The question of the landing being a stall just inches above the runway has
been debated for decades. I believe it would be fair to say that the
"every landing should be a stall" theory is old school, and more modern
training eschews this belief. This may also have something to do with
today's reality, where there is a high chance you will be trying to make
the best time possible on approach, without getting in everyone's way, so
you will not be on two-mile finals at 60Kt with full flaps. As a result,
it is likely you will cross the threshold with a comfortable margin above
your Vso.

As for the stall horn, as posted above, it is set to sound above the
actual stall AoA. After thousands of landings in small planes, both by
myself and with other pilots, I'd say I hear it about one in three or four
landings. If you have it while you're in the flare, close to the ground,
it's a gooid indication you're at about the right speed. If you don't have
it, but everything else looks good, than so what....
