Protecting aircrew, ground crew and aircraft from the wide variety of lethal nuclear, biological and chemicals agents in gaseous, liquid and particulate forms is difficult. At present it is most effective for aircrew in combat aircraft to wear individual protective equipment (IPE) which acts as an impregnable barrier within a cockpit that cannot itself be regarded as uncontaminated. After exploring the use of oversuits with integral transparent head covers, the UK adopted the aircrew respirator No5 (AR5) for comprehensive above-neck isolation. A combination of garments give comparable below-neck protection.
The AR5 is worn under the standard flying helmet. It has a rigid, polycarbonate faceplate at the front, bonded to an impervious rubber cowl that fits closely over the head and upper part of the neck. The cowl extends down over the shoulders to overlap the suit, with a compliant bellows section at collar level to allow the head to move without dragging the part draped over the shoulders.
This NBC Headgear from Gentex works in a similar fashion and was acquired to test fit under the Striker HMD
