Question

When does the FADEC command a higher engine idle speed?

Answer 1

FADEC commands a higher engine idle speed in certain situations such as when the engine is cold or when additional power is required for systems.

Step-by-step explanation:

FADEC (Full Authority Digital Engine Control) commands a higher engine idle speed in certain situations such as when the engine is cold, to ensure a smooth start and prevent stalling. In cold weather, FADEC increases the idle speed to compensate for the decreased engine performance. FADEC may also command a higher idle speed when the engine is required to provide additional power for systems such as the hydraulic pump or the air conditioning.
