A

4,700, 39.45°c

32
Q

What does PMA Power and When?

A
  • Igniters, NG > 14%
  • FADEC, NG > 40%
33
Q

FADEC atmpts auto relight until NG

A

<56%, then FADECs Cut Fuel

34
Q

What does Start Switch to STOP do?

A
  • Shuts of Fuel to the engine
  • Turns off respective boost pump
  • NAC SOV Closed (if in Auto)
  • Closes Start Valve, IF starting
  • Deenergizes Ignition, IF starting
35
Q

What does Start Switch to RUN do?

A
  • Energizes Respective Boost Pump
  • NAC SOV Open
36
Q

Why NG 0 for 30” before Engine Start?

A

allows the NG Overspeed Circuit to be check

37
Q

What ACAWS is Expected with an Air Start?

A
  • PROP “X” NO 119% PROTECT caution

- FADEC May not perform Propeller Overspeed Circuit check. Follow Crew Actions in QRH

38
Q

When Exiting Hotel Mode, what may happen when unfeathering one propeller at a time.

A

MC shuts down the engine because HP increases without power lever movement. Engine restart is permissible.

39
