What happens if you do not open your atc window in FSX?

If you do not open the ATC (Air Traffic Control) window in Microsoft Flight Simulator X (FSX), you will miss out on important communication and guidance regarding your flight operations. This includes receiving instructions for taxiing, takeoff, landing, and navigating through controlled airspace. Without ATC, you may not be aware of other aircraft in your vicinity, which can lead to potential conflicts or collisions. Additionally, you will not receive critical flight information, such as weather updates or clearance instructions.
