Flew in very hot (100 F) weather last week with Young Eagles program but never got above 6000 Density Altitude. Fuel flow readings normal-- 5.3 or so in climb and 4.2 to 4,2 in cruise at 5200 RPM. Went to pancake breakfast this morning; climbed to 5500 MSL (6620 DA) and fuel flow readings stabilized at 5.9 GPH. After 15 minutes I descended to 4500 MSL (5500DA) and FF dropped to 4.1 to 4.2 GPH. After a few minutes I climbed back to 6600DA and fuel flow readings stayed 4.2! Return flight at 4500 MSL,5500DA. fuel flow at 4.2. Flew 1.6 hours and burned about 6.5 gallons: 4.1 gph.
I still think this is a density altitude problem with the D180. Can you guys going to OSH talk with Dynon people. John, did you ever get any feedback from the data you sent.
