The term 'Flight Fig' is a reference to the F-16 Fighting Falcon, a single-engine supersonic multirole fighter aircraft developed by General Dynamics for the United States Air Force. The F-16 was the first of the modern fighters to enter service and has since become one of the most successful and widely used military aircraft in history. The acronym ALT stands for 'ALTITUDE, ' which is the height above sea level at which an aircraft is flying. ALTITUDE is an important factor in the performance of an aircraft, as it affects the amount of lift generated by its wings.
