L39 Guy:
With WAAS grade receivers, precision approaches to virtually every runway in North America becomes possible and with Galileo every runway in the world.
Not exactly. That's why the U.S. has a lot of LP approaches now, and more all the time. Some runways don't have the clear zones for a vertically guided approach (APV in FAA-speak).
And, ICAO has yet to anoint LPV as a precision approach.
