Abstract
A system for filling a tank for a firefighting helicopter with water without ground personnel, comprising a pilot controlled valve assembly to selectively permit water to flow into the refill tank upon the receipt of a communication transmitted by a communication device within the helicopter. The pilot controlled valve assembly can include a supply valve configured to move between at least a closed state and an open state, a controller configured to control the supply valve, and a receiver configured to send a signal to a controller to cause the controller to at least open the supply valve upon receipt by the receiver of a communication meeting one or more predetermined criteria. The water tank can be filled from a water source, including a municipal water source, when the supply valve is open to provide a more efficient, semi-autonomous refill tank system greatly improves costly and time-consuming manually refill systems.
