Where is the APU emergency shut down located on the B777 and B737 aircraft?

The APU emergency shutdown switch on aircraft is designed for quick access in case of an emergency involving the Auxiliary Power Unit (APU). In the context of the Boeing 777 and Boeing 737, the emergency shutdown location on the AFT side of the nose gear is critical for the safety of ground personnel and the aircraft.

This location allows for efficient and safe access from outside the aircraft, enabling personnel to react quickly in the event of an APU malfunction or fire, minimizing the risk to both the crew and the aircraft.

Placement options such as the forward lotus hatch, under the right wing, or in the engine compartment would not provide the same level of timely and safe access. Those areas may pose operational hazards or complicate the emergency shutdown procedure, highlighting why the AFT side of the nose gear is the designated location for this important safety feature.
