Abstract
A system comprised of switches, fuses, microprocessor-based monitoring, and a pilot display that provides a method to bypass computer-controlled switching of aircraft power circuits. A backup circuit in addition to the computer-controlled switching circuit provides a method to guarantee power delivery in the case of a failure of the computer-controlled switch. The system provides the pilot with an indication when the backup circuit is engaged. When the other devices are turned off and/or the engine is shut down, an indication can be provided to the pilot that the backup circuit is on. An indication can also be provided to the pilot that the switch is in the off position when it should be on.
