How does the EEC assist during a flameout?

1. Increases fuel flow to all engines

2. Activates both igniters automatically

3. Engages thrust reversers

4. Raises thrust levels immediately

The correct answer is: Activates both igniters automatically

The answer is correct because the Engine Electronic Control (EEC) plays a crucial role in enhancing aircraft safety during critical situations such as a flameout, which occurs when an engine's combustion process is disrupted. When a flameout happens, the EEC automatically activates both igniters to attempt to relight the flame in the affected engine. This action is vital for restoring engine power and maintaining control of the aircraft, particularly during flight when engine performance is essential for safe operation. The other options do not accurately describe the EEC's function during a flameout. For instance, increasing fuel flow to all engines would not be a suitable response, as it could exacerbate the situation by flooding an already compromised engine. Engaging thrust reversers is generally associated with landing procedures rather than addressing flameouts and is not relevant in this critical phase. Similarly, raising thrust levels immediately could lead to instability or further engine issues, which is not the EEC's primary function when dealing with a flameout. Thus, the activation of both igniters is the precise and appropriate response to mitigate the risks associated with a flameout.
