Naval Air Warfare Center evaluated the physiological and subjective responses of 28 aircrew wearing the AP22P-9V USMC Helicopter Aircrewman Chemical, Biological CB Protection Ensemble during warmhot weather ground and flight testing in four USMC helicopter types. Ground testing evaluated fit, donning and doffing, flight equipment compatibility, mobility, dexterity, ingress, egress, emergency egress, water survivability, crewstation compatibility, and repeated preflight inspections in CH-53, CH-46, UH-1N, and AH-1 helicopters. CH-53 and UH-1N flight testing compared three clothing configurations the AP22P-9V, AP22P-9V above-the-neck respirator assembly only, and standard flight clothing and two test conditions 4-hr flight profile without DT and preflight inspections. During three summers of AP22P-9V testing 1988-1990, aircrew completed 44 test trials and 142 hr wear time. Ambient temperatures ranged from 22 deg 72 deg F in the ready room to 40 deg C 104 deg F in flight. Author
