First STEp :BUY STICK AND RUDDER
step one, buy "STICK AND RUDDER", read the book, memorize it...detailed information on judging height and more.
two...go to a department store with escalators...go on the ''down'' escalator many times...you are in effect on a glideslope to a touchdown...you will learn the same sort of timing for landing as the feel for getting off the escalator correctly.
think of landing as taking an automobile to a stop sign and not over shooting or undershooting the stop...its energy management.
I taught in the PA38, many, many hours...It is very hard to trim correctly for the approach speed for one person in the plane.
so, make sure you do a weight and balance and make sure you are in proper envelope...I mean it, you might be at the forward edge depending on fuel and ballast.
go out and fly the plane in the landing configuration and get an exact speed of stall and see if 1.3 times that speed (with full flaps) is the approach speed in the book.
ask someone if the runway slopes uphill or downhill and let me know.
AND GO OUT AND BUY AND READ STICK AND RUDDER BY WOLFGANG LANGWEISCHE.
fly as much as possible at safe altitude in the landing configuration at approach speed and see how it feels...do this with at least 3000' of altitude above ground and with a cfi.
