Hmm, nasty enough? Eff = (16*h / b)*(16*h / b) Oe = Eff*Eff/(1 + Eff*Eff) (where 0 <= Oe <= 1) D = q_infinite * S * (CDo + 0e * ( (CL*CL)/(pi * e * A * r) ) ) D: decrease in drag h: height of the wing above the ground b: wingspan :-0 Erik _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
