Full Stall Landing?

In my opinion the use of the term "Full Stall Landing" is a misnomer. At
least for me the term "Extreme Slow Flight Landing" would be better. I
don't put the wings into a full stall before touch down when I land as slow
as possible. I put the airplane on the edge of the stall and fly it to the
ground. I also use feel of the airplane more that airspeed.
This works for me. Maybe others attempt and get a full stall before
touchdown.
I full stall my Mooney. Wheels touch when yoke is at stops.

Very few airplanes will reach stall angle in the landing
attitude. The gear won't allow it. Most pilots are seeing sink, or at
most, partiall stall, not full stall. It's proven when a sudden gust
lifts the airplane clear of the pavement just after touchdown even with
the nose all the way up.
The AOA would need to be 17 or 18 degrees to reach stall.
Measure your wing chord against level with the tailwheel on the ground
or the tail of a trike just clear of the ground, and you'll likely find
something like 12 or 15 degrees. Remember, too, that the stall speed
in ground effect is considerably lower than the book value.
I did some quick and dirty chord angle measurements in the
hangar. The Citabria has 12 degrees in the three-point attitude, and
the 172 has 14 at the root and 12 at the tip with the tail right on the
ground. With the flaps down there's 25 degrees at the root. So the wing
would stall inboard if the tail was really close to the runway, but the
rest of the wing is still flying.
