A STOLport or STOLPORT was an airport designed with STOL (Short Take-Off and Landing) operations in mind, usually for an aircraft class of certain weight and size. The term "STOLport" did not appear to be in common usage as of 2008, although was commonly used by pilots flying into Biggin Hill during 1986/87 when the London City Airport was opened restricting approaches and ceilings to the north of Biggin. A STOLport normally had a short single runway, in general shorter than 1,500 m (5,000 ft). STOLports only accepted certain types of aircraft, often only smaller propeller aircraft, and often with limits on the amount of fuel that can be taken. In the United States, short runway facilities are simply known as airports, and the term "STOLport" has not been commonly used since the early 1970
