I've often wondered how a failed magneto would manifest itself in flight.

If you don't have an engine analyzer (as Peter did), it shows up as a sudden 50 rpm
or so drop -- just like it does when you're doing your runup.

With the constant speed prop in the turbo'ed Bonanza, prop knob set
for cruise at 11000MSL (instead of full forward on the ground like at
runup), could you really sense that much of an rpm drop? Or would the
change in MP be more pronounced at the sudden loss of a mag?
