Heating and Ventilating of Cabin Airplanes

Comfort for airplane passengers is being seriously considered, and aeronautical engineers are designing features for the airplane cabin that follow closely the comforts of railroad drawing-room cars and the facilities of the larger motor coaches. The adaptation is easily made, with alterations in weight and size. Heating and ventilating systems are replacing the rudimentary provisions of the past. The paper states the problems of heating and ventilating of cabin airplanes, gives available data, describes methods in use or attempted, and urges the mechanical and aeronautical branches of the profession to join in solving the problems.
