After using the EFCO switch to shut down the engine, what should the engineer do next in the engine shut down process?

• A. Inspect the engine for leaks
• B. Reset the engine control switch
• C. Wait two minutes
• D. Notify maintenance

Answer: (C)

After the EFCO switch shuts the engine down, the next step is to wait two minutes. This short cooldown period lets the engine wind down and any residual fuel in the lines drain safely. It reduces the risk of heat or pressure complications if you move to the next actions and provides a stable condition before proceeding with follow-up checks or maintenance steps.
