1927 Posted April 25, 2014 Share Posted April 25, 2014 Need help to settle a light hearted argument with my partner... Our flight from London was 10 hours - on way back from BKK was 12 hours ... Is it just down to perhaps flying into a head wind ? nothing to do with the world actually spinning ? Link to comment Share on other sites More sharing options...

Popular Post Tywais Posted April 25, 2014 Popular Post Share Posted April 25, 2014 Actually both, wind and indirectly rotation. Can you please tell me what factors cause airplane times to differ between travels to east and to west. It's interesting that you ask this - I am directly experiencing it right now as I sit on an airplane from the UK. It took 5 hours to go West-East on this journey, but is taking about 7 East-West. The reason for the difference is a atmospheric phenomena known as the jet stream. The jet stream is a very high altitude wind which always blows from the West to the East across the Atlantic. The planes moving at a constant air speed thus go faster in the West-East direction when they are moving with the wind than in the opposite direction. Every planet has global wind which are mostly determined by the way the planet rotates and how evenly the Sun illuminates it. On the Earth the equator gets much more Sun than the poles. resulting in warmer air at the equator than the poles and creating circulation cells (or "Hadley Cells") which consist of warm air rising over the equator and then moving North and South from it and back round. The Earth is also rotating. When any solid body rotates, bits of it that are nearer its axis move slower than those which are further away. As you move north (or south) from the equator, you are moving closer to the axis of the Earth and so the air which started at the equator and moved north (or south) will be moving faster than the ground it is over (it has the rotation speed of the ground at the equator, not the ground which is is now over). This results in winds which always move from the west to the east in the mid latitudes. One source here - Cornell university 8 Link to comment Share on other sites More sharing options...

Farma Posted April 25, 2014 Share Posted April 25, 2014 Chivas, it might be the time of the year. My recent BHN - BKK flight only took 5 hours 50 when it usually takes over 6 1/2 hours. The trip back took 7 hours 20. Link to comment Share on other sites More sharing options...

ultimate weapon Posted April 25, 2014 Share Posted April 25, 2014 Was the op in a rush to get to his work place? Flights get delayed all the time and who knows perhaps it takes 2 hours later to take off from the thai airport compared to the UK. Link to comment Share on other sites More sharing options...

ultimate weapon Posted April 25, 2014 Share Posted April 25, 2014 One thing i think everyone missed out was on the argument OP had with his partner. Suffice to say both of them had differing views on why the plane flight back to the UK took a longer time and i am willing to bet it had nothing to do with the jet stream and other such scientific theories. Hey OP pls share with us what you and your partner's viewpoints were on the longer flight back. Link to comment Share on other sites More sharing options...
Mr Worldwide Posted April 25, 2014 Share Posted April 25, 2014 The advertised flight time and actual flight time always seems to differ. The pilot will often say there is a tailwind so the flight is going to be shorter and vice versa. Noted the above about the jetstream but as far as I know the jetstream moves off towards northern Europe and doesn't influence conditions over India and on to Bangkok.

KhunBENQ Posted April 26, 2014 Share Posted April 26, 2014 (edited) @ultimate weapon: what an utter BS, very poor. -------- Checked yesterdays flights (25 APR), two of which have landed already. (scheduled dep. actual dep., scheduled arr., actual arr.) LHR - BKK TG 911 12:30 PM 12:33 PM 6:05 AM 5:40 AMBA 9 3:40 PM 3:40 PM 9:15 AM 9:06 AM TG 11:07 h BA 11:26 h Scheduled time for both flights 11:35h. Schedule time for the BKK LHR direction: 12:05h (less difference than I expected). Completely expected due to the jetstreams. Sorry, but I doubt the 10h flight duration. http://www.flightstats.com/go/FlightSchedules/schedules.do http://www.flightstats.com/go/Home/home.do My worst flight was Bangkok - Warsaw 12:20! for a much shorter distance. Flight speed went down to 7xx km/h due to the strong headwinds. Quickest flight was Munich - Bangkok, 9:30h, 747 reaching up to 1000 km/h. And: some flights back to LHR might simply be late/longer due to traffic congestion at LHR? On the other hand, I compared TG flight Bankok to Munich (daytime flight, 25 APR): departed 15 min late, landed 44 min late. Absolutely no traffic congestion at Munich in the late evening. So really winds seem to be bad at the moment. Edited April 26, 2014 by KhunBENQ Link to comment Share on other sites More sharing options...

Currently it is very far south and does influence these routes.

how241 Posted April 26, 2014 Share Posted April 26, 2014 Headwind +1...correct answer....also could be a delay in getting clearance to land and they 'stack up' the planes. 1 Link to comment Share on other sites More sharing options...
