Landing on undulating runways
I'd be interested to hear from anyone who regularly flies into a field with an undulating runway. I suppose I'm talking about anything from an Elstree-style runway (the initial dip on 26 followed by the upward hill) through to private strips on ground which is not flat. I'm not talking about a constant up-slope or down-slope, nor about bumpy runways, both of which I can handle - I'm specifically interested in fields with several rises and falls over the course of the runway.
The reason I ask is because I visited Elstree for the first time last weekend, and found it extremely tricky. I made two landings there, both pretty much identical. Because it was a bumpy day, I was keeping my speed up a little bit. I started off by being high over the trees on final to 26. This made it difficult to get the speed back. I rounded out over the numbers, but then floated a short way down the runway due to my excessive speed. And that's where it went wrong. What happened, I think, is that I maintained a constant height relative to the far end of the runway (where my attention was focused). As I drifted down the runway, I reached the start of the up-slope part of the runway, and the ground rose to meet the aircraft. This resulted in a main-wheel first landing, something which every tail-dragger pilot knows is a bad thing (unless a wheel-landing was intended of course).
So any advice from pilots who handle this kind of thing regularly would be appreciated. Where exactly do you focus your attention in order to ensure that you remain at the correct height above the bit of runway you're currently overhead through the flare? Any Elstree pilots care to comment? And I'm sure there are many fields which are far more tricky in this respect!
Thanks!
