According to my Mooney A2-A owners manual.....power on stall speed is 38 MPH T.I.A.S. and power off stall speed is 48 MPH T.I.A.S. Scott A2-A 5458F

To: "'ety Tech'" <[email protected]> Date: Saturday, August 16, 2008, 4:44 PM Small corrections here. The official power off stall speed for 415D, 415E, 415G and Forney F1 models is 56 MPH 56 mile/hour (mph) = 48.662 669 547 knot So there you go. The later style Ercoupes won't qualify for Sport Pilot because a higher gross weight also results in a higher stall speed. I don't have the Flight manual for an Alon, but 45 knots stall speed seems too optimistic to me. The Alon has an even higher gross weight. The only way that an Ercoupe would qualify would be by using the Skyport STC thereby REDUCING the gross weight for later style Ercoupes. Now John, if that would be an option , this would be a good selling STC wouldn't it?

Very nice comparison, thanks for putting numbers to it. As an Alon owner, my interest is in that model. The Alon might make if the performance numbers below are correct (from the Wikipedia article on ERCO Ercoupes).

Maybe not. If I have my performance numbers correct, raising the weight limitations for Light Sport Aircraft alone would not allow C-150s into the market. The maximum stall speed allowed is 45 knots. That is the clean stall speed. It appears that the clean stall speed on the C- 150 is 48 knots (42 knots with flaps). It is not likely that the FAA would change two limitations just to allow C-150s. I think Cessna would be lobbying strong against that given their investment in the FluffCatcher. Beside that, the 415D which would benefit from a high gross weight limitation has a greater useful load than C-150. I have posted a file with a comparison. Frank Nelson N51DV - 415C TOA .
