Class rating
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 or multi-engine piston 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:
| Category | Class | Category | Class | |
| Airplane | Single-engine land | Lighter-than-air | Airship | |
| Airplane | Multiengine land | Lighter-than-air | Balloon | |
| Airplane | Single-engine sea | Powered-lift | ||
| Airplane | Multiengine sea | Powered parachute | Powered parachute land | |
| Rotorcraft | Helicopter | Powered parachute | Powered parachute sea | |
| Rotorcraft | Gyroplane | Weight-shift-control aircraft | Weight-shift-control aircraft land | |
| Glider | Weight-shift-control aircraft | Weight-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".
