The information to be exchanged concerns an amount of water for the vehicle. The amount of water on board of the vehicle is automatically measured by a device for determining the amount of water. The transmitter of a device for exchanging information at the vehicle automatically and wirelessly transmits the information concerning the current amount of water to a receiver of a device for exchanging information at an information center. New information parameters are wirelessly transmitted from the transmitter of the device for exchanging information at the information center to the receiver of the device for exchanging information at the vehicle. ## Claims ### Claim 1 A method for exchanging information between a vehicle and an information center, the information concerning an amount of water for the vehicle, the method comprising: determining the amount of water; and automatically exchanging information about the determined amount of water via wireless communication; wherein the automatic exchange of information comprises submitting information indicating new parameters concerning an amount of water from the information center to the vehicle. ### Claim 2 (depends on 1) The method of claim 1, wherein the automatic exchange of information further comprises: requesting a status report by the information center from the vehicle, the status report indicating current parameters concerning the determined amount of water; sending the status report by the vehicle to the information center. ### Claim 3 (depends on 2) The method of claim 2, wherein the new parameters are determined based on the information only available at the information center. ### Claim 4 (depends on 1) The method of claim 1, wherein the automatic exchange of information further comprises: acknowledging received information by sending a validation signal from the vehicle to the information center. ### Claim 5 (depends on 1) The method of claim 1, wherein the automatic exchange of information further comprises: activating of received information by a separate command submitted by the information center to the vehicle. ### Claim 6 (depends on 1) The method of claim 1, wherein the automatic exchange of information further comprises: sending a final confirmation from the vehicle to the information center. ### Claim 7 (depends on 1) The method of claim 1, further comprising providing the exchanged information to a data output device located at the vehicle. ### Claim 8 (depends on 1) The method of claim 1, wherein the information is exchanged using at least one of HF signal transmission, VHF signal transmission and satellite signal communication. ### Claim 9 A system for exchanging information between a vehicle and an information center, the information concerning an amount of water for the vehicle, the system comprising: a device for determining the amount of water; a device for automatically exchanging information about the determined amount of water via wireless communication; and a receiver adapted for receiving submitted information from the information center, wherein the information is indicating new parameters concerning an amount of water. ### Claim 10 (depends on 9) The system of claim 9, wherein the device for automatically exchanging information further comprises: a transmitter adapted for sending the status report to the information center; wherein the receiver is further adapted for receiving a request for a status report from the information center, the status report indicating current parameters concerning the determined amount of water. ### Claim 11 (depends on 9) The system of claim 9, wherein the device for automatically exchanging information comprises a transmitter adapted for acknowledging the received information by sending back a valid value to the information center. ### Claim 12 (depends on 9) The system of claim 9, wherein the device for automatically exchanging information comprises a receiver is adapted for activating received information by receiving a separate command submitted by the information center. ### Claim 13 (depends on 9) The system of claim 9, wherein the device for automatically exchanging information comprises a transmitter adapted for sending a final confirmation to the information center. ### Claim 14 (depends on 9) The system of claim 9, further comprising a data output device located at the vehicle. ### Claim 15 An aircraft comprising a system for exchanging information between a vehicle and an information center, the information concerning an amount of water for the vehicle, the system comprising: a device for determining the amount of water; a device for automatically exchanging information about the determined amount of water via wireless communication; and a receiver adapted for receiving submitted information from the information center, wherein the information is indicating new parameters concerning an amount of water. ### Claim 16 A system for exchanging information concerning an amount of water for a vehicle between the vehicle and an information center, comprising a processor programmed with a set of instructions for: determining the amount of water; and automatically exchanging information about the determined amount of water via wireless communication; wherein the automatic exchange of information comprises submitting information indicating new parameters concerning an amount of water from the information center to the vehicle. ### Claim 17 In a system for exchanging information between a vehicle and an information center, concerning an amount of water for the vehicle, a computer readable medium storing instructions for causing a processor to: determine the amount of water; and automatically exchange information about the determined amount of water via wireless communication; wherein the automatic exchange of information comprises submitting information indicating new parameters concerning an amount of water from the information center to the vehicle. ### Claim 18 An aircraft comprising a system for exchanging information between a vehicle and an information center, the information concerning an amount of water for the vehicle, the system comprising: means for determining the amount of water; means for automatically exchanging information about the determined amount of water via wireless communication; and a receiver adapted for receiving submitted information from the information center, wherein the information is indicating new parameters concerning an amount of water.
