# What is VATSIM

> Learn what VATSIM is, how the virtual air traffic control network works, its history, membership structure, and what to expect as a new pilot

VATSIM stands for **Virtual Air Traffic Simulation Network**. It is a free, nonprofit online platform that connects flight simulator enthusiasts with live, volunteer air traffic controllers in real time. When you fly on VATSIM, you communicate with real people providing ATC services - just like pilots do in the real world.

<Tip>
  VATSIM is completely free to join and use. There are no subscription fees, no hidden costs, and no premium tiers. All you need is a flight simulator, a pilot client, and a free VATSIM account.

## A Brief History

VATSIM was founded in 2001 by Harvey Stein as an alternative to the existing online flying networks at the time. The goal was to create a realistic, community-driven environment where virtual pilots and controllers could interact using procedures modeled after real-world aviation.

Since its founding, VATSIM has grown into the largest virtual ATC network in the world, with over **140,000 registered members** across every continent. On any given evening, you can find hundreds of controllers staffing positions and thousands of pilots in the air.

## How It Works

The concept is straightforward. Pilots use a **pilot client** (such as <Tooltip tip="The standard VATSIM client for Microsoft Flight Simulator">vPilot</Tooltip>, <Tooltip tip="VATSIM client for X-Plane 11 and X-Plane 12">xPilot</Tooltip>, or <Tooltip tip="Multi-simulator VATSIM client supporting MSFS, X-Plane, P3D, and FSX">Swift</Tooltip>) to connect their flight simulator to the VATSIM network. Once connected, your aircraft appears on the network and is visible to controllers and other pilots. Volunteer controllers log in using ATC clients and provide services ranging from ground taxi clearances to full oceanic separation.

You fly your simulator as you normally would, but instead of interacting with AI or flying in silence, you talk to real controllers on voice frequencies and share the skies with other real pilots.

## VATSIM vs Offline Flying

| Feature             | Offline Flying          | Flying on VATSIM                                 |
| ------------------- | ----------------------- | ------------------------------------------------ |
| Air traffic control | AI or none              | Real human volunteers providing live ATC         |
| Other aircraft      | AI traffic or none      | Real pilots flying in real time                  |
| Communication       | None or simulated       | Voice and text with real controllers and pilots  |
| Flight plans        | Optional                | Expected for IFR flights, used by ATC            |
| Realism             | Varies by setup         | Closely mirrors real-world procedures            |
| Cost                | Included with simulator | Free                                             |
| Requirements        | Flight simulator only   | Flight simulator + pilot client + VATSIM account |
| Availability        | Always available        | ATC coverage varies by time and region           |

## Network Structure

VATSIM is organized into a hierarchy of **regions** and **divisions**, each responsible for managing ATC services and training in their geographic area.

### Regions

* **Americas (VATAM)** - North America, Central America, South America, and the Caribbean
* **Europe, Middle East, and Africa (VATEMEA)** - Europe, the Middle East, and Africa
* **Asia Pacific (VATAPAC)** - Asia, Australia, and the Pacific Islands

### Divisions

Each region is subdivided into divisions that correspond roughly to real-world countries or groups of countries. For Canadian operations, the relevant division is **VATCAN** (VATSIM Canada), which oversees ATC services and training within Canadian airspace.

Other notable divisions include VATUSA (United States), VATSIM UK, VACC Germany, and many more. Each division has its own website, training programs, and controller roster.

## What You Need to Get Started

To fly on VATSIM, you need three things:

1. **A flight simulator** - Microsoft Flight Simulator (MSFS 2020 or 2024) or X-Plane (11 or 12) are the most commonly used platforms
2. **A pilot client** - Software that connects your simulator to the VATSIM network (vPilot, xPilot, or Swift)
3. **A VATSIM account** - A free account that gives you a permanent CID (VATSIM ID number) and allows you to connect

You will also need a microphone and headset for voice communication, although text-based communication is available as a fallback.
