Compare the best ATC add-ons for MSFS 2020, including BeyondATC, SayIntentions.AI, FSHud, Pilot2ATC and genuinely free alternatives.
BeyondATC is the best paid ATC add-on for most Microsoft Flight Simulator 2020 IFR pilots. SayIntentions.AI is best for conversational VFR/IFR, FSHud for AI-traffic sequencing, and Pilot2ATC for a configurable desktop workflow. There is no genuinely free, full AI ATC replacement; free choices are built-in ATC or human-controller networks such as VATSIM and IVAO.
Best MSFS 2020 ATC add-ons compared
The right MSFS ATC add-on depends on whether you prioritise IFR procedure, free-form speech, control of injected traffic or detailed configuration.
- BeyondATC: our general recommendation for routine IFR airline flying, with convincing phraseology, speech interaction and a relatively approachable workflow.
- SayIntentions.AI: the stronger choice for unscripted VFR and IFR conversations, amended requests and pilots who do not want to memorise a rigid command grammar.
- FSHud: best when coordinating the user's flight with compatible injected AI aircraft matters more than conversational radio work.
- Pilot2ATC: best for simmers who want extensive planning tools, adjustable procedures and local Windows speech recognition in a traditional desktop application.
Our wider comparison of voice-controlled and human ATC options examines how their speech systems differ across flight simulators.
What each MSFS ATC add-on can and cannot do
No MSFS 2020 ATC mod does everything: speech recognition, traffic injection and control of AI aircraft are separate capabilities.
| Option | IFR clearance and approach | VFR and free-form requests | Speech input | AI-aircraft sequencing and traffic source | Cloud or subscription dependence | PC/Xbox | Principal limitation |
|---|---|---|---|---|---|---|---|
| BeyondATC | Strong support for clearances, en-route instructions, arrivals and approaches within its supported procedures | VFR support is more structured and less conversational than SayIntentions.AI | Yes | Can coordinate supported traffic when its documented traffic mode and compatible model library are used; do not run a second injector | Paid application with online and cloud-dependent functions; voice usage terms depend on the selected voice service | Windows PC; no Xbox support | Requires an internet service and careful traffic configuration |
| SayIntentions.AI | Handles IFR clearance, route changes and approach requests conversationally | Strongest option here for VFR, flight following and requests expressed in ordinary language | Yes, free-form speech | Use only its documented traffic features or supported mode; it should not be assumed to control every aircraft from an arbitrary injector | Cloud service with an ongoing subscription model | Windows PC; no Xbox support | Requires a reliable internet connection and can be less deterministic than menu-driven ATC |
| FSHud | Supports structured IFR clearances, departures, arrivals and approaches | Structured VFR support rather than open-ended conversation | Not a free-form natural-language system; interaction depends on the supported mode in the installed release | Its main strength; use a traffic injector or model set explicitly supported by FSHud | Paid desktop application rather than a conversational AI subscription; activation and data functions may require internet access | Windows PC; no Xbox support | Less natural radio interaction, with results dependent on traffic and airport data |
| Pilot2ATC | Mature IFR clearance, procedure and approach handling | Supports VFR plans, flight following and recognised VFR requests | Yes, using grammar-based Windows speech recognition | Can detect simulator traffic but is not a complete controller or sequencer for surrounding AI aircraft; no injector is required for ownship ATC | Paid licence; core recognition is local and does not require a conversational AI subscription | Windows PC; no Xbox support | Older interface, substantial setup and a speech grammar that must be learned |
| Built-in MSFS ATC | Basic IFR clearance and approach handling, with occasional route, altitude and runway errors | Basic menu-driven VFR services; no free-form requests | No pilot speech recognition | Attempts to manage native offline and live traffic, but sequencing can be inconsistent | No separate purchase; online services are needed for live traffic and other connected data | PC and Xbox | Limited phraseology, weak recovery from unusual situations and inconsistent traffic logic |
| VATSIM or IVAO | Human IFR control where a controller is online | Human VFR services where coverage and local procedures permit | Yes, live voice with real people | Controllers manage network pilots, not offline simulator AI; use the network client and disable conflicting offline traffic | Free account and internet connection; no AI subscription | Integrated clients require PC; no equivalent Xbox client | Coverage varies by airport and time, and pilots must follow network rules |
| Free chatter or traffic utilities | No | No | Chatter tools provide audio only | A traffic injector can add aircraft but does not itself provide clearances or ATC sequencing | Depends on the utility | External freeware utilities are generally PC-only | They create ambience or traffic, not an AI ATC replacement |
Best free ATC add-ons for MSFS 2020
There is no genuinely free AI ATC for MSFS 2020 that replaces the built-in controller with full speech, IFR and VFR handling plus reliable AI-traffic sequencing.
