In aviation, a class rating is an allowance to fly a certain group of aircraft that require training common to all aircraft within the group. A type rating is specified if a particular aircraft requires additional specialized training beyond the scope of initial license and aircraft class training. Which aircraft require a type rating is decided by the local aviation authority. Almost all single-engine piston (SEP) or multi-engine piston (MEP) single pilot aircraft can be flown without a type rating, but are covered by a class rating instead.
United States
In the United States, all turbojets require a type rating. Aircraft with a maximum take-off weight of more than typically require a type rating.
In the United States, there are seven categories of aircraft, which contain the following classes: CategoryClass CategoryClassAirplaneSingle-engine land (ASEL)Lighter-than-airAirshipMultiengine land (AMEL)BalloonSingle-engine sea (ASES)Powered-liftMultiengine sea (AMES)Powered parachutePowered parachute landRotorcraftHelicopterPowered parachute seaGyroplaneWeight-shift-control aircraftWeight-shift-control aircraft landGliderWeight-shift-control aircraft sea
Class ratings may have limitations placed upon them. In the United States, if a pilot being examined for a multi-engine rating does not demonstrate the ability to control an aircraft under asymmetric thrust, their multi-engine rating will be endorsed as "Limited-to-Center Thrust". (In the European Union, a multi-engine centreline thrust aeroplane is considered a single-engine aeroplane when being used for an instrument rating skill test.)
