I,v not got to the bottom of what the exact data that will be required by mode S but it seems that it will be along these lines aircraft ident , ALT ,IAS or TAS , HDG (track ?).
As soon as i can I,m going to get hold of the installation manual for the King mode S transponder and look as the interface options it is only then that I can evaluate the true impact of this on the private end of the GA market.
The digital input that i refered to in my last post on this subject is to get the data into the mode S unit from the aircraft systems for exampel the most common remote compas system in GA is the King KCS 55 and that,s HDG output is an anolog syncro system that has to be converted to a digital system even for King gps units to give a "HDG up" map display.
The bendix king web sight for europe shows the new mode S unit so the technical data shold not be to long in showing up but i dont place much faith in the glossy sales handouts as the sales people tend to hype up the product (To be fair king less than most)but as with all these systems the devil is in the detail and you will only find that in the technical manuals.
