A water scavenging system (1) for removing water from an aircraft fuel tank (2), the water scavenging system comprising: a water line (10); and a valve (20) which is configured to control the flow of water in the water line in response to a change in an effective angle of the valve. In use, the valve opens automatically in response to an increase in the effective pitch of the aircraft during take off and climb. The valve comprises: a pendulum (40); and a valve closure member (46) which is coupled to the pendulum such that a change in the angular position of the pendulum relative to the water line causes the valve closure member to move from a closed position in which the valve closure member impedes the flow of water in the water line to an open position in which water can flow through the valve.

1. An aircraft having an engine, a fuel tank and a water scavenging system configured to remove water from the fuel tank and feed said water into said engine, the water scavenging system comprising: a water line; anda valve which is configured to allow the flow of water in the water line in response to an increase of an effective pitch of the aircraft to a predetermined effective pitch. 2. The aircraft of claim 1 wherein the valve comprises: a pendulum; anda valve closure member is coupled to the pendulum such that a change in the angular position of the pendulum to a predetermined angular position causes the valve closure member to move from a closed position in which the valve closure member impedes the flow of water in the water line to an open position in which water can flow through the valve. 3. The aircraft of claim 2 wherein the valve closure member translates between open and closed positions. 4. The aircraft of claim 1 wherein the valve has a closed configuration in which it substantially prevents the flow of water in the water line. 5. The aircraft of claim 1, wherein said predetermined effective pitch of the aircraft is 7 degrees. 6. A water scavenging system for removing water from an aircraft fuel tank, the water scavenging system comprising: a water line; anda valve which is configured to control the flow of water in the water line in response to a change in an effective angle of the valve, wherein the valve comprises: a pendulum; anda valve closure member which is coupled to the pendulum such that a change in the angular position of the pendulum relative to the water line causes the valve closure member to move from a closed position in which the valve closure member impedes the flow of water in the water line to an open position in which water can flow through the valve, wherein the pendulum is coupled to a cam; and wherein the valve closure member comprises a cam follower and a biasing member for biasing the cam follower into engagement with the cam. 7. The system of claim 6 wherein the biasing member comprises a coil spring. 8. A water scavenging system for removing water from an aircraft fuel tank, the water scavenging system comprising: a water line; anda valve which is configured to control the flow of water in the water line in response to a change in an effective angle of the valve, wherein the valve comprises: a pendulum; anda valve closure member which is coupled to the pendulum such that a change in the angular position of the pendulum relative to the water line causes the valve closure member to move from a closed position in which the valve closure member impedes the flow of water in the water line to an open position in which water can flow through the valve, wherein the valve closure member is coupled to the pendulum by a link which is rotatably coupled to the valve closure member at one end and rotatably coupled to the pendulum at another end. 9. A water scavenging system for removing water from an aircraft fuel tank, the water scavenging system comprising: a water line; anda valve which is configured to control the flow of water in the water line in response to a change in an effective angle of the valve, wherein the valve comprises: a pendulum; anda valve closure member which is coupled to the pendulum such that a change in the angular position of the pendulum relative to the water line causes the valve closure member to move from a closed position in which the valve closure member impedes the flow of water in the water line to an open position in which water can flow through the valve, wherein the valve closure member rotates between its open and closed positions. 10. A method of removing water from an aircraft fuel tank, said aircraft fuel tank mounted in an aircraft, the method comprising: opening a valve in response to an increase in an effective pitch of the aircraft to a predetermined effective pitch of the aircraft to enable water to flow in a water line; andfeeding water from the water line into an engine of the aircraft. 11. The method of claim 10 further comprising closing the valve in response to a decrease in the effective pitch of the aircraft to less than said predetermined effective pitch. 12. The method of claim 10, where in the predetermined effective pitch of the aircraft is 7 degrees.
