Those of you that were flying around Friday and were IFR or VFR in the class Bravo airspace heard a new call sign called "Potomac Approach". The Dulles sector was the first to move to the Vint Hill facility and "Dulles Approach" no longer exists. There was a skeleton crew in the Radar room at the Dulles tower just in case something went wrong, but nothing did. Frequencies are still the same and many of the people are the same too, but you will only hear "Dulles Approach" if someone makes an error ;-) More at: <A HREF="http://www.faa.gov/index.cfm/apa/1062";>http://www.faa.gov/index.cfm/apa/1062</A>
