A C150 will do 300 Kts with enough of a tail wind, so what? Boasting about ground speed with tail wind is like telling people how tall you are while standing on a pile of books.


<<I noticed that Columbia Aircraft has formed a "300 Knot Club" for those flying the Columbia 400 at 25k feet lucky enough to find a 70 knot tail wind and take a photo of the ground speed on their GPS.>>

Brent, et al,

 

I am in the 300 Not Club, buoyed by the hot air often emanating from those that said, "You're not going to fly in that thing?"  But seriously, those of us short on engine equipment have to stand on something to keep above the pack.

 

KARR --> Tampa Executive (3FD1) at 9500 MSL, WOT, 2500 RPM, LOP (8.2 GPH), covering 870 NM in about 3:26:00 (flight time above 30 Kts), using 30 gallons for 29 NM/gal at a GS of 242 Kts.  Probably a record for a NA 320 CI engine powered heavier-than-air vehicle.
