Notes:We were on a non-stop flight from Tampa (KTPA) to Montreal Mirabel (CYMX) at 25000ft over the Delaware Bay with a 159Knot tailwind! At normal Cruise Power and level flight we peaked at 360 knots, with speeds well over 300 knots for a good portion of the flight. We completed the flight in 4 hours 28 minutes which I'm sure is a speed record between those 2 city-pairs in a light plane!
