Definition
A category of small, simple aircraft defined by the FAA with strict limits on weight, speed, seating, and configuration. A light-sport aircraft (LSA) has a maximum gross takeoff weight of 1,320 pounds (1,430 pounds for seaplanes), a maximum of two seats, a single reciprocating engine, fixed landing gear (or repositionable for seaplanes), a fixed-pitch or ground-adjustable propeller, an unpressurized cabin, and a maximum level-flight speed of 120 knots. LSAs may be flown by pilots holding a Sport Pilot certificate or higher.
Plain English
A small, basic aircraft that meets a specific FAA size and performance limit, designed to be flown by pilots with the simplest type of pilot certificate.
Context Anchor
Seen when discussing sport pilot flying, light-sport training, and aircraft types used for simpler recreational or entry-level flight operations.
Derivation
Light' refers to the weight limit, and 'sport' reflects the category's intent: recreational flying rather than commercial or heavy operations. The term was created by the FAA in 2004 when the Sport Pilot rule established this new aircraft category.
Why Pilots Care
It enables more accessible and affordable flying for recreational pilots.
Intuition Check
Do not read “sport” as meaning unsafe, casual, or toy-like. Here it points to a specific FAA-defined class of simpler, lighter aircraft with set limits.
Example Sentence 1
She earned her Sport Pilot certificate so she could fly a light-sport aircraft on weekends without needing a full medical certificate.
Example Sentence 2
Many flight schools use light-sport aircraft for introductory flights because they are simpler to operate.
