What is the primary purpose of the aircrew eye respiratory protection (AERP) system?

The primary purpose of the aircrew eye respiratory protection (AERP) system is to protect against chemical agents. This system is designed to ensure that aircrew members can operate safely in environments where there may be exposure to hazardous chemicals, such as toxic fumes, gases, or biological agents. By providing this level of protection, the AERP system plays a crucial role in safeguarding the health and safety of aircrew during operations where such risks are present.

In addition to this main function, the AERP system incorporates features to address other concerns, but its primary focus is on chemical protection, ensuring aircrew members can perform their duties effectively while minimizing health risks posed by airborne contaminants.
