The International Virtual Aviation Organization (IVAO) embodies the excitement and passion of flight simulation fused with the adventure of online Air Traffic Control. IVAO is truly ‘where the virtual world meets the real world…’

Many thousands of pilots enjoy this completely free community driven global network to fly to hundreds of airports daily. A unique combination of voice servers, real world weather servers and aviation databases provides an unparalleled experience for the online aviation enthusiast.

IVAO is established in over 50 countries with a rapidly growing membership in excess of 150,000. Our members not only provide real time Air Traffic Control for our pilots but also enjoy a host of regional and international events including IFR, VFR and military operations. Our famous world tours bring together the delights and challenges of aviation from across the globe and our ‘Crowded Skies’ event lights up the airways with thousands of pilots simultaneously online.

With free training, dedicated integrated software, virtual airlines and a huge global community; whether you are a keen ATC beginner or seasoned commercial pilot, IVAO provides the most realistic online aviation environment available.

The Virtual Air Traffic Simulation Network (VATSIM) is a free network that connects people from around the world flying online or acting as virtual air traffic controllers. The network has a large presence of pilots and air traffic controllers based in the United States and the rest of North America.

Users connect to VATSIM using proprietary pilot software. The software supports multiple platforms, including Microsoft FSX, FS2004, FS2002, X-Plane and Prepar3D. Air traffic control software is provided free, as is training for those who wish to become air traffic controllers.

VATSIM members have access to join hundreds of other pilots in virtual skies and fly around the world. In addition, VATSIM members can join many communities across the world to enhance flying skills and the flight simulator experience in a shared virtual airspace.

VATSIM was founded in July 2001 by a group of individuals who came together with the idea of creating an online community which truly met the needs of flight simulator enthusiasts across the world. As well as providing a common network for flight simulation enthusiasts to connect to, VATSIM aimed to create a global community for learning, sharing experiences, and pursuing new opportunities in the virtual world.

PilotEdge is a subscription-based, payware service that provides professional air traffic control for Microsoft FSX, FS2004, X-Plane, and Prepar3D. There are several subscription options including hourly, monthly, and annual service levels. While there are many free alternatives to PilotEdge, the features below are unique to this payware community.

ATC on a Schedule
PilotEdge provides high-quality ATC 15 hours a day (8am to 11pm PT) and is one of the only communities that offers guaranteed ATC coverage. Pilots pay to use the system, and the controllers are paid to be there, allowing PilotEdge to offer the same schedule for 363 days a year. PilotEdge controllers are rigorously screened prior to working with live traffic on the network. Being a commercial venture with commercial customers that include flight schools, the bar is set very high. Almost any real-world procedure used by civilian pilots can be simulated on PilotEdge.

Unique Radio System
PilotEdge incorporates its own radio system with features not found anywhere else, including:

  • No controller list! No need to see which controllers are online in the area. If it’s within operating hours and you’re within PilotEdge’s coverage area (the Los Angeles ARTCC), simply dial the real-world frequency for the facility you want to reach, and a controller will respond as that role.
  • 100% voice ATC, no text. Many other networks blend text and voice.
  • Voice CTAF. PilotEdge features range-limited voice CTAF, so you can make those position reports at non-towered fields, or chat with other pilots while you’re enroute. The higher you climb, the further you can hear.
  • Full coverage, all the way down to Clearance Delivery at every towered airport within the coverage area.
  • Half-duplex simulation.
  • Recording of all ATC interactions as time-compressed files with silence removed, available for download from the PilotEdge site.

Additional Recorded Traffic
PilotEdge features a library of more than 300 hand-recorded flights in Class E and Class G airspace where communication with ATC is not required. So, get ready for more traffic calls from ATC, even if there aren’t any “live” aircraft around you at the time. From helicopters touring Catalina Island to high speed, low-level military operations, there sure is a lot of traffic out there. There’s even a slope-soaring glider out of the Warner Springs Glider Port.
