Definition of a Light Sport Aircraft (LSA)
In the United States, the FAA has defined the LSA airworthiness requirements to mean an aircraft, other than a helicopter or powered-lift that, since its original certification, has continued to meet the following:
- A maximum takeoff weight of not more than 1,320 pounds for aircraft not intended for operation on water; or 1,430 pounds for an aircraft intended for operation on water.
- A maximum airspeed in level flight with maximum continuous power (VH ) of not more than 120 knots CAS under standard atmospheric conditions at sea level.
- A maximum never-exceed speed (VNE ) of not more than 120 knots CAS for a glider.
- A maximum stalling speed or minimum steady flight speed without the use of lift-enhancing devices of not more than 45 knots CAS at the aircraft’s maximum certificated takeoff weight and most critical center of gravity.
- A maximum seating capacity of two persons, including the pilot.
- A single, reciprocating engine, if powered.
- A fixed-pitch propeller or ground-adjustable propeller, except for powered gliders which can have a feathering propeller system.
- A nonpressurized cabin, if equipped with a cabin.
- Fixed landing gear, except for an aircraft intended for operation on water or a glider.
- Fixed or retractable landing gear, or a hull, for an aircraft intended for operation on water.
- Fixed or retractable landing gear for a glider.
