Two; there may be more :

Using rudder to put a distant target between our legs aligns the longitudinal axis regardless of seat position. This can be used to put the aircraft down aligned with it's direction of travel.

Distant targets appear to close with us slowly, regardless of our airspeed , until we get lower and closer. This can be used to make our airspeed reduction prior to the desired touchdown point rather than after. We simply stabilise the apparent brisk walk rate of closure. The advantage is that we can be fast when high and distant, yet slow when on short final. Very safe. Very efficient. Very easy. No instrumentation required. Win win win win.

If you read the first one in your "Happy Birthday Mr. President" voice it really sticks!

-or maybe I'm just high and distant because I don't understand the second one at all. We are supposed to look at something close and come to walking speed right before touchdown instead of after touchdown?

"By George! I think they've got it.

This one isn't useful but is an interesting optical illusion. My wife snapped this photo from our little fishing boat on Rimrock lake last summer.

Not to hijack the post, but we lived in Yakima for a couple of years in the 80's and when we left they were draining Rimrock (1988 maybe?) for irrigation during a particularly dry year. They were netting Kokanee with a purse seine that was driven over the pass from Seattle and airlifting the fish by helicopter to the next lake up to try to save them. I always wondered how it all went. Does anyone remember?
