640 each
ER
Tank 2&3 84,540
Uses central spare
Automatic fuel transfer
Whenever the inboard tanks have more than 38,000 pounds they automatically keep the outboard tanks full
Below this the outboard tank fill valve closes
Basic fuel tank system
Forward and aft fuel compartments
Booster pumps sit in forward engine feed box
Transfer pumps sit in the aft section of the tanks
Fuel is kept forward for Cof G
Malfunction of the FQC
MC calculates on last known quantities
Low fuel on WAP
Low fuel on total fuel
Less than 4,000 in tank
Less than 16,000 combined
Fuel quantity measurements reliable?
+- 5 degrees pitch attitudes
FQGS beyond -10 to +18
During tach descents up to 10,000 pounds error
MANF Drain
Manifold drain
Drain manifold of fuel and moves it to right inboard tanks
At what fuel quantities do the outboard/inboard fuel transfer pumps become ineffective
28,000 in
12,000 out
SCHD
Schedule on fuel pannel
Inboard tank unable to automatically transfer fuel forward from aft tank. Has to be done manually
FWD AFT
Fuel panel
Forward and aft boos pumps
Low captions illuminate at certain high nose pitch forward attitudes
SCHD
Man
Fuel management System
Allows manual transfer override
How is the aircraft refuelled?
Gravity - top of wing tanks
SPR - single point refuel (1,100gpm)
Defuel - 200 gpm
SPR panel
Single point refuelling panel
Located starboard behind the wheel well
Fuel higher level test
Shit of valve prevents fuel being added when tank is full. Can be preset if below max refuelling
Max fuel dump
6,700lbs per min
Automatically stops at 20,000lbs fuel
