Back when I used to teach science classes for elementary school students and their teachers, we used to say that a great question was one that generated an answer plus two more questions. Such it is with the RNAV (GPS) Rwy 33 approach to Easton, Md.
The question was simple: Why would a GPS approach say “RADAR REQUIRED”? It’s GPS, for crying out loud. We can go anywhere without radar vectors, so long as there’s a safe altitude to fly. Who cares if there’s radar?
