By what part of an inch must the edge overlap when repairing tears on the CWU-66/P aircrew chemical ensemble?

When repairing tears on the CWU-66/P aircrew chemical ensemble, the edge must overlap by 1/4 inch. This specific measurement is crucial to ensure the integrity and functionality of the repair. An overlap of this magnitude provides sufficient surface area for adhesive bonding or sewing, which helps maintain the ensemble's protective qualities against chemical agents.

A 1/4 inch overlap is considered optimal because it offers a balance between strength and flexibility, ensuring that the repair can withstand the rigors of flight and the operational environment while still allowing for some movement. This detail is particularly important given the potential exposure to hazardous substances, where even minor compromises in the ensemble's structure could lead to significant safety risks for the aircrew.
