Question 11

What protections do the FADEC provide?

Answer 11

On ground only:
- Hot Start
- Hung Start
- No lightoff

Other:
- N2 Overspeed (> 102%)
- Overtemperature in flight (various limits depending on engine phase)

Question 12

Why the start stop selector must be moved to stop in case of hot start?

Answer 12

During engine start if the ITT reaches its limit the FADEC automatically
shuts off the fuel flow aborting the start sequence. In this case the start
control valve is not automatically closed. Pilot intervention is needed to
close the SCV by selecting the START/STOP switch to STOP.

Question 13

Flat rate temperature over which the engine power starts to decrease

Answer 13

ISA+15
