Landing an aeroplane is like a lot of other activites..once you can do it, the more you think about it, the worse it gets!
Joking aside what you say is quite true which is why I don't really like these 'This is how you land' threads because everyone has their own ideas which involve the most intricate scenarios.
I can land perfectly well. Please don't ask me how though because I genuinely don't want to know. I don't even really think about it when I do it, I just do it. Obviously at one point I was trained how to do it. Being able to do it is good enough for me, I don't need to know all of the scientist stuff.
There was a thread on here not so long ago, I think it was on the subject of when to turn onto base leg or something like that. There were the most fantastic descriptions of angles and speeds; all sorts of wonderful things being bandied around.
I turn base leg when it looks about right. I haven't died yet.
Flying is only complicated if you wish it to be so.
As to the OP, your instructor sounds like a nutter, get another one.
