How do I fix ATC bugs in MSFS 2020?

To fix ATC bugs in Microsoft Flight Simulator 2020, first identify whether the fault is audio, radio tuning, flight-plan logic or an add-on conflict. Check COM1 and the audio panel, disable AI radio assistance, reload the flight plan, test with an empty Community folder, then restart the flight if ATC remains stuck.

Fix ATC bugs in this order

The fastest method is to separate radio and audio faults from flight-planning errors before resetting anything.

1. Take manual control of the radio. Turn off AI Radio Communications during diagnosis. Otherwise, the copilot can retune COM1 or answer before you do, making an apparently random ATC fault difficult to trace.
2. Check the complete radio path. Confirm electrical and avionics power, place the required frequency in the active rather than standby field, and select COM1 or VHF1 for reception on the audio panel. A displayed frequency does not mean that its receiver is being monitored.
3. Give built-in ATC a simulator flight plan. Create or import the route through the World Map and select IFR when appropriate. A route entered only into an add-on aircraft's FMS may not be visible to MSFS 2020 ATC, so clearance and hand-off options can be missing.
4. Test ATC voices separately. If menu text and responses work, the radio connection is probably fine. Check the Voices volume and ATC text-to-speech setting. On PC, switch from Azure to Windows Offline where available; cloud voices also require Online Functionality and a working connection.
5. Run a controlled test. Use a default aircraft at a stock controlled airport with a simple World Map flight plan. If that works, the core ATC system is functioning and the original aircraft, airport or route is the likely cause.
6. Isolate installed content. On PC, move the contents of the Community folder to a temporary location and test again. If you do not know which packages folder MSFS uses, the InstalledPackagesPath entry in UserCfg.opt identifies it. On Xbox, remove the suspect package through Content Manager.
7. Restart the flight session. ATC state is tied closely to the active flight, and some stuck clearances or hand-offs cannot be rebuilt in place. Exit to the main menu and reload; if that fails, close MSFS completely. On Xbox, quit the application instead of resuming it through Quick Resume.

If you are unsure which step in the normal clearance sequence was missed, compare the flight against our explanation of the built-in ATC workflow, frequency changes and hand-offs.

Why is ATC silent even though the menu works?

Silent ATC with visible text is normally a voice-output problem rather than a radio-tuning problem. Check the voice and overall sound levels, confirm that text-to-speech is not disabled, and change from the online voice option to an available offline voice for testing.

If text, response choices and controller contact are all missing, inspect aircraft power, COM1 tuning and audio-panel selection instead. Our full checklist for silent controllers, missing menus and radio faults covers each symptom separately.

An interruption to cloud-generated voices cannot be repaired by reinstalling the simulator. Continue with ATC text or use the offline voice option until the online service is available again.

Why does ATC give the wrong vectors or runway?

Wrong ATC instructions usually come from a weather or flight-plan mismatch, conflicting airport data, or a limitation in the built-in controller logic. They are not usually fixed by changing the voice or radio settings.

• Select the expected departure, arrival and approach after checking the weather used by the flight.
• Make sure the World Map route and aircraft FMS contain the same waypoints and runway.
• Remove older or duplicate scenery for the affected airport. Taxi instructions use the airport's ground network, which may disagree with another scenery package.
• Expect occasional late descents, unsuitable vectors or runway changes from built-in ATC. If an instruction is unsafe or conflicts with terrain and the published procedure, disregard it and fly the safe procedure.

For persistent route-specific problems, use our checks for diagnosing incorrect vectors, runway choices and taxi routes.

Can you reset ATC without restarting the flight?

A stuck ATC panel can sometimes be recovered in flight, but MSFS 2020 has no guaranteed full ATC reset button.

1. Disable AI Radio Communications so it stops changing frequencies.
2. Close and reopen the ATC toolbar panel.
3. Verify the active COM radio, then swap and retune the standby frequency.
4. Use the available contact or hand-off option again after tuning the correct controller.
5. If the menu remains blank or repeats an old clearance, return to the main menu and reload the flight.

Saving before a restart may preserve a basic flight, but complex add-on aircraft do not always restore their complete FMS and cockpit state correctly.

Can aircraft and scenery add-ons break ATC?

Aircraft, airport and ATC add-ons can break communication by changing radio behaviour, withholding the FMS route from the simulator, replacing airport frequencies or competing for control of COM1.

With an add-on airliner, check its own VHF1 controls and audio panel before blaming the simulator. FlyByWire users can follow our aircraft-specific A32NX radio and ATC checks.

Run only one source of ATC instructions at a time. If a third-party controller is managing radios or the flight plan, disable built-in AI radio assistance and any other tool trying to perform the same task. Also install available simulator, aircraft and scenery package updates before retesting.

Do not reinstall MSFS first. Reinstallation rarely fixes a muted voice channel, mismatched flight plan or aircraft-specific radio configuration. Clearing the rolling cache does not reset an ATC session either; reserve that step for scenery or streamed-data problems.
