Yes Steve. Your point is quite valid in the sense that if you know the kind of linkage, then the dependent variable can be deduced from the independent variable by applying the link kinematics or relationship.

Problem in this case is, till Nelson pointed out nobody ( including the client ) guessed so. Maybe it is so.The linkage to the blade pitch mechanism is quite a complex one with cranks and bevel gears as the adjustment has to be uniform on all three blades AND when they are rotating - so it kind of was a black box stuff. So thats the real issue. Nobody knew what was the final transfer function between the Blade angle and the pitch cylinder stroke...
