A valve assembly () for an aircraft water supply system. The valve assembly () comprises a valve member (), an electrical motor (), and a mechanical returning mechanism (). When electrical power is provided, the motor () can be controlled to move the valve member () from a first position and to a second position. The mechanism () is operably connected to the valve member () and mechanically biases it towards the first position. If a power loss occurs when the valve member () is in the second position, the returning mechanism () non-electrically (e.g., mechanically) returns the valve member () to the first position.

A method of removing a delay-induced ice accumulation (e.g., an ice cap) from an airfoil's leading-edge region with a zoned electrothermal device. The method comprises delay-rectifying steps which are performed prior to routine-deicing steps. The delay-rectifying steps comprise continuously heating the parting strip (PS), continuously heating the upper fore zone (UF), and continuously heating the lower fore zone (LF). These steps efficiently and effectively remove the delay-induced ice accumulation, whereby routine deicing can be resumed.
