With the various definitions floating around It's a bit difficult to put a finger on what exactly constitutes a Frise aileron. My understanding has always been that one element of a Frise aileron is that when the aileron is deflected down (on the rising wing) that some airflow is directed from the underside of the wing to the top surface of the aileron, much like when a slotted trailing edge flap is extended. I don't think that happens on a 172 aileron, so it wouldn't be a Frise aileron in that regard. The ailerons on the 206, however are. they are more of an airfoil cross-section, and they are hinged at pivot points well back of the aileron chord vs the piano hinge of the 100 series Cessna ailerons.
