    I'm on Flightradar24 right now watching a line of planes from Japan/SK heading up to Anchorage Alaska over the Pacific. The fastest one is a UPS 747-8F listed as going 772 MPH (671 Kt) at 33,000 feet.

    I didn't even know that was safely possible for a commercial aircraft. Do you think it's a mistake, or do you think it's pretty accurate for Flightradar24?

    EDIT.....no joke....it had a black line behind it and now it's just dropped off the radar.

    I thought I saw a NYC to London flight went 800 mph due to a rather stiff tailwind recently.

    So the fastest listed one now is UPS61, a 747-4R7 Freighter, listed at 33,000 feet and 653 knots (751 MPH). That seems either a mistake, or a hell of a tail wind.

    FedEx 777 behind it going 754 MPH...again, that is according to FR24.

    All of the planes on this route are listed well above 600 knots. That must be a hell of a tail wind, or it's an error in the system.

    I just checked a few of the planes passing in the opposite direction....all below 500 knots. So it must be a tail wind for the faster North-bound planes.

    As I recall, the flight from the US to China (direct from Atlanta - now no longer offered) was 16 hours, but the flight the other way was only 14 due to prevailing tail winds.

    Philippine Airlines Boeing 777-300ER.....765 MPH. *******!

    Forgive my ignorance....what exactly does this mean?

    Sounds like you're reading GROUND speed. They could have a tailwind of say 200MPH so the AIR speed is that much less.

    At 34,000 ft the wind is roughly out of the west 250° at 71 knots (about 82 mph). It looks like further to the Southwest around the Aleutians winds are out of the Southwest at 91 knots (about 105 mph).

    That's ground speed, not airspeed. They're riding on the winds aloft, which can get pretty high and are generally out of the west. Miserable slog when heading in the opposite direction, though.

    Philippine Airlines Airbus A350 down near Japan....766 MPH at 37,000. :alex:

    ooooohhhh, yeah I am reading ground speed.

    Okay. This is all irrelevant then.

    :frown:

    Got it, thanks. You can tell I aced my Science classes. :freak:

    No worries. It's not something you would think about on the ground but it's essential up there.

    Yeah I read that. Thats like faster then sound right?

    Going the other way, on a C-5 from Turkey to Dover AFB, I read about 6 books.

    LOL - no worries - it's not necessarily intuitive, especially if people are used to things like cars and driving. The ground (other than sometimes in CA) usually stays stationary. Getting someone's head wrapped around the concept that when aloft all the airplane cares about is that it's moving at some speed through the air, and that the air it's moving through is usually ALSO moving, and that this air movement affects the airplane's movement relative to the ground can be a challange. What it's doing relative to the ground is based on the winds aloft - the plane could be moving backwards if it's flying upwind slowly and the winds are strong enough.

    Being moved by the wind can get pilots into trouble as they get closer to the ground if they start paying more attention to groundspeed than airspeed. Neophytes flying downwind close to the ground with a stiff tailwind who start slowing because they 'feel' like they're going too fast can stall a plane. One of the commandments of flying is 'maintain thine airspeed lest the ground arise and smite thee'.

    I fly Airbus a320, this was on my flight back in November. Ground speed 612kts, true airspeed 478kts, tail wind from 306 @144kts.

    In a strong headwind an oldie like a luscombe or Taylorcraft Can hover or fly backwards. These have top air speeds below 100 mph, low stall speeds. But not recommended. As a boy I haunted the local airport and saw these first hand.

    3glkdog, thanks for the pic. For the unfamiliar GS = Ground Speed, TAS = True Air Speed.

    I've done this a few times doing slow flight in a C172. We had 50+ knot winds aloft and GPS was showing about 5 kts backwards.
