True or False: The PEL checklist is unnecessary if the engine is still operational.

The statement that the PEL (Precautionary Engine-Loss) checklist is unnecessary if the engine is still operational is false. The PEL checklist is an essential tool in managing engine-out scenarios, even when the engine is functioning normally. Its purpose is to prepare the pilot for a potential engine failure by ensuring all necessary steps are taken to maintain control of the aircraft and to mitigate risks.

Using the PEL checklist while the engine is operational helps reinforce standard procedures and keeps the pilot prepared for unexpected situations. It ensures that critical tasks are completed, such as altitude management, situational awareness, and readiness to respond should the engine fail. Relying solely on the engine's current performance can lead to complacency and a lack of preparation for emergencies, which is counterproductive to safe flight operations. Thus, consistently following the PEL checklist is a best practice in flight training and real-world scenarios.
