You are half way through your 4 hour on-line flight from LGAV to EGGL. There has been no ATC available and you decide to leave the room to grab a bite. As soon as you leave your cockpit, ATC comes online. You get contacted via private message, but no answer. You finally get back to your cockpit, you see the message and you get back to the ATC. "I called you 25 mins ago, you are now leaving my airspace".

Let this happen no more! With this simple app, you provide your callsign and you get notified as soon as you enter an ATC controlled area, or as soon as you approach one. You can specify the vicinity to the controlled area that you want to get notified (default 20nm). The application works with VATSIM data servers.
