Water Filling System for Helicopters
Water Filling System for Helicopters : A system designed to allow a helicopter to fill its internal or external tanks with water while in flight. A water filling system will usually take the form of a fixed suction pump beneath the helicopter. To fill the water tank, the helicopter pilot flies stationary over a body of water with the pump submerged. Some systems operate a hydrofoil which allows for the tank to be filled up in mid-flight at low speed
