RV10 Real World Performance at Various Altitudes
Finally got an oxygen bottle for higher levels. So, took the 10 up today to see how it performed at various higher altitudes. I have a standard compression IO-540 and 2-blade Hartzell prop. Tested at 8,500 / 10,500 / 12,500 / 14,500 / 16,500 and 17,500 all running lean of peak @ 2,400 rpm and WOT. I was surprised how little KTAS degraded at the higher altitudes (from 169KTAS to 162 KTAS) and it performed equally well from 8,500 to 12,500 ft. It seemed to be happiest at 12,500 with lower GPH fuel burn and 168 KTAS.
Also surprised how efficient it got at higher altitudes. At 17,500 Garmin showed 19.5 statute miles per gallon! Here's pics of the performance at 2,000 increments....
