So what are you suggesting, Vessbot? Half a dot low, push the power up? Wait a few seconds to see if it was the correct amount? Meanwhile, you've just landed short. In an Airbus (as Vilas pointed out) nothing happens because there is no pitch-power couple.
I wonder if the FO was doing that in this incident?

As the freighter approached Runway 05L, it appeared that the altitude was higher than the approach glide path. While the altitude got corrected immediately, at around 137 feet the aircraft again began to fall below the glide path.
Investigations revealed that the co-pilot had failed to maintain the normal speed and rate of descent by utilising pitch control and thrust. He failed to determine his mistake in time, which led to the hard landing before the touchdown point.
I agree with Vilas; AOA has nothing to do with this discussion which is now going off on a AOA tangent. Speed is what we see in the cockpit. You pull the nose up a bit, you might have to increase thrust. Might. You pull it up a lot, you will have to. But you don't teach people to fly by using the power to stay on the GS. Maybe in a 737, but not in anything else.
