The IVAO ATC Client, known as IVAC, is a stand-alone program specifically developed for IVAO, based on the real radars of Belgocontrol, Eurocontrol and Amsterdam Radar, which allows you to control on the network.

IVAC is a feature-rich application that provides an extensive set of tool for positions ranging from delivery to centre controllers. This free software client allows you to keep in touch and coordinate with our online pilots.

The successor of IVAC 1 is under development, IVAC 1 will only receive maintenance updates.


IVAC2 Testing has now been extended to all registered IVAO members.

As this is an on going development, in order for you to always get the latest version of the software, we kindly ask that you visit the Terminal2 Solutions website.

They have also made available a Documentation Library Here.
