I've recently been reading
which has been helping me along with some tips on good (but not prefect!) landings.
One thing that I'm struggling to understand is a tip that you pick a point 1/2 mile from your touchdown point as you enter the pattern and then whatever else happens aim to be a certain height (say 400') above this on final.
This seems sensible, but the issue I have is how to estimate that 1/2 mile with any degree of reliability, especially when you're over unfamiliar ground. I could work it out at my home field, but I guess my landings should be ok there anyway. do you use airspeed, or some other technique?
Could someone else who uses this or similar technique give me a pointer?
