How should the tear-away pull knobs of the AERP be positioned during wear?

During wear, the tear-away pull knobs of the AERP (Advanced Emergency Restraint Parachute) should be positioned under the lower harness straps. This positioning is essential for ensuring that the pull knobs are easily accessible to the aircrew member during emergency situations. By placing them under the lower harness straps, they remain secure and out of the way during regular operations, but can be quickly and effectively accessed in the event of an emergency where rapid detachment from the parachute system is required.

The correct positioning helps in preventing accidental deployment and ensures that the aircrew member can respond swiftly without fumbling to locate the knobs. This design consideration reflects a careful analysis of safety and usability, providing maximum protection while maintaining operational efficiency.
