PSA Airlines Canadair Regional Jet Systems (PSA-CRJ) Practice Exam

What does the absence of a starter cutout indicate during engine starting?

1. The engine is ready for takeoff

2. The starter is still engaged

3. The engine failed to start

4. The engine is in idle mode

The correct answer is: The starter is still engaged

The absence of a starter cutout during engine starting indicates that the starter is still engaged. In the context of the Canadair Regional Jet systems, the starter cutout is a critical safety feature designed to disconnect the starter from the engine once the engine reaches a specific speed or when successful ignition occurs. If there is no cutout, it suggests that either the engine has not reached the required speed or that the ignition has not occurred, preventing the starter from disengaging. This could lead to potential damage to the starter or the engine if it remains engaged for too long. Therefore, recognizing that the starter is still engaged is essential for proper engine operation and maintenance procedures.
