Yep, I can remember my instructor years ago when I was a lot younger reached across the cockpit, grabbed me round the neck and literally said to me ... "What the F*** are you doing, where are you? You are wasting your money and my time. Lets land and come back and do it again next week." ... and we did next week and he said 'That's better now we are back on song". He was a cranky ol bugga, but I still respect him immensely today. He would allow you latitude to get into trouble and see if you could get out of it, but he was always on the numbers with me ... "watch your speed Dave ...", not too steep Dave ... use your feet Dave ... well you saved that one Dave, well done, now you know what you did wrong ...".
He was tough ... when I did my PPL flying test, after we took off he said ... "well you have just failed the test but lets go fly and see why" I had chosen to continue with my PPL test on a forecast of moderate to severe turbulence ... instant fail. Guess what ... that day I learned what that really meant, first hand experience, while we were in severe turbulence he put a diversion on me and that was obviously impossible, so he made his point. When we landed at Albion Park into a very strong headwind, I swear the 172 rolled to stop in about 50 metres. He did all my T/W, CSU, retractable and aerobatic endorsements as well.
As a result to day, I am still critically aware of the things he drummed into me and especially my speeds in the circuit and the setup on approach to land. But above all he taught me that asking for a check flight and some review is an honourable thing to do. And to that point when I do my next BFR and I am gong to ask him to put me through the ringer in every aspect especially in light of recent accident events.
I must admit I am in love with living and sharing life with all you mongrels ...LOL.
