How should the manifold assembly be positioned on the aircrew member’s body?

The correct positioning of the manifold assembly on the aircrew member's body is crucial for both safety and functionality. When positioned in the same location as the torso harness dovetail fitting, the manifold assembly is optimally placed to ensure that all aircrew flight equipment remains securely attached and properly operates during flight. This location helps to maintain the integrity of the harness system, allowing for smooth and effective interactions with other equipment, such as the ejection seat or escape systems.

This positioning also facilitates easy access to the manifold controls while ensuring that they do not interfere with the aircrew member’s mobility or the safe operation of the aircraft. It is critical for the manifold to be aligned with the torso harness because it ensures that forces are distributed appropriately during maneuvers, preventing potential injury or equipment failure.

Other positions, such as placing the manifold assembly above the shoulder line, on the lower back, or at arm's length, could hinder accessibility or potentially create safety hazards during flight operations, indicating that maintaining the standard position is essential for optimal performance and safety.
