Researchers found that when planes fly in the conditions which make condensation trails, which is the right mix of altitude, humidity and temperature, those frozen ice cloud-like streaks in the sky actually trap a surprising amount of heat in our atmosphere. One study published in February, 2020...
000 feet in order to take advantage of one. By flying in a jet stream, planes traveling from west to east get a significant boost from the tailwind, which saves time and fuel. Conversely, planes flying in the opposite direction lose time and expend more fuel...
Johan, there is no one “cruising altitude” that ALL planes fly at. The plane’s altitude is set by air traffic control (although the pilot can request a new altitude). Individual jets have a “cruise altitude” which gives an optimum fuel efficiency, and obviously they would prefer to ...
