Disclosed are systems and methods for testing aircraft engine that are not currently associated with a functional aircraft or systems. For testing, systems on the engine being tested are connected with the reciprocating systems (e.g., engine electronic controls, main and motive fuel) on a fully functional aircraft using conduits that have been extended to lengths enabling the connection.

A multiply-redundant system that protects fueling of rockets, aircraft and other vehicles using Liquefied Natural Gas (LNG) along with an oxidizer such as Liquefied Oxygen. One or more sensors in combination with one or more optional microswitches combine to detect any leaks, fire or explosion hazards quickly locking out further fueling. For different levels of safety, different combinations of sensors can be used.

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.

A refuelling system suitable for use with an overwing fuelled aircraft comprising: (b) a stored fuel grade identification means for identifying the fuel grade stored in the fuel storage vessel and available type(s) of delivery of the fuel to the aircraft; (d) an aircraft fuel grade identification means being attached to, or forming part of, an overwing fuelled aircraft, wherein said aircraft fuel grade identification means represents the fuel grade requirement of the aircraft and is readable from the exterior of the aircraft; (g) a transmission and receiving system which enables information regarding the fuel grade that had previously been supplied to the aircraft having the aircraft registration number inputted into the computer interface and the type of delivery of fuel which may be used by said aircraft to be retrieved from a remote database; (i) an automated cross-check system which is configured to retrieve the fuel grades identified by the fuel identification means in (b), retrieve the fuel grade identified in (d) from the hand-held device, retrieve the type(s) of delivery of fuel identified by the fuel identification means in (b) and by the system of element (g), and the previous fuel grade supplied to the aircraft identified by the system in element (g) which can generate a positive response signal if all of the fuel grades identified are compatible with each other and the type(s) of delivery of fuel to the aircraft are compatible.
