Thanks 'bird and Nuts
We pilots must remember that rate of climb is the delta between thrust available and thrust required for the AoA and weight and...... ( power required)
It's why the nasal radiators tend to use throttle for glide path rate of descent to land on a boat. They trim for an AoA/speed and control the flight path with power. Just look as the Asiana fiasco, much less this one we are re-hashing.
Besides going well below the planned altitude, and a screwed up approach, the power side of the equation was not even close to what was required to "save" the screwed up flyby. Sheesh. I don't like being harsh about a fellow pilot, but this one really bugs me, and I am thankful that so many folks walked away from it.
Lastly, who in the world on the sidelines would have appreciated a high AoA, slow speed, extremely low altitude flyby? I'll bet 99% of the witnesses didn't have a clue about what the pilot was trying to demonstrate.
