Systems - Engines / Thrust Levers / Fuel Control Switches Flashcards
What will happen if the EEC detects a rapid N2 power reduction to less than idle RPM?
It will turn on both ignitors
How many valves must fuel pass through from the tank to the engine?
Spar and Engine
How many fuel pumps are involved in supplying fuel to the engine?
2 per tank and engine driven vacuum pump
What system powers the thrust reversers?
Respective HYD system
Is reverse thrust available when airborne?
No it is locked out
Explain how a maximum value is depicted on the EPR and N1 displays.
Red lines
What does the green carrot on the outside of the EPR or N1 graphic represent?
Reference target indication
How is the ground start limit EGT depicted on the EGT gauge?
Red
During normal start, what is indicated when this red radial disappears?
Completed engine start
What happens if the EGT start limit is exceeded?
The whole gauge turns red and boxed value remains recall
Can the auto throttles when engaged be overridden manually by the pilot?
Yes
Name 2 ways to disengage the auto throttles manually.
- Switch on levers
- A/T arm switch on MCP
Do the thrust levers have any direct mechanical connection to the EECs or TMCs?
No
At the beginning of the takeoff roll, how many TOGA switches must be pushed to get THR REF power?
One
What will happen if you do a rejected landing after touchdown and push TOGA to go around?
Nothing you must push the thrust levers up yourself to stow the speedbrake and disengage autobrakes
If inadvertently TOGA is pushed on an approach how do you terminate TOGA mode?
Above 400’ reselect another mode. Below 400’ disconnect the autopilot, cycle both F/D switches and reselect the approach mode
What happens when the fuel control switches are moved to RUN during the start cycle?
It gives the EEC control of the fuel valves and the engine starting process
When should the fuel control switches be moved to CUTOFF during an abnormal start?
- 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.
