==Definitions==
Many definitions of STOL have been used over time and for regulatory and military purposes.<ref name="Columbia" /> These include:

|quote=heavier-than-air craft, capable of rising from and descending to the ground with only a short length of runway, but incapable of doing so vertically. The precise definition of an STOL aircraft has not been universally agreed upon. However, it has been tentatively defined as an aircraft that upon taking off needs only 1,000 ft (305 m) of runway to clear a 50-ft (15-m) obstacle at the end of that distance and upon landing can clear the same obstacle and then land within 1,000 ft.

|quote=The STOL mode of flight is one during which an airplane taking off or landing is operated at climb-out and approach speeds lower than the conventionally accepted margins of airspeed above the power-off stalling speed of the airplane.

Some manufacturers market their products as STOL without specifying that the aircraft meets an accepted functional definition.<ref name="FisherHorizon1">{{cite web|url = http://www.fisherflying.com/index.php?option=com_content&view=article&id=40&Itemid=22|title = Horizon 1 |access-date = 2009-10-27|last = Fisher Flying Products}}</ref>
