[Leica] IMB: TBM 850 at the Airport

[Jim Nichols]

Thanks, Ric.

Yes, once you get above about 200 horsepower, most props take off at 
so-called flat or low pitch to allow use of maximum horsepower, then are 
advanced to greater pitch for best efficiency at higher speeds.  There 
are tables and curves for best combinations of pitch and rpm, depending 
on your objective, i.e., speed, endurance, efficiency, etc.

This airplane is listed as having a 700hp Pratt & Whitney turboprop, a 
nice performer.
