Is every touchdown a stall?

A normal approach is at 1.5 Vs until on final approach to
allow for maneuvering flight. Once on final, where bank
angles will be less than 15 degrees, with little effect on
stall speed/load factor, speed will be 1.3 Vs until
beginning the flare or round out. Actual touchdown will
happen at 1.1 to 1.01 Vs. On really short fields that are
not "soft" actually stalling at 1 to 2 feet AGL and dropping
it in is well within the design limits of the landing gear
and wing.

Real airplanes and real simulators "care" about such
details, desktop PC games and simulators don't, which is why
you can log take-offs and landings in an airplane or a $20
million full motion/visual sim.
