True or False: The engine exhaust area may extend up to 250ft from the back of the engine at idle.

The statement is true. Engine exhaust can indeed extend up to 250 feet from the back of the engine at idle, particularly for jet engines. This is an important safety consideration in ramp operations, as the heat and noise generated by jet engines can impact personnel and surrounding equipment. Understanding this fact helps ground crew members maintain a safe distance from operating aircraft while they are on the ramp.

In terms of context, while other options might suggest variability based on specific aircraft types, altitudes, or configurations, the general principle about idle engine exhaust and its considerable reach remains constant across most jet engines.
