LotAtc is a client + server software witch is connected with DCS World Simulator and provide users to get an ATC/CGI view of the battle.

Play the role of a tactical or air traffic controller and provide help to human pilots so that they better accomplish their missions, by radioing them a picture or guidance instructions!

LotAtc 4 DCS is for DCS multiplayer (but works well in solo also!); as an ATC, you may radio your instructions & informations to pilots using a voice software such as TeamSpeak, Mumble… etc.

LotAtc originally stands for “Lock-On tiny ATC” (back in 2006!) and later “Lock-On tactical Air Traffic Control” to emphasize the importance of the tactical part.

The original name was retained for the current LotAtc 4 DCS version as it is well known by the online community.
