Why are some VOR sites missing from the Java Tools?
ADDS does not have a full list of all VORs. What we term VORs are actually just a subset of “high-level waypoints” and are the sites which the Aviation Weather Center uses for the points to describe AIRMETs and SIGMETs (and the same points the Storm Prediction Center uses to describe convective outlooks and severe weather watches). It is on our todo list to get a full list of VORs.
