Systems - Engines / Thrust Levers / Fuel Control Switches

Question 1

What will happen if the EEC detects a rapid N2 power reduction to less than idle RPM?

Answer 1

It will turn on both ignitors

Question 2

How many valves must fuel pass through from the tank to the engine?

Answer 2

Spar and Engine

Question 3

How many fuel pumps are involved in supplying fuel to the engine?

Answer 3

2 per tank and engine driven vacuum pump

Question 4

What system powers the thrust reversers?

Answer 4

Respective HYD system

Question 5

Is reverse thrust available when airborne?

Answer 5

No it is locked out

Question 6

Explain how a maximum value is depicted on the EPR and N1 displays.

Answer 6

Red lines

Question 7

What does the green carrot on the outside of the EPR or N1 graphic represent?

Answer 7

Reference target indication

Question 8

How is the ground start limit EGT depicted on the EGT gauge?

Answer 8

Red

Question 9

During normal start, what is indicated when this red radial disappears?

Answer 9

Completed engine start

Question 10

What happens if the EGT start limit is exceeded?

Answer 10

The whole gauge turns red and boxed value remains recall

Question 11

Can the auto throttles when engaged be overridden manually by the pilot?

Answer 11

Yes

Question 12

Name 2 ways to disengage the auto throttles manually.

Answer 12

1. Switch on levers
2. A/T arm switch on MCP

Question 13

Do the thrust levers have any direct mechanical connection to the EECs or TMCs?

Answer 13

No

Question 14

At the beginning of the takeoff roll, how many TOGA switches must be pushed to get THR REF power?

Answer 14

One

Question 15

What will happen if you do a rejected landing after touchdown and push TOGA to go around?

Answer 15

Nothing you must push the thrust levers up yourself to stow the speedbrake and disengage autobrakes

Question 16

If inadvertently TOGA is pushed on an approach how do you terminate TOGA mode?

Answer 16

Above 400’ reselect another mode. Below 400’ disconnect the autopilot, cycle both F/D switches and reselect the approach mode

Question 17

What happens when the fuel control switches are moved to RUN during the start cycle?

Answer 17

It gives the EEC control of the fuel valves and the engine starting process

Question 18

When should the fuel control switches be moved to CUTOFF during an abnormal start?

Answer 18

• If autostart is active whenever the EICAS MSG appears, or engine parameter that is not monitored is exceeded or absent.
• If manual start then during any approach to a starting limit.
