How many engines does a plane have on average?

Most commercial passenger planes have two engines, while some larger planes may have three or even four engines. The number of engines on a plane is determined by a number of factors, including the size of the plane, the weight of the plane, and the desired range of the plane. Smaller planes, such as private jets and turboprops, typically have one or two engines. Larger planes, such as airliners, typically have two or four engines. Some very large planes, such as the Airbus A380, have four engines.
