You didn't mention MacReady, wind, safety altitude and field altitude.

I've noticed on my SN10 that the final glide height
needed is excessive. I'm comparing it to GNII driven
by a 302A. The GN setup is faultless and the SN10 can
demand twice the height needed as calc by GNII.

When I flew on Saturday, the Ilec needed around 8000
ft and GN said 4500 feet, GN was correct. Roughly 45
K glide, Ventus C.

I remembered to set the wind on the Ilec, distances
looked right, winds on Ilec and GN agreed.

Any ideas ?
