B_FS 7. Engines, APU

1. Question

Oil pressure at or below red line
during takeoff from 80 knots to 400 feet RA
during landing below 200 feet RA until 30 seconds after touchdown
during periods when blinking is inhibited, alerts illuminate steady

2. Question

Secondary engine indications에 표시되지 않는 계기는?

Fuel flow
oil pressure
EGT
oil temp

3. Question

Overhead panel의 ENG CONTROL light on되었다. 틀린 것은?

In flight – on
On Ground below 80 kts prior to takeoff
approximately 30 seconds after touchdown on Ground
engine is operating and airplane on ground and below 80 kts prior to takeoff

4. Question

Reverse thrust lever 사용 시 Idle position에 몇 % Deploy 될 때 까지 block되는가?

50 %
55 %
60 %
65 %

5. Question

APU cooling Period와 Inlet door에 설명으로 맞는 것은?

50 second / APU inlet door automatically closes after shutdown
50 second / APU inlet door automatically closes after APU switch OFF
60 second / APU inlet door automatically closes after APU switch OFF
60 second / APU inlet door automatically closes after shutdown

6. Question

EEC에 대하여 잘못 설명한 것은?

EEC는 Command N1과 Actual N1을 비교하여 fuel을 조절, Actual N1과 Command N1을 같게 한다.
Electronic Engine Control의 약자이며 Normal Mode, Alternate Mode, Manual Mode로 구분된다.
EEC는 자동으로 Thrust Lever를 전방(Forward) 및 후방(Rverse) Thrust를 조절한다.
Engine Panel에 있는 스위치를 통해 Manual로 전환이 가능하다.

7. Question

EEC가 Power를 받지 않으면 나오지 않는 indication이 아닌 것은?

EGT
N1
N2
Oil Quantity

8. Question

Engine starting 중 EGT가 start limit를 초과할 때 나타나는 현상이 아닌 것은?

The EEC automatically turn off the ignition
The EEC automatically shut off fuel to the engine
The EGT display, both box and dial, turn red
Following engine shut down, the EGT box turns amber to remind the crew of the exceedance

9. Question

Engine starting 중 Start lever를 IDLE에 위치시키면 작동되는 구성품이 아닌 것은?

the fuel valves on the wing spar
the fuel valves on engine
Ignition System
Engine Starter

10. Question

Thrust reverser system을 작동시키는 power source는?

해당 engine에서 생산되는 pneumatic power
다른 engine에서 생산되는 pneumatic power
Hydraulic power
해당 engine의 oil pressure

11. Question

If uncommanded movement of the Reverser is made or storage is not complete following condition will occur :

Electro – Mechanical Lock
Isolation Valve Open
STBY HYD activation
Control Valve (deploy)

12. Question

APU를 On 했으나 작동하지 않을 때 확인하지 않아도 되는 것?

Battery Switch On.
No1 Fuel Tank(FWD or AFT) Pump switch On
APU Fire Switch IN
APU Ground Control Lever IN.

13. Question

APU switch to OFF, closes the APU bleed air valve일 때 APU shutdown에 관하여 옳은 것은?

Closes the APU bleed air valve and illuminate the APU GEN OFF BUS light
The fuel valve does not close, the FAULT light will illuminate after approximately 30 seconds
The fuel valve does not close, the FAULT light will illuminate after approximately 60 seconds
The fuel valve does not close, the FAULT light will extinguish

14. Question

다음 중 APU Low oil Pressure Amber light가 illuminate될 조건 중 틀린 것은 무엇인가?

during start until the APU oil pressure is LOW
oil pressure is low causing an automatic shutdown (after start cycle is complete)
if light is illuminated when APU switch is placed to OFF, light extinguishes after 5 minutes
light is disarmed when APU switch is in OFF position

15. Question

다음 APU starting에 관한 내용 중 틀린 것은 무엇인가?

The automatic start sequence begins by moving the APU switch momentarily to START more than 3 seconds
When the APU is ready to accept a bleed air or electrical load the APU GEN OFF BUS light illuminates
This initiates opening of the air inlet door
When the APU inlet door reaches the full open position the start sequence begins

16. Question

다음 중 APU starting에 관한 설명 중 틀린 것은?

APU switch를 START 위치에 momentarily 위치시킨다
APU RPM이 적절한 speed가 되면 ignition과 fuel supply가 시작된다
만약 start가 fail되거나 start cycle 끝에 GEN OFF BUS light가 illuminate 되지 않으면 FAULT light가 illuminate 된다
APU inlet door가 close 되면 start sequence가 시작된다

17. Question

다음 중 EGT indication이 Red로 지시되는 것은 어떤 경우인가?

start limit exceeded
normal operating range
minimum takeoff limit
color change inhibited for up to 5 minutes during takeoff or go–around

18. Question

다음 APU low oil pressure light가 illuminate되는 조건 중 틀린 것은 무엇인가?

if light is illuminated when APU switch is placed to OFF, light extinguishes after 10 minutes
light is disarmed when APU switch is in OFF position
during start until the APU oil pressure is normal
oil pressure is low causing an automatic shutdown (after start cycle is complete)
