Jan - yes I would agree point 3 is controversial - and I did wonder whether to include it. If you have piloted from the right seat you will know that the perspective looks a little different - the first few hours quite a bit different. However you really start to notice the difference half way down final AND you notice it far more if you are flying the aircraft rather than watching someone else flying. (or at least that is my experience). For that reason I included 3 because I have found, and found myself, that it was very helpful. Ask a pilot who has never flown an aircraft right seat before to fly a circuit, approach and landing and 9/10 will fly the circuit and top of the approach fine - it only then starts to get a little ragged in my experience.
It may well not suite everyone, and, for those who have tried, you might have found it was unhelpful.
I would be interested to read others thoughts who have tried.
