Power Plants

Question 1

Engine

Answer 1

F414-GE-400 low bypass, axial flow, dual-spool turbofan engine of modular construction with afterburner

Question 2

3 modes of APU

Answer 2

GMM, ECS, MES

Question 3

IFR

Answer 3

Take fuel while in-flight, forward fuselage

Question 4

Aircraft fuel storage

Answer 4

Four in internal fuselage tanks, two wing, up to five external

Question 5

Foam-lined wing tanks

Answer 5

Self-seal holes or damage, decreasing fire and explosion hazards

Question 6

APU
AMAD
Secondary Power Compressed Air

Answer 6

• gas turbine engine supplying air for ECS operation and MES and GMM through AMADs
• Two gearboxes, mechanically connected to engine by PTS. Pneumatically connected to APU through ATS. AMAD transmits power to engine
• Provides pneumatic power for operating air turbine starter or ECS, provided by APU or engine bleed air

Question 7

Ignitions

Answer 7

Automatic, intermittent duty, AC powered, capacitor discharge system. Remains energized until rpm is 54% or greater

Question 8

Lubrication

Answer 8

Dry sump

Question 9

Main fuel

Answer 9

governs correct main fuel flow IDLE-MIL

Question 10

Afterburner fuel

Answer 10

Governs correct AB fuel flow from AB start to MAX

Question 11

VEN

Answer 11

Changes pressure output to provide thrust

Question 12

Variable Geometry

Answer 12

Fan variable geometry and Compressor Variable Geometry

Question 13

Anti-Icing

Answer 13

Anti-ice flow to engine front frame center body and inlet device

Question 14

FADEC

Answer 14

Receives aircraft and engine sensor information and determines appropriate engine scheduling to operate the engine

Question 15

Throttle

Answer 15

Fly-by-wires system (no mechanical connections) commands and signals sent to and received from FADEC

Question 16

Refuel/defuel

Answer 16

manifold with a single point ground or in-flight input and outlet in each fuel tank. Door 8

Question 17

CG

Answer 17

Transferring fuel between tanks to keep aircraft balanced

Question 18

Hot fuel recirculation

Answer 18

fuel absorbs heat from liquid cooling systems, AMAD oil and hydraulic fluid to keep cool and maintains fuel delivery temp to engine and cools FADEC

Question 19

Fuel pressurization and vent

Answer 19

Maintain positive pressure on fuel in all tanks and vents fuel vapors overboard

Question 20

Fuel quantity gauging

Answer 20

Fuel quantity in each tanks

Question 21

AMAD components

Answer 21

Drive fuel boost/motive fuel pump and electrical generator and 3000/5000 psi hydraulic pump

Question 22

Safety precautions

Answer 22

Proper PPE maintain 9ft radius from intakes and 25 ft at MIL or MAX

Question 23

Fueling and defueling precautions

Answer 23

Must not be done within 100 feet of operating radio or radar or 300 ft of ground radar. Must wear goggles and watch gauges for overflow
