A Type Rating (Self-Sponsored) is an allowance to fly a certain aircraft type that requires additional training beyond the scope of initial license and aircraft class training.
This is a Rating needed to fly a specific type. As there are many different aircrafts flying very differently they are all divided (Category, Class and Type). A Type is a specific Make and Model like a Cessna 152 or a Airbus 380 the same way your car is a Volvo Or Dodge.The difference is that in the aviation world you need a Type Rating to operate that specific Make and Model.
A Type Rating can take anywhere from a Few Hours To Few Months depending on the complexity of the Aircraft.
