Abstract: Deicer sprayer for deicing aircraft includes a deicer fluid container with an enclosed thermostatically controlled electrical heater designed for connection to an external power source to heat deicer fluid prior to its application to an aircraft wing. A flexible line having a hand operated valve, a wand and an adjustable spray nozzle connected to the container allow directed delivery of the deicing fluid. The deicer fluid container can be enclosed within a thermal insulation blanket which helps to maintain the deicer fluid temperature during system use. Attached to the deicer fluid container is a carrying strap and harness which permits the individual user to move about easily during the operation of the portable deicer sprayer system while deicing aircraft.
