In simple mechanical stick linkages, is there crosstalk between the aileron and the elevator movement?
In simple mechanical stick linkages, is there crosstalk between the aileron and the elevator movement?


In almost all cases, there is no intentional-- or discernable-- mechanical coupling between aileron deflection and elevator deflection.  However in the Schleicher Ka-6 sailplane, the mechanical linkage is designed to raise both ailerons a little bit, effectively increasing washout in the wing, when the stick is far aft.  See for example page 3 in this manual.  Some other aircraft may share this unusual feature.  You can imagine why it is desirable to have more washout in a low-airspeed thermal turn than in high-airspeed cruising flight.
