Aircraft systems and instrumentsQuestion 644 of 934

What do FADEC systems eliminate the need for?

  1. The fuel tanks, fuel pumps, and fuel filters
  2. Magnetos, carburetor heat, and mixture controls
  3. The propeller governor and the crankshaft
  4. The oil pump, oil cooler, and cooling fins
Show answer

Correct answer: Magnetos, carburetor heat, and mixture controls

A single throttle lever is typical of an aircraft with FADEC. The pilot does not need to control the mixture.
