Virtual air traffic control for VFR in French

AiTC: natural interactions powered by AI

AiTC is a voice-based air traffic control system for VFR flight simulation. It allows natural exchanges with controllers, without menus or pre-written dialogues, directly from the simulator cockpit (Microsoft Flight Simulator© (MSFS) and soon X-Plane®).

It relies on up-to-date official aeronautical data, real weather, and the world state as represented in the simulator.

Once connected, there is nothing left to handle on the software side: the radio and push-to-talk button become the only interface. The pilot speaks, the controller responds, and the interaction evolves naturally according to the flight situation.

Designed for VFR in French

AiTC specializes in VFR flying with its specific phraseology while respecting local instructions

VFR is much less standardized than IFR, requiring specific handling: phraseology is more flexible, often marked by local habits, and airspace organization relies on a wide variety of services and rules.

To reproduce this reality, AiTC integrates the logic specific to VFR airspaces, as well as the published instructions for each airfield in France. Data from VAC charts have been analyzed and integrated so that circuits, reporting points, and local procedures truly influence the exchanges.

The goal is not to simplify VFR, but to reproduce its complexity as experienced in real situations.

Everything goes through the radio

AiTC is designed to be transparent once in the cockpit. The application connects to the server and simulator, then stays in the background. The pilot sets up the push-to-talk button and audio settings, and can then fly without ever returning to the interface.

Once the radio is operational and a frequency is selected, exchanges can begin. Simply speak as in a real situation, introducing yourself and stating your intentions. AiTC automatically adapts to the flight phase, aircraft position, and surrounding context.

Real example of communication with AiTC

AiTC relies on AI technologies similar to those used by conversational agents like GPT. They are used to understand and reproduce voice, but most importantly to reason based on the flight situation, applicable rules, and available data.

This approach allows moving beyond fixed dialogues. While following regulatory phraseology, the conversation remains open: the pilot can ask questions, request help or adjustments, report an unexpected event... It's even possible to make mistakes or contradict the controller, as happens in reality. AiTC does not follow a script; it holds a real conversation.

Pay for what you use

AiTC runs on remote servers because the calculations required for the AI cannot be performed locally on a standard PC. This involves recurring costs, incompatible with a one-time purchase model.

However, we wanted to avoid a recurring subscription model and offer a plan that adapts to the user’s actual usage.

AiTC therefore works with a credit system: users purchase packs usable without time limit, and these credits are only consumed when the application is actually used, depending on the volume of exchanges with virtual controllers.

Developed with users

AiTC is still under development, but we chose to release it early to test it in real-world usage. The goal is to evolve it quickly based on tangible feedback.

This means that some features are still missing or imperfect, and system behavior will continue to evolve. Some patience is needed during this phase, even though the system already provides an unparalleled VFR experience on French airfields.
