Jim, if that modelling is only using simulator data, surely it is only valid if those same test points that provide that data have been taken from the manoeuvres flown in the real, test-instrumented aircraft.
Obviously the condition I am most interested in is the OGE hover since that is what us SARboys do a lot of and, as seems to be the case, there is no specific data in the RFMs for that condition, just a generic manoeuvre (amount of nose-down, duration of attitude and target speed) which is more likely to be applicable to rig work or Cat A (or whatever the latest name for it is) performance.
Jim the HEC D you talk of is presumably a limit on AUM to ensure that effectively an aircraft is SSE in the hover if winching is being conducted - such limits do not apply to us nor, if I have got my information correct, would they apply to civSAR on a rescue since they only have to consider aircraft performance (in public transport terms) once the rescue is complete.
