Airplanes are already using the higher-accuracy GPS+GNSS to land safely on the runway in low-visibility conditions, guided in by the Flight Management Computer. It makes a big difference whether the plane is 5 meters above the runway or zero meters above the runway.

Commercial airliners use a radar altimeter, not GPS/GNSS to assess altitude.
Most if not all airliners equipped with autoland systems use ILS rather than GPS for position as well.

Agreed, but only the big iron. I spent 8 years working for Universal Avionics, who develops precision WAAS-SBAS GPS flight management systems for GA / BizJets: http://uasc.com/home/nextgentechnologies/precisionaviationwi...
