Further flight experimenting with slower prop, lower MAP and LOP at lower fuel
flows.
August 4th, Westbound FL220.
MAP 32.0 RPM 2340 FF 16.5 gal/hour (LOP) yields TAS 246.
In the past, at a more aggressive setting immediately after take off: MAP 34"
RPM 2500 FF 19.0 though out the flight, I would show TAS ~245, roughly the same
TAS. Improved prop efficiency?
At MAP 31.5" RPM 2350, the FF is 16.2 and the performance is roughly the same.
At this cruise setting, with a WOT RPM 2680 climb to the flight levels, the
plane's range increases to six hours (rate than 5.5 hours) and still travels
1100nm in five hours on a 110gal full gas load.
Comments welcomed.

Bonus: light winds over the Rockies
