Discuss icing and its effects on the performance of naval aircraft.
Ice on the airframe decreases lift and increases drag, weight, and stalling speed. The accumulation of ice in exterior movable surfaces affects the control of the aircraft. If ice begins to form on the blades of a propeller, the propeller's efficiency is decreased or further power is demanded of the engine to maintain flight. Most aircraft have sufficient reserve power to fly with a heavy load of ice, but airframe icing is a serious problem because it results in increased fuel consumption and decreased range. The possibility always exists that engine system icing may result in loss of power. Icing can cause: loss of engine power, aerodynamic efficiency, loss of proper operation of control surfaces, brakes and landing gear, loss of outside vision, false instrument indications, and loss of radio.
