1. Purpose: The pressurized refueling panel is designed for refueling tanks, transferring fuel from one tank to another, or refueling between tanks.
2. Location: The pressurized refueling panel is located on the refueling station.
3. Description (Composition): The refueling panel consists of three fuel gauges, three control switches for the refueling valves, three indicator lamps for valve modes, and a test switch for the indicator or an alternative switch for controlling the refueling power supply.
4. Connection: The refueling panel is connected by opening the refueling station door.
5. Power Supply: Refueling operations use 28 V AC and 115 V DC power. The electrical power is supplied by ground power, APU, or batteries.
6. Operation: When the refueling station door is opened, the refueling power supply switch is activated, and three white lamps illuminate on the panel (if power is not successfully activated, the panel power can be enabled by pressing the "auxiliary refueling power" switch).
