AFAIK In most systems if an object is represented by a point location it is expected that said location will be 'near' the center of the object in question. In the case of radar the center point of the 'target's on-screen echo' when extrapolated to account for the 'display properties' is most often close to the center point of the object 'sensed'. < I know it is really much more complicated then this but ... it is certainly closer to the center point then one of the extremities unless that extremity and the center point line up on a vector emanating from the radar > Note this has nothing to do with how FGFS has or will do things but reflects common practice and deviation from this will 'often' have to be accounted for. hence my original 'kludge' comment Cheers Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
