Bloggs, I gotta object to this mindset:

"Fly it like the autopilot flies an ILS. You get low on slope, you pull the nose up. Primary effect of controls. If you then get slow or know form experience that you will get slow, put the power up. As you say, pitch and power work together, but the initial reaction is to stay on-slope with the stick, then compensate (if necessary) with the power."

Isn't that EXACTLY the mindset that crashed Asiana, and AF447 as well?? They went with "pitch first for altitude" and got behind the curve. And then got confused because "it always worked before" or "that's what A/P does". When in the Asiana case any goose of engines FIRST, anywhere between say t-120s and t-20s would have made the runway. Instead they're in your "power second" mindset (at 3am circadian time) and don't get to the power until like t-7s, fatally late.

And of course AF did go full power but rode all the way in behind the curve without EVER releasing pitch.

I'd go with a much simpler phrase: Power good, pitch bad. Much safer to attempt G/A with (because of) excess energy than the way Asiana attempted their G/A.
