OK Folks, here are some settings that I use to
maximize my range and keep fuel costs low.
10,000'/8.2gph per side,
19"MP/2150RPM/137KIAS/12C. My TAS was around 162KTS for a whopping 9.5 nm/gal.
Not too shabby for a B55, IMHO.
Everyone is usually quite familiar with their
high performance envelope. In these days of >$4.00/gallon 100LL, isn't it nice
to know what the economy end of the envelope looks like?
OK, so I let the altitude go 150' over
assigned. Good thing it was not an ATP checkride, LOL! You can just about make
out the 137KIAS airspeed while I'm at my range extending cruise burn of 16.4 GPH
and running the aux tanks to empty.
