How much must the edges overlap when repairing tears on the CWU 66P aircrew chemical ensemble?

When repairing tears on the CWU 66P aircrew chemical ensemble, the edges must overlap by 1/4 inch. This overlap is critical as it ensures that the integrity of the material is maintained and that the repair effectively restores the ensemble's protective functions. A 1/4 inch overlap provides a balance between sufficient coverage for sealing the tear while not compromising the garment’s flexibility and overall fit. This specific measurement is based on industry standards for repairing flight gear and ensures optimal performance and safety for aircrew members. Proper overlap helps to prevent future tearing and ensures that any chemicals or hazards that the ensemble is designed to protect against are effectively contained.
