It is quite usual for the maximum values flown to be found "not limiting" .. ie in the opinion of the test pilot(s), the aircraft could be flown in conditions more critical than those found. I think it nice to treat this as a limit in the absence of further data determined by someone else much more adept than I at evading criticism at the accident enquiry ... </font><hr /></blockquote><font size="2" face="Verdana, Arial, Helvetica">A fair point, but very limiting in some cases, as it seems the manufacturers can choose to write the lowest possible value in the POH. For example the Mooney 201 (Vs0 55 kt) has an 11 kt demonstrated crosswind component, exactly 20% of Vs0 which is the lowest value permissible. The Mooney has never been a nice aircraft to operate in a crosswind, but an 11 kt limit would render it almost completely useless in many places.
