Abstract
A forward in flight entertainment system (IFE) which allows air to be directed to and exhausted from the IFE equipment in isolation from the cabin conditioned air. Further, potential IFE generated smoke may be kept isolated from the cabin air. The forward IFE equipment is located in forward sections of the aircraft system switching from ground to air mode is accomplished through air/ground signal 10 responsive to landing gear truck tilt. Once the air/ground transition from ground mode to air mode has occurred, ventilation valves 1 and 2 will be closed and the heated air will be exhausted overboard by forward IFE cooling overboard valve 4 whose overboard flow increases with altitude and cabin to ambient pressure differential.
