The only people bitching and moaning about long flight reviews, are probably the remedials that need the extra time. The things flight schools wont ever say to a "customer" is that you are crap. But I can guarantee you, just like any cross section of a community, some of us are awesome, some of us are middle of the road, and some of us are absolutely rubbish (same goes for instructors). Strangely the ego levels don't match the reality.
Just because you have a few hundred hours and own your own aircraft does not make you king, in fact it puts you right in the middle of the worst statistical group for deaths and accidents/incidents in Australia. Thats why CASA are targeting you.
Here's the thing.. If you had to put your name to someone's proficiency, have a think about exactly what that means. If you go out and royally screw up or worse, CASA will come looking for the instructor/s putting their ARNs on the line.
You can tell a lot about a pilot by the way in which he turns up and his basic preparedness, but people do the strangest sh1t under what they perceive as pressure, and if thats all we have to go on and see, we're not ticking all the boxes and you need to do more work.
You will never hear it spoken of like this in your flight school, not to your face anyway, but take it from me, behind closed doors, conversations like this will take place, and its not to be a pain in your butt, or fleece you of dollars, but to do our job (which is to make you a better pilot if we can), and protect ourselves legally.
If the industry paid instructors more, you'd be able to keep people who actually give a sh1t about standards and want to see things lift, stay in the game, but the good guys tend to move on, and the industry is filled with guys who see it as a dirty job they need to do to get in the left seat.
