Fokker 100 impossible speed?

[northstar]

Hi, I'm a total rookie here, so apologies if this question has an obvious answer.

I've been tracking a Swiss Fokker 100 from Birmingham to Zurich, and on crossing the English Channel, the speed registered was 619mph. However, maximum cruising speed of the aircraft seems to be 525mph.

So was it going well beyond the maximum, or perhaps there's some discrepancy somewhere?

Thanks,

Ken

Ken,

Interesting observation. You're right about the maximum cruise speed (see link below) and I cant explain the discrepency other than to say it may have been an anomoly or you may have seen 619 Kph, not 619 Mph as those Rolls Royce Tays would have spun themselves clean off the aircraft long before those kind of speeds. Even if empty I couldnt imagine any pilot who enjoyed living winding her up to about 20% above the max. Just out of interest I've been trying to find the never exceed speed but havent had any luck so far. I'm also checking to see if any have had any form of upgrade that might explain it.

I have no idea if the following programs ever got off the ground;

Hi Gregg,

Thanks for that. Yeah, bit of a strange one this. It was definitely in mph, which gobsmacked me totally! I've also seen this with other aircraft, so it's an interesting one.
