You (and probably 20 other people here) probably know more about the physics of it than I do, but won't 61 KTS at 2200 RPM produce a longer landing roll after touchdown than 61 KTS at 1000 RPM?

Generally, I'd think so even though 61 kts is 61 kts. You'd probably have to time pulling the power earlier, but with a shallower approach and slower speed, that doesn't leave much room for error, IMO.

I've seen the "drag it in" method and it usually involves a higher power setting coupled with a lower than book airspeed, with the goal of producing even =lower= potential energy shortening the landing roll even further. But I don't think the non-PTS version of the maneuver, even if done in the real world, is what the poster was asking about.

Same. The drag-in method, though it works, like I was saying above IMO it leaves a far smaller margin for error with the potential for touching down short of the runway/aimpoint. Sure, we've digressed from the original thread intent, so to track it back, I agree with the helpful methods to teaching the steeper, obstacle approach.
