AMF-that was an excellent explanation of how to use the ATC system in the northeast. Many airports have so much traffic, even far from that area, that you must always question whether you were switched to tower freq. Scanning the two or three tower freq's on the approach chart can help us decipher which one, when they blurt out "contact 118.3 over 'Mafia' (at ORD)". So long Meigs Field.
Considering the number of airports in a small area, how does the number of high-performance aircraft movements per day compare with northwestern Europe? Say, between Brussels and Frankfurt etc?
