VATSIM (Virtual Air Traffic Simulation Network) is a non-profit organization operating a dedicated, worldwide, Internet-based flight-simulation network. Users can connect to the network to either fly online as a pilot using flight simulation software, or direct traffic as an air traffic controller (ATC) and participate in what has been described as a close approximation of real-life aviation procedures.

VATSIM is one of the two main providers of flight-simulation networks. Communications between pilots and controllers are carried out using integrated voice-over-IP or in-game text messages. Users require custom software to use the network. Through VATSIM, ordinary people have come together as a network of pilots interacting with air traffic controllers to produce a vast, organic simulation of actual air traffic.

The goal is to keep the simulation as close as possible to real-life aviation procedures, including realistic procedural standards and radio phraseology. This has made VATSIM a training aid to student pilots who lack experience at communication with air traffic control, as well as private and commercial pilots looking to enhance their skills, especially in radio communications.

VATSIM is divided into three regions which are further subdivided into divisions. The divisions themselves are divided into Flight Information Regions (FIRs), Virtual Area Control Centers (vACCs) and Air Route Traffic Control Centers (ARTCCs).

The three regions are:

  • Europe, Middle East and Africa Region (VATEMEA)
  • Asia Pacific Region (VATAPAC)
  • Americas Region (VATAMAS)


With years of preparation, VATSIM People’s Republic of China (VATPRC), a division within VATAPAC became official on July 1, 2010. Our division covers a very large land area in VATAPAC, expanding across nine FIRs (Beijing, Guangzhou, Kunming, Lanzhou, Sanya, Shanghai, Shenyang, Urumqi, Wuhan) along with hundreds of airports at various elevations, from the Himalayan Mountains to the South China Sea, and from Tibet Plateau to metropolis of Shanghai and Beijing. All pilots, whether they are flying a VFR flight over mountainous terrain or a long-haul flight from any of the Chinese city to Europe or America, are provided professional ATC service by the controllers at VATPRC.

Please take your time to navigate around our website, here we have a whole wealth of resources and information for all that you need to operate in VATPRC airspace. Hope to see you in our friendly skies soon!
