The very idea that somone could instruct outside the confines of a school with an AOC and Ops manual would have CASA apoplectic.
You simply can't instruct without a multi thousand page Ops Manual or student training folders that make the Yellow Pages look like a single page extract. What CASA be ale to give you an NCN for if you don't have these. I kid you not, I was asked why I wrote, "Recomend for CPL Test" instead of the correct "Recomended for CPL Test".
My god, it would make CASA actually go outside and look at what is going on in the circuit.
Does anyone in CASA actually still fly a plane?
