Such as the need for local transmitters at every airport. LAAS requires this,
and since WAAS cannot match ILS precision, LAAS is required if ILS is to be
fully replaced.
Perhaps you should use some of your vaunted research skills to see what
the accuracy of WAAS is. It's better then a ILS and the WAaS approachs
have the same minimums as the ILS approachs.
