What is the best ramp angle for a CH-47?

The best ramp angle for a CH-47 is 3 degrees below horizontal. This angle is optimal for various operational reasons. It facilitates the loading and unloading of troops and equipment, ensuring that ramp access is safe and efficient. A slight downward angle allows gravity to assist in the movement of personnel or gear onto the aircraft while maintaining stability and control.

Additionally, a ramp angle of 3 degrees below horizontal helps in aligning with ground surfaces, making it easier for aircrew and passengers to enter and exit the aircraft without difficulty. If the ramp were at a steeper angle, it could increase the risk of accidents during loading operations and complicate the process, especially in adverse conditions. Therefore, this specific angle is chosen to enhance operational effectiveness while prioritizing safety.
