hot start, no ignition, stalled start.
FADEC has three idle modes including:
modulated idle, approach idle & reverse idle.
Automatic and manual starts are identical in all respects except pilot action is required to manually open
the start valve by selecting the ENG MAN START pushbutton ON.
FALSE
The ignition system:
consists of two independent circuits designated A & B which are alternated by FADEC at each
engine autostart.

5 detents – TOGA, FLX/MCT, CLimb, IDLE, MAX REVerse
Continuous ignition is provided automatically when the Engine Mode selector is in the NORM
position in all of the following EXCEPT:
Leading edge slats are retracted.
During automatic engine start, selecting an Engine Master switch ON causes:
the LP fuel valve to open and the HP valve opens at a preset N2.
Which statement about the APU is true?
The APU has a dedicated fuel pump that supplies fuel from the left fuel manifold in the event that
tank boost pumps are not operating.
The Electronic Instrument System presents data on _____ identical display units.
