Interesting Dafydd, the same speed as Cessna declare for the C150. I used to wonder at the accuracy of the ASI on the J1B, but distinctly remember the first time I flew one, how long it took in the hold off until she settled, it seemed inordinately slow compared to the Citabria that I had many hours in. I noted the ASI was waaaay slow when she sat down. I have always regarded the ASI readings at the hold off and settle to be suspect in all aircraftThe POH that I have sates 25 knots stall, I take it that is IAS, not CAS? The POH also states a full flap short field approach at 40 knots, I assume based on the 1.3 x VS0. I had assumed the apparent slow stall and settle speed was significantly due to the rather large 37' wing span, although at a MTOW of 916kg she is a lot heavier than the Citabria. So if the stated stall speed is so inaccurate, should I assume at 40knots IAS on short field approach that I am also traveling faster than the 40 Knots IAS? Again though, at a 40 knot approach it does 'appear' very slow and uses bugga all runway to stop.
