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.

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.
- bb611 9y agoCommercial 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.
