Hi peter kent
I rebel against illogic, and squishy nomenclature. The potential for mistaking a value of lift should not be dependent on a formula that is merely an arbitrary definition.
At the point where an airfoil begins to develop lift becomes my datum. Zero means zero, or should. Just a quirk of mine, but not just me. It is an accepted datum in the industry,
There should not be confusion, and associating "Zero" angle of attack with actual work does just that. I prefer to let the design drive the nomenclature, not the reverse.
No problemo, peter
