Subject: Pietenpol-List: Ceiling was Westach gaugesIn a message dated 1/27/2006 9:00:11 PM Central Standard Time, at7000ft(at)gmail.com writes:So on a 90 degree day the density altitude is around 10,500 ft. and you are still on the ground! And you're not even in the mountains yet.Rick,That's why I'm searching for the Absolute Ceiling - not the Service Ceiling. The Absolute Ceiling is the point where the wing is at the Critical Angle of Attack the wing will stall if any more altitude is attempted. In addition to the EGT and CHT instruments, I installed a mixture control to keep the engine happy in the thin air. Until I conclude these test flights, I wouldn'teven attempt to get my plane off the runway at your elevation, under those conditions. I will certainly report to the group here, the results of the tests.I'll have my video camera with me. My field elevation is 1360 msl, and It feels like I'm on the edge of space up there !! :)Chuck G.NX770CG________________________________________________________________________________

Gene:Are you running a top mounted carb? if not why the fuel pumps?It was my impression we could run gravity fed w/a Corvair in a Piet setup asper WW, below the engine.Are the pumps necessary because of the fuel cell you are using?what am I missing here?kind regards:Michael SilviusScarborough, Maine.----- Original Message -----
