Abstract

A system ensures the correct type of fuel is dispensed in an aircraft while removing the introduction of human error in the refueling process. The system includes an RFID tag disposed at one or more aircraft that electronically stores data such as engine type, engine hours, fuel type, tail number, and pilot/subscriber data for the aircraft on which the RFID tag is disposed. An RFID reader is disposed at or near a fuel dispensing mechanism, such as a fuel truck or tank. A signal indicative of fuel type is emitted from the RFID tag to the RFID reader. RFID tags on aircraft that are enrolled in the system'"'"'s subscription service enable aircraft to be recognized by a module operating the fuel dispensing mechanism. Based on a comparison performed by the module, authorization to begin fueling is either permitted or declined.

Claims

1. An aircraft refueling safety module, the module comprising:

a memory, and

one or more processors in communication with the memory, the one or more processors configured to;

compare data in a data structure wirelessly received from an RFID tag located at an aircraft, the RFID tag data comprising data identifying the aircraft and the type of fuel required by the aircraft to data manually entered by an operator, the operator-entered data comprising data identifying the aircraft and the type of fuel required by the aircraft;

determine, based on the comparison, if the RFID tag data matches the operator-entered data; and

if the RFID tag data matches the operator-entered data, transmit an enable signal to allow fuel to be dispensed to the aircraft, or

if the RFID tag data does not match the operator-entered data, transmit a disable signal to prevent fuel from being dispensed to the aircraft.

2. The module of claim 1 where the one or more processors is further configured to:

compare the RFID tag data and the operator-entered data to data in a data structure received from an enterprise, the enterprise data comprising data identifying the aircraft and the type of fuel required by the aircraft;

determine, based on the comparison, if the enterprise data matches the RFID tag data and the operator-entered data; and

if the enterprise data matches the RFID tag data and the operator-entered data, transmit an enable signal to allow fuel to be dispensed to the aircraft, or

if the enterprise data does not match the RFID tag data and the operator-entered data, transmit a disable signal to prevent fuel from being dispensed to the aircraft.

3. The module of claim 2 where the one or more processors is further configured to:

enable, if the enterprise data does not match the RFID tag data and the operator-entered data, an operator alarm signal.

4. The module of claim 1 where the one or more processors is further configured to:

enable, if the RFID tag data does not match the operator-entered data, an operator alarm signal.

5. The module of claim 1 where the one or more processors is further configured to:

store, in a computer memory, a data structure comprising data indicating the type and amount of fuel dispensed to the aircraft; and

transmit the data indicating the type and amount of fuel dispensed to an enterprise.

6. The module of claim 1 wherein the RFID tag data further comprises account data relating to an owner or operator of the aircraft and the enterprise data further comprises account data relating to the owner or operator of the aircraft.

7. The module of claim 6 where the one or more processors is further configured to:

compare the RFID tag data relating to the owner or operator of the aircraft to the enterprise data relating to the owner or operator of the aircraft;

determine, based on the comparison, if the RFID tag data relating to the owner or operator of the aircraft or the enterprise data relating to the owner or operator of the aircraft must be updated; and

if an update is required, transmit the updated data to at least the RFID tag or the enterprise.

8. An aircraft refueling safety method, the method comprising:

comparing, at a module, data in a data structure wirelessly received from an RFID tag located at an aircraft, the RFID tag data comprising data identifying the aircraft and the type of fuel required by the aircraft to data manually entered by an operator, the operator-entered data comprising data identifying the aircraft and the type of fuel required by the aircraft;

determining, at the module, based on the comparison, if the RFID tag data matches the operator-entered data; and

if the RFID tag data matches the operator-entered data, transmitting an enable signal to allow fuel to be dispensed to the aircraft, or

if the RFID tag data does not match the operator-entered data, transmitting a disable signal to prevent fuel from being dispensed to the aircraft.

9. The method of claim 8 further comprising:

comparing, at the module, the RFID tag data and the operator-entered data to data in a data structure received from an enterprise, the enterprise data comprising data identifying the aircraft and the type of fuel required by the aircraft;

determining, at the module, based on the comparison, if the enterprise data matches the RFID tag data and the operator-entered data; and

if the enterprise data matches the RFID tag data and the operator-entered data, transmitting an enable signal to allow fuel to be dispensed to the aircraft, or

if the enterprise data does not match the RFID tag data and the operator-entered data, transmitting a disable signal to prevent fuel from being dispensed to the aircraft.

10. The method of claim 8 further comprising:

enabling, if the RFID tag data does not match the operator-entered data, an operator alarm signal.

11. The method of claim 9 further comprising:

enabling, if the enterprise data does not match the RFID tag data and the operator-entered data, an operator alarm signal.

12. The method of claim 8 further comprising:

storing, at the module, a data structure comprising data indicating the type and amount of fuel dispensed to the aircraft;

transmitting, from the module, the data indicating the type and amount of fuel dispensed to an enterprise.

13. The method of claim 8 wherein the RFID tag data further comprises account data relating to an owner or operator of the aircraft and the enterprise data further comprises account data relating to the owner or operator of the aircraft.

14. The method of claim 13 further comprising:

comparing, at the module, the RFID tag data relating to the owner or operator of the aircraft to the enterprise data relating to the owner or operator of the aircraft;

determining, at the module, based on the comparison, if the RFID tag data relating to the owner or operator of the aircraft or the enterprise data relating to the owner or operator of the aircraft must be updated; and

if an update is required, transmitting the updated data to at least the RFID tag or the enterprise.
