Pretty good day today. Started out the day filling out my IFR Performance Profiles table. From there I headed west for some navigation and landing practice. Hit a string of airports for four T&G landings with surface winds ranging between 17 and 27 knots. After that turned back to the barn and climbed to 9,500' MSL (no ADS-B Out yet). Pulled back power to 2300 RPM and leaned out to 75° ROP. With full throttle only providing 17.5" MP, fuel flow was a whopping 8 gph!!!! So what did I get for a TAS for that 8 gph? Who cannot enjoy 155mph (135Kts) TAS at 8 gph?
