I got a huge kick outta the video .. the disclaimers are excellent.
I always flew my approaches using 'Stick and Rudder' principles as a guide.. worked fine.
FBO operator greeted me with 'you here to dive bomb my runway again?' after she watched a few.
Mike (my instructor) told me it was a great system because if the engine failed I would still make the runway.
Paraphrased from 'Stick and Rudder':
When wing lines up with the numbers on downwind, reduce throtte to idle, trade alt for airspeed onto base, then final
.. ideally you should flare for landing right at the numbers without touching the throttle.
Don't get married to the concept or push a bad setup, you gotta be on top of what yer ship is doin and what's happening around you.
I had to add throttle for go-rounds and crosswind components (hi-desert, SoCal) about half of my landings.
That said .. for my final checkride before solo .. the landing was perfect, mains touched down smoothly right on the numbers as she stopped flyin

ya ..I had 7 hours dual by then .. but .. tens of thousands of hours in various sims over the years, mostly Air Warrior
