Flying 20° ROP

Post by awash2002 »

On the way back from Lakeland this afternoon I decided to set the engine up in a 20°ROP at 2400 rpm configuration full throttle 2400 rpm lean to peak EGT which at 8000 was 1432 at 2400 rpm then I enrichened the mixture to show a EGT of 1412 or 12.7gph that gave me a TAS of 168kts True I landed at Calhoun with 40 gallons of fuel so I landed with half tanks of fuel at that power setting that was a power setting that my buddy Zach taught me and I am very happy with the results

Interesting. Is that with the 520 or 550?

That is with the IO-520BB 285HP If you do that with the IO-550B you will get 172kts True at the same altitude
