What is the safe exhaust distance for engine/APU on a C-5?

The safe exhaust distance for the engine/APU on a C-5 is recognized as a critical safety measure to ensure that personnel and equipment are not adversely affected by exhaust emissions and heat. Keeping a distance of within 50 feet minimizes the risks of being exposed to hazardous gases, heat, and potential damage to nearby equipment or personnel.

The distance of 50 feet is recommended based on the engineering and safety standards that take into account the intensity of the engine exhaust, which includes both the temperature and the potential for harmful emissions. This level of distance provides a buffer for effective ventilation and ensures operational safety during maintenance, fuel loading, or ground operations.

Longer distances, such as 100 feet or beyond, may provide additional safety but are often not necessary for the operational parameters established for the C-5. Maintaining a 50-foot distance balances safety with operational efficiency, allowing for close access without compromising the wellbeing of those around the aircraft.
