Controlled airspace alerts provide instant access to crucial frequency information worldwide. Radio frequencies are displayed as you approach an airspace, eliminating the need for in-depth airspace information searches.
You can optionally hide the airspace frequencies or customize the alerts in other ways in Map Settings> Alerts > Airspace & NOTAMs.
Controlled airspace classes A, B, and C show all associated frequencies besides tower and any secondary frequencies.
Classes D, ATZ, and MATZ only show tower frequencies.
Airspace class TMZ will show the squawk code and the frequency.
