A fuel transfer apparatus for an aircraft comprises: two or more fuel tanks (2,3,4,5,6) arranged in an inboard to outboard alignment, at least one being situated in the wing (1) of the aircraft, means for transferring fuel between the tanks (8, 9) , and a fuel management system (10) for controlli
A fuel transfer apparatus for an aircraft comprises: two or more fuel tanks (2,3,4,5,6) arranged in an inboard to outboard alignment, at least one being situated in the wing (1) of the aircraft, means for transferring fuel between the tanks (8, 9) , and a fuel management system (10) for controlling and monitoring the transfer of fuel between tanks the fuel management system comprises; means for receiving a first input signal that the aircraft has left the ground, means for receiving a second input signal that the aircraft is approaching its destination, means for initiating the transfer of the fuel from a relatively inboard tank location to a relatively outboard tank location in response to the first input signal, and means for initiating the transfer of the fuel from a relatively outboard tank location to a relatively inboard tank location in response to the second input signal.

The invention claimed is: 1. A fuel transfer apparatus for an aircraft comprising: at least two fuel tanks arranged in an inboard to outboard alignment, at least one tank being situated in a wing of the aircraft, at least one pump for transferring fuel between the tanks, and a fuel management system for controlling and monitoring the transfer of fuel between tanks, said system comprising: means for receiving a first input signal that the aircraft has left the ground; means for receiving a second input signal that the aircraft is approaching its destination, means for initiating the transfer of the fuel from a relatively inboard tank location to a relatively outboard tank location in response to the first input signal, and means for initiating the transfer of the fuel from a relatively outboard tank location to a relatively inboard tank location in response to the second input signal, wherein the fuel management system is computerised and comprises a computer algorithm designed to respond to the various input signals and initiate the fuel transfer in the desired sequence, wherein the computer algorithm is specific to a pre-programmed flight path for the aircraft. 2. A fuel transfer apparatus for an aircraft comprising: at least two fuel tanks arranged in an inboard to outboard alignment, at least one tank being situated in a wing of the aircraft, at least one pump for transferring fuel between the tanks, and a fuel management system for controlling and monitoring the transfer of fuel between tanks, said system comprising: means for receiving a first input signal that the aircraft has left the ground; means for receiving a second input signal that the aircraft is approaching its destination, means for initiating the transfer of the fuel from a relatively inboard tank location to a relatively outboard tank location in response to the first input signal, and means for initiating the transfer of the fuel from a relatively outboard tank location to a relatively inboard tank location in response to the second input signal, wherein the fuel management system is programmed to respond to a second input signal that the aircraft has descended to a certain altitude on its approach to land. 3. A fuel transfer apparatus for an aircraft comprising: at least two fuel tanks arranged in an inboard to outboard alignment, at least one tank being situated in a wing of the aircraft, at least one pump for transferring fuel between the tanks, and a fuel management system for controlling and monitoring the transfer of fuel between tanks said system comprising: means for receiving a first input signal that the aircraft has left the ground; means for receiving a second input signal that the aircraft is approaching its destination, means for initiating the transfer of the fuel from a relatively inboard tank location to a relatively outboard tank location in response to the first input signal, and means for initiating the transfer of the fuel from a relatively outboard tank location to a relatively inboard tank location in response to the second input signal, wherein said second input signal is relayed between the flight control program and the fuel management system when a certain point on a pre-programmed flight path has been reached. 4. A fuel transfer apparatus for an aircraft comprising: at least two fuel tanks arranged in an inboard to outboard alignment, at least one tank being situated in a wing of the aircraft, at least one pump for transferring fuel between the tanks, and a fuel management system for controlling and monitoring the transfer of fuel between tanks, said system comprising: means for receiving a first input signal that the aircraft has left the ground; means for receiving a second input signal that the aircraft is approaching its destination, means for initiating the transfer of the fuel from a relatively inboard tank location to a relatively outboard tank location in response to the first input signal, and means for initiating the transfer of the fuel from a relatively outboard tank location to a relatively inboard tank location in response to the second input signal, wherein the fuel management system will have manual override facility to enable flight crew to adapt to unforeseen circumstances.
