I've done some nice landings and some crap landings, but having read the article posted by Kingy, I'm now prompted to admit a bit of confusion.
All this about the touch down point being where the perspective doesn't move up/down the windscreen, doesn't seem to work for me.
The non-moving point is not where your (my?) wheels touch, but the point where I commence the flare. By the time I've lost the excess speed (1.3 * stall), got the nose high (when I really get it right, gulp), then I've floated a good chunk down the runway (maybe 100 metres, plus?), before that gentle squeak from the tyres annnounces the fun's over.
So if I want to touch down at a specific point, then I have to aim a bit
before my desired touch down point, i.e. undershooting slightly.
Having said this, I'm sure someone will now explain what I'm doing wrong.
