How long would it take a jet airplane to travel around the earth?

Answer 1

The earliest time to get around the world is 80 days

Different jets would have different speeds, and there would have to be layovers for refeuling. I estimate that an average jetliner could do it in two to four weeks, and a Concorde could do it in less than a week. An SR-71 could do it faster than that, with aerial refeuling from a KC-135 tanker. Even still there are layovers, as the SR-71 must slow down to refuel from the subsonic KC-135.

Also, how far north or south from the Equator are you? The closer you are to the poles, the shorter the distance, and the less traveling time around the world. Only by circling the earth at its widest are you truly going aound the world.

Answer 2

That's a tough question to answer as stated. The speed record for a jet aircraft (B-1B) to circumnavigate the Earth with in-flight refueling is about 1015 km/h. If you want to know how long it would take to fly around the Earth at the equator at that speed, we divide 40076 km by 1015 and we come up with about 39.5 hours. (It would actually be longer as the distance is a sea level distance, not at altitude.) Has anyone actually flown that route? I don't know, but that would be the minimum time such a feat could be achieved with the current technology.

Answer 3

Considering the earth's radius to be about 6400km & the jet plane's speed to be about 800km/h (both are very practical approximations) it woulkd take about 50 hrs to do it.. Distance = 2*pi*r=2*3.14159*6400 km Speed=800 km/h Time=Distance /Time ~= 50 hrs. It should be noted that the time will also be dependent on the crusing altitude, high altitude winds, bad weather and of course the curvature of the earth. Earth is bulging at the equator.

Answer 4

It depends on the type of plane ....

Answer 5

42 hours

Answer 6

39.5 hours
