this paragraph came about because of the line you previously proposed essentially saying that RTCA SC-159 appreciated the fact that GAST F was an extension of GAST D. Again the RTCA folks basically rewrote your sentence to reflect their perception of where
WG 4 was on the issue. I think with your added sentence it pretty clearly captures the discussion now.<o:p></o:p></span></p>