Built-in Microsoft Flight Simulator ATC
The built-in ATC is the simplest free choice because it is already included on PC and Xbox. It can issue IFR clearances, vectors, altitude instructions and approach clearances, and it provides basic VFR options through the ATC window.
It is sufficient for casual flying and practising the broad order of an IFR flight. Its weaknesses appear when a route changes, terrain makes an assigned altitude unsuitable, airport data disagree or native traffic disrupts the runway flow.
VATSIM and IVAO human ATC
VATSIM and IVAO provide the best free ATC experience when suitable volunteer controllers are online, but they are human-controller networks rather than AI ATC systems.
You communicate by voice, file a flight plan and share the network with other pilots. Coverage is not guaranteed, and newcomers need to learn the applicable phraseology and network rules. For procedural realism, however, competent human control is preferable to generated ATC.
Our guide to no-cost ATC software and volunteer controller networks explains the setup and coverage trade-offs in more detail.
Freeware traffic and radio utilities
Supported freeware utilities are useful companions, not standalone ATC replacements. A traffic package such as FSLTL can inject aircraft and provide model matching, while a radio-chatter utility can add background transmissions; neither gives your aircraft a contextual clearance or conducts an approach.
This distinction matters when searching for free AI ATC for MSFS 2020. Hearing radio calls, seeing more aircraft or receiving human instructions are three different functions, and only the last one supplies genuine free interactive ATC.
Free ATC versus paid MSFS 2020 ATC alternatives
Free ATC is the better choice when cost matters more than constant coverage, while paid AI systems justify their price by being available for almost every flight.
- Use built-in ATC for casual offline flights, basic clearances and an interface that works without another application.
- Use VATSIM or IVAO when you want real controllers, can accept variable coverage and are prepared to use correct procedures.
- Pay for AI ATC when you want on-demand control at a chosen airport and time, repeatable IFR practice or conversational VFR services without waiting for a volunteer controller.
- Pay for traffic-aware ATC when surrounding AI aircraft must follow the same runway and sequencing logic as your own flight.
A paid voice system is not automatically better than human ATC, and a traffic injector is not automatically included. Check which voices, traffic features and online processing are covered by the licence or subscription before buying.
Which option suits VFR and IFR flying?
Choose BeyondATC for routine IFR, SayIntentions.AI for conversational VFR or mixed flying, FSHud for traffic-heavy operations, and Pilot2ATC for detailed desktop configuration.
- Airline IFR: BeyondATC is the most balanced recommendation. Pilot2ATC is a good alternative if configuration depth matters more than interface simplicity.
- General-aviation VFR: SayIntentions.AI is the stronger paid choice for flight following, pattern work and requests that do not follow an exact script.
- Busy airports with injected AI traffic: FSHud is the clearest fit when compatible traffic sequencing is the main requirement. BeyondATC is also an option when its supported traffic system is configured correctly.
- Real-world procedural practice: VATSIM or IVAO is preferable when staffed, because a human controller can interpret unusual requests and react to other network pilots.
- Occasional offline flying: built-in MSFS ATC is usually sufficient if its limitations do not disrupt the flight.
Do MSFS ATC add-ons control AI traffic?
FSHud and the supported traffic features in BeyondATC are the strongest choices when the ATC system must coordinate surrounding AI aircraft as well as the user's aeroplane.
Traffic injection and traffic control are different jobs. An injector creates flights and aircraft models; an ATC engine assigns runways, spacing and instructions. Pilot2ATC can observe traffic without taking complete control of it, while human networks manage connected pilots rather than offline AI.
A mistake we see constantly is leaving MSFS Live Traffic active beside a separate injector and an ATC application's own traffic system. The result can be duplicate aircraft, opposing runway flows and traffic that never responds to the add-on. Use one supported source and consult our guide to traffic injectors and model libraries before combining products.
Do I need a separate traffic injector?
Only install a separate injector when the ATC developer explicitly lists it as supported or requires it for aircraft models.
