Steve Varsano explains why some corporate jets have three engines instead of two. Three-engine models can burn less fuel than comparable two-engine jets, handle shorter runways, and give passengers peace of mind over water. Modern engines are so reliable the extra one barely matters.

Steve, I've noticed that this aircraft has 3 engines compared to the other 2-engine aircraft. Why is that?
It's quite funny, there's 3 engines versus 2 engines, but the 3 engines burn less fuel than most 2-engine airplanes. And the benefits are that it gives you better runway performance, meaning that you could take off and land in shorter runways. Also, flying over the ocean, it gives people a psychological sort of comfort level that you have 3 instead of 2. In reality, these engines are so reliable on all these jets, it's really a non-issue. Most of the new airplanes now, they all have these winglets. They give it better stability. It It gets you climbing to altitude much sooner and it gives you better fuel efficiency. So the combination of those things, you see all airplanes today that are being manufactured have these winglets.
