"What is the exact angle between your cockpit = longeron and the top inboard skin of your flap when it is fully up? My plane is a 320."

 

Assuming your plane is a 320/320 and NOT a 235/320, = the correct flap positions are:

 

Reflex (-7 deg.) =3D perfectly aligned with the inbd. fairings.

 

Neutral (0 deg.) =3D 7 deg. down from the = above.

 

Nobody cares what the angle between top skin and = longeron is, the correct datum for all flap measurements is the inbd. = fairing.

 

Best regards
