The main engine must be secured if for any reason the main engine turbine rotors cannot be rotated within how many minutes?

The main engine must be secured if for any reason the main engine turbine rotors cannot be rotated within how many minutes?

• A. 3 minutes
• B. 5 minutes
• C. 10 minutes
• D. 15 minutes

Answer: (B)

The correct answer is based on the operational guidelines for securing a main engine when turbine rotors cannot be rotated. It is critical to ensure that the main engine is secured within 5 minutes if the turbine rotors are unresponsive. This time frame is established to prevent potential damage to the turbine and associated components that may occur due to overheating or mechanical stresses if the rotors are stuck. Ensuring the rotors can rotate is essential for maintaining the operational integrity of the propulsion system. If the turbine rotors are not rotating as expected within this brief window, it indicates a significant issue that could escalate quickly. Hence, the protocol is designed to mandate immediate action to prevent further complications, emphasizing the importance of quick detection and response in maintaining machinery safety and reliability.
