16 Facts About Aircraft engine


The greatest advantage of an inline engine is that it allows the aircraft to be designed with a low frontal area to minimize drag.

The disadvantages of an inline Aircraft engine include a poor power-to-weight ratio, because the crankcase and crankshaft are long and thus heavy.

On multi-engine aircraft, engine positions are numbered from left to right from the point of view of the pilot looking forward, so for example on a four-engine aircraft such as the Boeing 747, engine No 1 is on the left side, farthest from the fuselage, while engine No 3 is on the right side nearest to the fuselage.
