Thanks Leadie, I was hoping it was something buried deep that perhaps I had overlooked but it would not appear to be the case.
To make things clear from my perspective, I don't believe that a stall should be considered an Aerobatic Maneuver, especially when viewed in the context of Flight Training but as a potential future Instructor whom may have his name appearing in numerous logbooks I do have concerns about the legality of doing so now that the line I mentioned before about "Straight and Steady Stalls" has been removed from CAR 155 and given the current definition of "Aerobatic Flight".
In all honesty, I believe it would be an incredibly brave and exceptionally stupid Regulator whom would try and come after someone for something like this but as far as I can see, if they were to do so for whatever reason, the Defendant would be on shaky legal ground and we are dealing with CASA afterall....
Thanks for the assistance to those that posted.
