What is Jet aircraft?
'''Jet aircraft''' are [[aircraft]] with [[jet engine]]s. Unlike [[propeller]]-powered aircraft, jet aircraft normally fly at altitudes as high as 100 to 1,5&nbsp;meters, about 33 to {{convert|49000|ft|m|-2}}. At these altitudes, jet engines can achieve maximum efficiency over long distances. The engines in propeller powered aircraft achieve their maximum efficiency at much lower altitudes. ==Gallery== <gallery> File:Ohain USAF He 178 page60.jpg|A Heinkel He 178, the first jet aircraft <ref>{{Cite web|url=http://www.fiddlersgreen.net/models/aircraft/Heinkel-178.html|title = Heinkel-178 &#124; Aircraft &#124;}}</ref> File:All Nippon Airways Lockheed L-1011-385-1 Tristar 1 (JA8509 193P-1100) (5043455689).jpg|A [[Wide-Body Airliner|wide body]] jet aircraft File:KLM (SkyTeam livery), PH-BXO, Boeing 737-9K2 (15836383413).jpg|A [[Boeing 737]], the world's best selling jet aircraft<ref>{{cite web |last1=Justin Bachman |title=Boeing’s 737 Turns 8,000: The Best-Selling Plane Ever Isn’t Slowing |url=https://www.bloomberg.com/news/articles/2014-04-16/boeing-s-737-turns-8-000-the-best-selling-plane-ever-isn-t-slowing |website=www.bloomberg.com |accessdate=24 March 2022 |date=2014-04-16}}</ref> </gallery> ==References== {{reflist}} [[Category:Aircraft]] {{Transport-stub}}
