Today's weight/gross weight, find the square root of that, multiply that by the published Vspeed, and you have the new Vspeed.

For example at 750kg, Vs=45

:hmm: Really? I learned to fly on a 5800hr P92 of which 5700 of those hours were all PPL training. Seemed to hold together well, even after 20 or so of my magnitude 8 landings.

Mickey,
I disagree. Not only are Tecnam's wonderful flyers, they have earned a reputation to be cheap to operate and maintain. I know a flight school that uses P92's. Over 5,000hrs of time,...
