Minor point. In aircraft engineering, you can interpolate but never
extrapolate, as the saying goes. IOW, given two data points, it's
acceptable to find a third in the middle someplace (interpolation), but
never go beyond or outside the graph numbers (extrapolation). You should
not make any predictions about what's out there. That's test pilot area.


Good point!

The A36 POH provides airspeeds for best glide (110 KIAS) and
maneuvering (chandelles and lazy 8s @ 120 KIAS).

The POH does not specify if this is at gross or some weight less than
gross, so I use these speeds at all times -- empty or not.
