Abstract
An external power supply system for an aircraft includes a power receptacle configured to connect to an external power source to provide external power, a power switch operative to switch between a battery power source and the external power source, and a voltage check system configured to prevent at least one of under-voltage or over-voltage of an aircraft electrical system. The voltage check system includes a voltage relay sensor configured to determine if the external power is within a suitable voltage range and a check switch operatively connected to the voltage relay sensor, wherein if the external power is within a suitable voltage range, the voltage relay sensor activates the check switch to allow external power to the aircraft electrical system, and wherein if the external power is outside the suitable voltage range, then the voltage relay sensor does not allow power to the aircraft electrical system.
