An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI),[1] which also ratifies any claims. Speed records are divided into a number of classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibians, and within these classes there are records for aircraft in a number of weight categories. There are still further subdivisions for piston-engined, turbojet, turboprop, and rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads.
