How is a "hot load" different from a "cold load"?

A hot load specifically refers to the process of loading troops or equipment onto a helicopter while the aircraft is in operation and has its engines running. This method is typically used in situations where time is critical, and the helicopter needs to quickly take off after loading. The helicopter's engines running creates a heightened level of noise, a downwash effect from the rotor blades, and potential safety concerns, making the process more complex than a cold load.

In contrast, a cold load occurs when the helicopter is stationary, with its engines off, allowing for a safer and more controlled environment for loading personnel and equipment. The engines being off reduces risks associated with the rotor wash and noise, ensuring that everyone involved can communicate more easily and perform their duties without the added challenge of an operating helicopter.

Understanding the distinction between hot and cold loads is essential for maintaining safety protocols and optimizing operational efficiency during air assault operations.
