What engines are on a Boeing 747?
The 747 was the first airplane dubbed a “Jumbo Jet”, the first wide-body airliner. The 747 is a quadjet, initially powered by JT9D turbofan engines, then GE CF6 and Rolls-Royce RB211 engines for the original variants. With a ten-abreast economy seating, it typically accommodates 366 passengers in three travel classes.
How are aircraft engines numbered?
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.
How do I identify a Boeing 747?
The wide-body Boeing 747 is an easy spot with its bulbous front fuselage, four engines under the wings, one full deck the length of the fuselage, and one partial deck on the front. Shown below is a side-by-side comparison of the Boeing 747-8F to the Antonov An-124-100, both wide-body jet freighters with four engines.

Can a 747 fly on 3 engines?
Conclusion. While it’s very clear that a 747 is unable to properly fly with the failure of three engines, we can see that a single functioning engine would at least extend the aircraft’s distance and prolong its time in the air.
