weight affecting AOA...

John,

Thanks for your correction, was getting a bit mixed up late at night after a tiring day. Feel stupid to have made such a silly mistake...

I was thinking of weight affecting the angle of attack for a given speed, higher weight = higher angle of attack.

The system I designed was also to be used to set best L/D and other speeds which depend on AOA - which will of course give a differing airspeed and pitch angle if the weight is changed for a constant angle of attack. Conversely, if the speed and power are set, different angles of attack will be seen depending on the weight. Please do correct me again if need be.
