Is there a way to contact ATC when it doesn’t show up on the map or in the ATC button on the bottom of the screen? Earlier, I was flying to KBWI, and when I got within the airspace, Approach informed me that I “was in an active airspace, contact Approach”. However, I could not find the approach frequency anywhere, so after the warning was sent to me 4 times, I ended the flight. What’s the best way to solve this?
Any help would be appreciated.
