Physiological and Subjective Responses to Wearing the A/P22P-9(V) Helicopter Aircrewman Chemical, Biological Protection Ensemble [open pdf - 4MB]
"Naval Air Warfare Center evaluated the physiological and subjective responses of 28 aircrew wearing the A/P22P-9(V) USMC Helicopter Aircrewman Chemical, Biological (CB) Protection Ensemble during warm/hot 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 A/P22P-9(V), A/P22P-9(V) above-the-neck respirator assembly only, and standard flight clothing) and two test conditions (4-hr flight profile without D/T and preflight inspections). During three summers of A/P22P-9(V) 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."
