IVAO

IVAO (International Virtual Aviation Organisation) is one of the two major global networks providing a free, realistic online environment for flight simulation enthusiasts. Similar to VATSIM, it connects thousands of virtual pilots flying on platforms like MSFS, X-Plane, and P3D with volunteer virtual Air Traffic Controllers (ATC) in a single shared world.

Their motto is "As Real As It Gets." IVAO focuses on providing a simulated real-world environment where members can learn and practice aviation procedures, communication, and navigation under the guidance of human ATC. The network offers extensive training materials for both pilots and controllers, a structured ranking system, regular events, and specialized group flights (Special Operations). It is an excellent platform for those looking to experience the immersion of flying in a busy, controlled airspace.
