ENGINE INLET ANTI-ICING / DE-ICING SYSTEM

The system prevents ice from forming in the engine air inlet. The engine de-ice system is comprised of an engine hot air de-icing valve, located on the engine, pilot and gunner ENG DE-ICE switches and is protected by a 5 ampere ENG DE-ICE circuit breaker. The system is energized from the 28 Vdc essential bus. The valve may be controlled by either the gunner ENG DE-ICE switch, located on the gunner miscellaneous panel, or the pilot engine control panel. The de-ice system is normally energized to prevent the de-icing from activating. If either switch is placed to the DE-ICE position, the circuit is broken and the de-icing system is activated.
