An airplane heating device. The device constitutes a light weight panel which generates heat uniformly over a broad area through the use of a heating foil composed of a flexible substrate coated or impregnated with a resistive material such as carbon particles in a resinous matrix. The foil is, in turn, embedded in a resinous-impregnated electrically nonconductive flexible substrate to form a sheet. The sheet is disposed on a light weight stiff panel of a material such as balsa or rigid foam to form a subassembly that is sandwiched between thin protective covers such as metal or plastic sheets. The heating panel can be used as a wall or floor heating plate in an airplane or as a component of a container-type airplane heating device such as a portable hotplate stove.
