A

20ft in front of intake and 35ft wide by 80ft length area from the engine exhaust

2
Q

Engine danger area - during max power behind exhaust

A

70ft wide by 150ft in length

3
Q

Engine danger area - APU noise restriction

A

75ft radius around the AC for 2 hours with no earplugs (non if earplugs)

4
Q

Engines

A

2 Rolls Royce 611-8 Tay engines, axial flow, medium bypass ratio, turbofan with 13,850 lbs of thrust at sea level.

5
Q

Fan location and function

A

front of the engine

2 Air streams- one bypass around the engine core and one through

6
Q

1st Compressor section

A

3 stage LP compressor, it cools certain parts of the engine and pressurizes engine oil seals

7
Q

2nd compressor section

A

12 stage HP compressor, moves air to the combustion section

8
Q

1st Turbine

A

Drives the HP compressor

9
Q

2nd Turbine

A

Drives the LP compressor

10
Q

Exhaust

A

creates thrust to propel the AC

11
Q

power levers location and function

A

Located on the center control pedestal.

It controls engine thrust.

12
Q

Thrust Reversers location and function

A

Located on rear of engine assembly.

slows AC when landing

13
Q

Engine Fuel System-

A

controls fuel flow

14
Q

Oil System-

A

A DRY SUMP system with oil stored in a tank installed on L side of engine.

Lubricates bearings, gears.

15
Q

EICAS location

A

middle instrument panel on display units 3 and 4.

16
Q

Engine Indication System EICAS Function

A

Displays Engine Pressure Ratio (ERP), LP and HP Tachometer, turbine gas temperature, fuel flow, oil pressure, oil temp, engine vibration monitoring, engine fuel temp, fuel quantity and hydraulic pressure.

17
Q

Engine vibration monitor (EVM)-

A

tells crew of impending failure (vibration has reached max allowance)

18
Q

Fuel Hopper location and capacity

Flapper Valves?
Boost pump?

A

The space between the centerline rib outboard to wings first structural rib.

190 us gallons capacity.

Fuel pours into hoppers via flapper valves preventing fuel back into wings during turning.

Fuel boost pump pumps fuel to the engines

19
Q

Fuel Ejector Pump-

A

makes sure that fuel hopper remains full. It gets fuel from wing to hopper.

20
Q

Boost pumps location, output and psi

A

Mounted outside on the back wall of the fuel tanks in the main landing gear wheel well,

OUTPUT OF 8000 LBS PER HOUR AT 22 PSI.

21
Q

Bleed Air

A

Pneumatics system is to provide a common manifold (bleed air manifold).

Hot compressed air for anti icing, pressurization, and air conditioning

22
Q

Auxiliary Power Unit function

A

Provides power for ground maintenance. Cools/heats a/c without starting the engine.

23
Q

Auxiliary Power Unit during flight

A

used as back up electrical power supply

24
Q

Auxiliary Power Unit during altitude below 30,000 feet

A

Assist in air starting an engine of the aircraft.

25
Q

Auxiliary Power Unit location

A

below the right engine pylon

26
Q

How many HP Fuel Cocks? Location and Function

A
  1. lower center pedestal below power levers. controls fuel to the engine.
