You really need to look at the Lufthansa landing video again. The
sequence is not as you describe. And la te da, I too flew an airplane
for several years that used the crab landing in a crosswind as a
mandatory technique. You seem to think the Ercoupe is the be-all end-
all airplane for crosswind landings and I say it is not, except in
fairly light crosswinds i.e., less than 15 knots.

them for a number of years with a major airline. The reason the wing
down method isn't used in any four engine aircraft is because the #1
or #4 engine, depending on the direction of the cross wind, will
drag. Happened to a friend of mine while making a very tough landing,
low on fuel and thunderstorm in the vicinity. He ended up with a
complete simulator check ride and the feds dogged him for months. Not
fun.

meant. Same rule of thumb, just keep the damn thing in the middle of
the runway, wings level and let id do it's thing. I have a Forney and
the airplane sits correctly, correct height etc.
