How much of the load is required to be within the load-bearing zone?

In aerial operations, particularly when considering the safe and efficient transport of loads by rotary-wing aircraft, the concept of a load-bearing zone is critical. The load-bearing zone is the area of the cargo that is effectively supported by the aircraft's structure and allows for optimal weight distribution during flight.

Requiring that at least 75% of the load be within this load-bearing zone ensures a number of factors are met. It promotes balance and stability, enables better handling characteristics for the aircraft, and minimizes the risk of shifting loads that could jeopardize safety during flight. Having a substantial portion of the load within this designated zone is crucial for fulfilling mission requirements while maintaining operational integrity.

Thus, the threshold of 75% is established to ensure that the majority of the load is distributed in a way that complies with safety regulations and enhances the aircraft's performance during transport missions.
