Why should starch not be used on the aircrew combat uniform?

Starch should not be used on the aircrew combat uniform primarily because it reduces the flame resistance capabilities of the fabric. The materials used in aircrew uniforms are specifically designed to provide a level of protection in high-temperature scenarios, such as from fire or explosions. Starch can alter the chemical properties of the fabric, potentially compromising its ability to resist flames and heat. This could put aircrew members at increased risk during flight operations, especially in combat situations where exposure to fire is a possibility.

This understanding emphasizes the importance of maintaining the specialized properties of protective uniforms, which are crucial for the safety and effectiveness of aircrew. Other options, although they may contain elements of truth, do not directly address the specific risks associated with flame resistance that make starching the uniform inadvisable. Therefore, the primary consideration remains the impact on the uniform's flame-resistant qualities.
