An Airplane, Single Engine, Land certificate (ASEL) is part of the Federal Aviation Administration (FAA) testing and certification standard: within a privilege level, it is a class rating as part of pilot certification in the United States. An ASEL identifies that the pilot in question holds a pilot licensefor a fixed-wing aircraft that has a single engine and only lands on land—not a seaplane.[1] ASEL is the most common license sought by private pilots;[2] to specify that it is a Private Pilot License, it can be referred to as P/ASEL or PP-ASEL.
