What would likely happen if compressor stall occurs in an engine?

1. The engine would perform optimally

2. The engine would shut down completely

3. Engine performance issues may arise

4. No effect on the engine

The correct answer is: Engine performance issues may arise

Compressor stall is a phenomenon that occurs when the airflow through the compressor becomes disrupted, leading to a loss of engine performance. When a stall occurs, it can cause various engine performance issues. These problems can manifest as a loss of thrust, fluctuations in engine power, or rough operation. The engine might still be operational, but it will not function at its optimal capacity due to the uneven airflow and pressure imbalances created by the stall condition. Understanding the ramifications of a compressor stall is crucial for aviation maintenance technicians, as it emphasizes the importance of monitoring engine performance and the potential for further complications. If not addressed, a compressor stall could lead to more severe issues, such as complete engine shutdown or damage over time, as components may experience excessive stress. In contrast, other options suggest outcomes that do not align with the typical effects a compressor stall has on engine operation. Therefore, recognizing that performance issues can arise during such a scenario is essential for anticipating and mitigating risks associated with engine stalls.
