Is 650mph an unusual ground speed for this kind of aircraft? I had a flight to Syracuse NY which was a bit behind, and the pilot said he hasn't had a ground speed that fast since the Reagan Administration. lol

I think there is an RJ7 pilot here on the forums, but I can answer with confidence, yes that is unusual. you must have been eastbound, I've seen winds over a 130 kts, pushing our rather slow E-3 to a groundspeed of over 530 kts. The faster the better by the way and good fuel economy for the airline.Jeff

that's only 565 kts so about a 95kt tailwind. i have seen 180kt tailwinds in winter with 650kt groundspeeds (750 mph).what stinks is the way back............

Yeah it was eastbound, from O'Hare. Thanks for the replies.

The fastest ground speed I've seen (a photograph of...) was 701 knots. It was a Boeing 767-2 or 3 over China/Japan/Sea of Japan area.Now THAT'S what I call a tailwind.In the sim, 600 knot GS is the fastest I've run intoRhettAMD 3700+ (@2585 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2gb Corsair XMS 3-3-3-8 (1T), WD 150 gig 10000rpm Raptor, WD 250gig 7200rpm SATA2, Seagate 120gb 5400 rpm external HD, CoolerMaster Praetorian

>In the sim, 600 knot GS is the fastest I've run intousually in LOFT you will get a 2-300kt tailwind. had the beech 1900 once doing 500kts in a sim!

ugh LOFTs not fun at all! Especially at 1 AM!

http://www.groundspeedrecords.com/That's a pretty cool site with snapshots from various planes showing their GS. There's one shot of a 747-400 with a 731 knot GS!

Neat site thanks for posting, wow 200kts in a 172!!!!!!
