Hank Posted January 30, 2016 Report Posted January 30, 2016 I get 143 mph Indicated at 10,000 msl in my C (172 mph true, or 149 knots). Several panel shots here show this. The only time my groundspeed is above 140-ish knots, it's due to a tailwind. Like my flight just before Thanksgiving, where I leveled off here at 9000 msl and 164 knots, and before descending towards the ILS into KFAY almost two hours later it was showing 186 knots. I'd love to see how you routinely get more speed from less power at those altitudes. Cruise power for me that high is 2500 and leaned to peak or a few degrees above. If I go the few degrees below that I can get now, speed falls off pretty fast. My climb rates WOT/2700 above 10,000 are pretty poor, too.
rbuck Posted January 31, 2016 Report Posted January 31, 2016 At higher altitudes, 11000-12500, I normally get about 145 indicated. (150ish kts). I usually do a little better at mid-altitudes, but I don't usually indicate above 150mph much. 145-150mph indicated is standard. I flight plan for between 150 and 160 mph true, depending on my altitude and settings.
