Aircraft Fuel System Pressure Definitions
The information in this document is limited to aircraft engine fuel feed, refueling, and transfer components (see 2.1). It is assumed that isothermal, liquid fluid conditions exist, herein referred to as fuel. Where applicable and allowable, it is understood that a referee fluid may be substituted for fuel.
The word “pressure” can be combined with a dozen of different words to define a wide range of technical definitions; this AIR is intended to present a list of such definitions in order to assist the industry's work.
The SAE Five-Year Review process identified that the reference section needed updating and some pressure definitions could be improved. The revision also has been considered beneficial because the document was in the old format (typewriter created).
Sections 4 and 5 have been added to the document as the committee has considered important and were absent in the original document
