The author of that article needs to realise that not all engines and aircraft perform equally.
I think you'll find that he has quite a good grasp on that, Squawk. You left this off the end of the quote:
Some readers have blasted me on the checklist columns about single-pilot operations, saying "Well, how about the A-26, or the single-pilot Citation?" Folks, there are exceptions to every rule, and if you haven't got the smarts to figure that out, you not only shouldn't be reading this column, you probably shouldn't be flying (or even walking).
(bold added)
But hopefully you've at least learnt that the prop on Mr Deakin's Bonanza doesn't stop just cause the motion lotion runs out? Now ask yourself how many thousands of GA aircraft have similar engine/prop combinations.
In what aircraft type/s have you had it "get quiet", Aero? The ones I've done it in don't.
PS: Yes Eddie. I think Squawk's being obtuse.
