FAA Powerplant Written Practice Test

Which component is primarily responsible for the electronic management of engine fuel flow?

1. A Power lever

2. B Electronic Engine Control (EEC)

3. C Turbocharger

4. D Fuel pump

The correct answer is: B Electronic Engine Control (EEC)

The Electronic Engine Control (EEC) is primarily responsible for the electronic management of engine fuel flow. It acts as the brain of the engine management system, processing data from various sensors to optimize fuel flow and ensure efficient engine performance. The EEC uses inputs from a variety of parameters, including engine speed, temperature, pressure, and other conditions, to make real-time adjustments to the fuel flow. This capability allows the system to maintain optimal air-fuel ratios under varying operating conditions, improving overall performance, fuel economy, and emissions control. This precision control is crucial for modern jet engines, where efficiency and reliability are paramount. The EEC can also manage other engine parameters, such as ignition timing and engine throttling, ensuring that the engine operates within safe limits while delivering the necessary thrust. Other components like the power lever and fuel pump play roles in the operation of the engine, but they do not provide the comprehensive electronic management of fuel flow that the EEC does. The power lever primarily serves as a pilot control for engine thrust, while the fuel pump's function is to deliver fuel to the engine rather than manage the flow electronically. The turbocharger is designed to enhance engine performance by forcing more air into the combustion chamber but does not directly manage fuel
