1. A power control apparatus for an in-flight entertainment system, comprising:
- power supply means for providing power;
monitor means for detecting an on-board environmental condition, said monitor means receiving power independently of the environmental condition deteted by said monitor;
a power circuit for receiving power from the power supply and for coupling power to an electronic system; and
switch means coupled to the monitor means, said switch means for connecting the power supply means to the power circuit for providing power to the in-flight entertainment system upon detection of the environmental condition and otherwise completely disconnecting the power circuit from the power supply means without interrupting power to the monitor.

Abstract
The present invention is a method and apparatus for controlling power supply to aircraft electronic systems based on ambient environmental conditions. The apparatus comprises a monitor for detecting an environmental condition, a power supply for providing power, a circuit which receives power from the power supply, and a switch coupled to the monitor. Upon detection of the environmental condition, the switch connects the power supply to the circuit, otherwise the switch disconnects the circuit from the power supply.

19. A method of controlling power supply in an aircraft in-flight entertainment system, comprising:
-
detecting an on-board environmental condition; determining if the environmental condition is within a predetermined range independently of the detected environmental condition; and connecting a power supply to the aircraft in-flight entertainment system upon determination of the environmental condition being within said predetermined range, otherwise completely disconnecting the in-flight entertainment system from the power supply without interrupting said detecting. - View Dependent Claims (20, 21, 22)
