Flew in one of FlyBe's Dash 8 Q400's today and took a Garmin foretrex GPS
with me. I switched it on and was surprised to see 480mph !!!! - altitude
and distances were perfectly OK, never ever had any problems with speed
before, in car, or on other aircraft. I was a bit surprised to see that a
prop can do 480mph though, that's got to be a world record ?? no ??. Can
this be right ????.

I don't think the GPS was wrong as it had locked onto quite a number of
satellites and was showing no other erroneous readings, it showed a steady
480mph !!

presumably there was a significant tailwind. Apparently, in the days of the D.H. Trident, those types used to do marginally supersonic groundspeeds on the London-Rome route with the aid of the prevailing tailwinds.
