There are many different types of aircraft on the market. The primary distinctions between them are the mode of propulsion (turboprop or turbojet), the dimensions of the cabin, the number of seats and the autonomy. Airplanes with very small cabin usually have 4 seats and a range of about 2 hours. Then comes a wide range of small, medium or large cabins with between 6 and 8 seats. Between 9 and 12 seats, you have the choice between medium or large cabin business jets. For groups of more than 12 passengers, you can opt for a single aircraft with a larger capacity, or two or three smaller aircraft.
