What!!!
You have just made an excellent technical description of your experience in the PC9, and then finish up with A Civvy Cessna....won't work.
That is utter Bull****!!!
It works just the same, unless the RAAF PC9 is something of a physics exemption.
The difference is just the minima. You obviously never spent the time doing them in a C172 to find out where that minima was. Possibly it is 800 feet too, I do not know. But if that is what I flew I would surely find out.
The same rules apply from a tiger moth to a A380, the numbers are different, mut unless Newtons laws have changed there are only two variables, known tested minima, and pilot training.
The minimum height for success is easily found, training is the stumbling block, and ask ourselves why??
Now any of you Top Guns from the ADF want to answer my Macchi question? Have you gone looking for the accident report? He is a tip......there ain't one. Now think about why?
