Final Answer:
The statement 'The air turbine starter cannot be engaged when the engine is rotating.' is True because The air turbine starter cannot be engaged while the engine is already rotating due to safety mechanisms in place to prevent damage caused by the simultaneous operation of the starter and the rotating engine components.
Step-by-step explanation:
The air turbine starter is an aviation component used to initiate the starting sequence of aircraft engines. It operates by providing compressed air to start the engine. However, safety mechanisms are incorporated into the starter system to prevent the starter from engaging while the engine is already in motion. Attempting to engage the starter while the engine is rotating could result in severe damage to both the starter and the engine components.
When an aircraft engine is already rotating, it indicates that the engine is in motion or running. Engaging the starter at this point could cause a clash between the starter and the rotating engine components, leading to catastrophic consequences such as gear damage, excessive wear, or even engine failure. As a safety measure, the air turbine starter is designed with interlocks or safety features that prevent its engagement while the engine is already in operation.
The inability to engage the air turbine starter while the engine is rotating is a critical safety precaution in aviation maintenance and operation. This safety measure ensures the protection of both the starter system and the engine, preventing potential damage and ensuring the overall safety and reliability of the aircraft's propulsion system.
