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 (61)

1 . An aircraft refueling safety module, comprising:

a memory, and

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

compare data received from a first data source, the first data source data comprising at least a type of fuel required by an aircraft, to data received from a second data source not located at the aircraft, the second data source data comprising at least the type of fuel required by the aircraft; and

if the first data source data matches the second data source data, indicate that fuel should be dispensed to the aircraft, or

if the first data source data does not match the second data source data, indicate that fuel should not be dispensed to the aircraft.

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

compare at least one of the first data source data and the second data source data to data received from an enterprise, the enterprise data comprising the type of fuel required by the aircraft; and

if the enterprise data matches the at least one of the first data source data and the second data source data, indicate that fuel should be dispensed to the aircraft, or

if the enterprise data does not match the at least one of the first data source data and the second data source data, indicate that fuel should not be dispensed to the aircraft.

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

enable, if the enterprise data does not match the at least one of the first data source data and the second data source data, an operator alarm signal.

4 . The aircraft refueling safety module of claim 2 where the first data source 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.

5 . The aircraft refueling safety module of claim 4 where the one or more processors is further configured to:

compare the first data source 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 first data source 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 one first data source or the enterprise.

6 . The aircraft refueling safety module of claim 1 where the one or more processors is further configured to:

enable, if the first data source data does not match the second data source data, an operator alarm signal.

7 . The aircraft refueling safety module of claim 1 where the one or more processors is further configured to:

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

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

comparing, at one or more modules, data received from a first data source, the first data source data comprising a type of fuel required by an aircraft, to data received from a second data source not located at the aircraft, the second data source data comprising the type of fuel required by the aircraft; and

if the first data source data matches the second data source data, indicating that fuel should be dispensed to the aircraft, or

if the first data source data does not match the second data source data, indicating that fuel should not be dispensed to the aircraft.

9 . The aircraft refueling safety method of claim 8 further comprising:

comparing, at the one or more modules, at least one of the first data source data and the second data source data to data received from an enterprise, the enterprise data comprising the type of fuel required by the aircraft; and

if the enterprise data matches the at least one of the first data source data and the second data source data, indicating that fuel should be dispensed to the aircraft, or

if the enterprise data does not match the at least one of the first data source data and the second data source data, indicating that fuel should not be dispensed to the aircraft.

10 . The aircraft refueling safety method of claim 9 further comprising:

enabling, if the first data source data does not match the second data source data, an operator alarm signal.

11 . The aircraft refueling safety method of claim 9 further comprising:

enabling, if the enterprise data does not match the first data source data and the second data source data, an operator alarm signal.

12 . The aircraft refueling safety method of claim 9 where the first data source 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.

13 . The aircraft refueling safety method of claim 12 further comprising:

comparing, at the one or more modules, the first data source 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 one or more modules, based on the comparison, if the first data source 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 one first data source or the enterprise.

14 . The aircraft refueling safety method of claim 8 further comprising:

transmitting, from the one or more modules, the data indicating the type and amount of fuel dispensed to an enterprise.

15 . An aircraft servicing authorization system, comprising:

a verification module comprising:

a memory, and

one or more processors configured to:

receive first data from a first source relating to an aircraft;

receive second data from an enterprise relating to the aircraft;

compare the first data to the second data;

receive fuel requirement data; and

authorize fuel dispensing if:

the first data matches the second data.

16 . The aircraft servicing authorization system of claim 15 wherein the one or more processors are configured to:

determine if the first data or the second data requires updating based on the comparison; and

transmit updated data to at least one of the first source and the enterprise.

17 . The aircraft servicing authorization system of claim 15 wherein the one or more processors are configured to:

enable an alarm signal if the first data does not match the second data.

18 . The aircraft servicing authorization system of claim 15 wherein:

the first data comprises account data relating to an owner or operator of the aircraft.

19 . The aircraft servicing authorization system of claim 15 wherein:

the fuel requirement data is received from a second source not located at the aircraft.

20 . The aircraft servicing authorization system of claim 15 wherein the one or more processors are configured to:

transmit fuel dispensing data to the enterprise, the fuel dispensing data comprising a type and amount of fuel dispensed.
