12059 CONTAMINATION OF AIRCRAFT
a. Aircraft should only be on deck when necessary for operational reasons. Although external contamination
of aircraft is unlikely to affect their ability to fly, it will result in many contamination control
problems that will reduce the speed and efficiency of their operations. If the operational situation permits,
steps to avoid contamination should be taken. When chemical attack is imminent or has taken place, the
following actions should be taken as appropriate:
(1) Stow aircraft in hangars with doors shut and lift raised.
(2) Cover all openings and intakes on aircraft, paying particular attention to the internal atmosphere
of the aircraft.
(3) Launch aircraft to a helicopter haven or fixed-wing aircraft diversion airfield outside the likely
area of contamination (e.g., take aircraft under cover).
b. Commanding officers must thoroughly weigh recommended precautions and protective measures
under chemical threat against the required operational availability of own ship’s aircraft.
