Appl. No.:

Abstract:
The present invention is an aircraft engine heating system and the associated method of its operation. The system contains an electric heater comprised of an electrical heating element, thermostat and fan. A power cord is provided for supplying electricity to the heating element and the fan. Two metal tubing adaptors attach to the front and rear of the heater. A flexible, heat-resistant tube is connected to each adaptor via metal fasteners. The front tube is inserted in to the engine intake vent of an aircraft. This tube directs warm air into the aircraft engine. The return tube leads from the other aircraft engine vent to the rear of the heat system. In this way, warm air is re-circulated through the aircraft engine, warming the engine more quickly and reducing the power demands to operate the system.
