Question: 1 / 1165

What defines a Light Sport Aircraft (LSA)?

Any aircraft weighing less than 1,200 pounds

An aircraft powered by a single reciprocating engine, not including rotorcraft or powered lift

A Light Sport Aircraft (LSA) is defined primarily by its compliance with specific regulatory standards set forth by the FAA. The correct answer indicates that it is an aircraft powered by a single reciprocating engine and explicitly excludes rotorcraft or powered lift. This definition is vital because LSAs must adhere to particular parameters, including weight, speed, and passenger capacity, which are outlined in 14 CFR 1.1 and 14 CFR 91.315.

While discussing the other options, it's worth noting that weight limitations, maximum speed, and certification are significant components of an LSA's characteristics. However, defining an LSA fundamentally involves recognizing it as an aircraft with a specific engine type, which narrows the scope and clarifies its classification within aviation regulations. The other choices, while related, don't encapsulate the core definition as effectively as the indication of the type of engine and the exclusions concerning other aircraft categories do.