For ownship-only ATC, Pilot2ATC does not need an injector. Traffic-focused products may require their own traffic mode, a compatible injector or a model library, so follow that product's documentation rather than assuming MSFS Live Traffic will work.
How should I install an MSFS 2020 ATC add-on?
Install an MSFS 2020 ATC add-on as an external Windows client unless its documentation specifically supplies a Community-folder bridge or connector.
- Install and connect the desktop client. Start Microsoft Flight Simulator and the ATC application in the order specified by the developer. Confirm that the application identifies the active aircraft and airport.
- Allow the simulator data connection. Grant any requested Windows Firewall, private-network, microphone and simulator-connection permissions. Do not block the application's SimConnect or equivalent data link.
- Create one matching flight plan. Import or build the route in the ATC application, then make sure the origin, destination, route and procedures agree with the aircraft's flight-management system. Avoid loading several slightly different plans.
- Select one supported traffic source. Enable the injector, traffic mode or model library named in the product documentation. If only ownship ATC is required, leave unsupported injectors disabled.
- Disable conflicting ATC and traffic. Do not answer the built-in ATC while using its replacement. Turn off
AI Radio Communications (ATC), conflicting co-pilot assistance, extra injectors and duplicate live or offline traffic when instructed by the add-on developer. - Configure the microphone and push-to-talk. Choose the correct Windows input and output devices, set the recognition language, assign a push-to-talk control and check that it does not conflict with an aircraft or simulator binding.
- Run a pre-flight connection test. Before pushback, verify aircraft position, route, frequency or listening state, microphone detection, voice output and traffic connection. Fixing these on stand is much easier than after departure.
Navigation-data differences can still cause unknown fixes, rejected procedures or incorrect runways. The simulator, aircraft, ATC application and add-on airport do not always use the same data cycle or airport layout.
Why is the ATC add-on not responding?
Most response failures are caused by a lost simulator connection, the wrong microphone, push-to-talk focus or an application waiting for the correct radio state.
- If the aircraft is not detected, reconnect the simulator data link and check firewall permissions.
- If speech is not recognised, confirm the selected input device and watch the application's microphone indicator while transmitting.
- If instructions refer to the wrong route, reload the plan after any change made in the cockpit.
- If taxi directions are impossible, suspect a mismatch between scenery and the ATC airport database.
- If AI aircraft ignore instructions, remove unsupported traffic sources and confirm that traffic control, rather than ownship-only ATC, is enabled.
- If voices use the wrong device, select the output explicitly instead of relying on the Windows default, which can change when a headset is connected.
Do MSFS 2020 ATC mods work on Xbox?
No external ATC replacement covered here works as an equivalent native Xbox add-on for Microsoft Flight Simulator 2020.
BeyondATC, SayIntentions.AI, FSHud and Pilot2ATC need Windows desktop software and a simulator data connection. VATSIM and IVAO also require external client applications. Xbox pilots are therefore limited to the simulator's built-in ATC and assistance features for an integrated experience.
Microsoft Flight Simulator 2020 remains a PC and Xbox release and was never released for PlayStation.
Will these ATC add-ons work with Microsoft Flight Simulator 2024?
Yes, the developers' support documentation covers Microsoft Flight Simulator 2024 on PC for the four principal add-ons, but traffic integration and connector requirements must still be checked for the installed release.
| Option | MSFS 2024 scope |
|---|---|
| BeyondATC | Supports MSFS 2020 and MSFS 2024 on Windows PC; use the traffic mode and connector documented for the selected simulator. |
| SayIntentions.AI | Supports both PC simulators through its desktop client and online service. |
| FSHud | Supports MSFS 2024, subject to the compatible application build, traffic source and model configuration. |
| Pilot2ATC | Supports connection to MSFS 2024 on PC; the same route, navigation-data and speech-setup cautions apply. |
| VATSIM and IVAO | Their PC clients support MSFS 2024, but human controller coverage remains variable. |
| Built-in ATC | Included with MSFS 2024 on every platform, without requiring an external client. |
The installation checklist above also applies to MSFS 2024: one route, one controller and one supported traffic source. Do not assume that a connector or injector configured for MSFS 2020 can be copied unchanged.
The console limitation carries over. MSFS 2024 is available on Xbox Series X|S and PlayStation 5/PS5 Pro as well as PC, but these Windows ATC clients are not native Xbox or PlayStation applications.
