Re: Difference between Approach/Departure & Radar.
Field In Sight,
I'm a controller and I'm confused by the answers provided by my brethern from across the pond.
Anyway, in the US, Approach is used for acft inbound to the primary and or satellite airports, and for overflights.
Departure is used for acft that have departed the primary or satellite airports within my airspace.
Granted I have good Radar coverage where I can see acft on the runway at FWA and I can see them out of 1800 off my satellite airports.
Things are so much easier over here,
Mike
