And so the question is: is it possible to safely
demonstrate competency, say, in recurrent training or
on a checkride for the Fed in a geared aircraft
without trashing the gear box? And if so, how?
Seth,
The economic debate of geared engine vs. direct drive in a commercial
operation is something I'll leave between you and your profit/loss statement.
As far as 135 check rides go in a geared engine driven aircraft, I've taken
many (AC-680E, AC-680FL, BE-80, CE-411) and can tell you with 99% certainty
that the FAA examiner is scared to death of engine cuts and even more scared of
geared engines, in general.
The POI will probably tell you to simulate feather thrust -- which you'll set
up very slowly -- and fly what ever task you're supposed to demonstrate.
It's totally unrealistic, as far as a training and check-ride scenario, but
it's the best both of you can do.
If/when you acquire a geared-Lycoming powered Commander, the collective
wisdom on this email net can give you lots of suggestions on power settings to
simulate feather thrust, depending on what model you end up with.

What would a simulated feather thrust setting be on a 680FL(P) Mr.RPM?

Tom,
With the IO-720, I'd use 14" and 2000 rpm. This is what I've found gave
equal performance (or lack of) to having one feathered on the long body MR RPMs.
If 14" MAP won't keep yours on the governor, you may have to up the MAP a bit.
This are approximate settings, of course. Each airplane seems to have a
different set-up.
