I don't know of a list, I usually check the mission descriptions in the DCS server lobby.
Check 104th, DDCS, 1st Fighters, Cold War, for example.
But, there's a big BUT:
For public DCS multiplayer servers it is somewhat problematic to allow access to a co-running LotAtc-server.exe because it would be easy for client pilots to simultaneously run the LotAtc-client and thus cheat.
Therefore, public server providers have come up with rules, restricted access and additional precautions for the use of LotAtc.
Amongst those precautions might be:
- restricting access by LotAtc clients to only pre-registered players
- forcing LotAtc client players to be online and thus reachable & controllable through Teamspeak and/or Discord
- enforcing and supervising that players connected as LotAtc clients are not allowed to connect to the server in DCS at the same time.
Cheating by use of LotAtc can be a problem and is impossible to prevent through in-game settings of DCS and LotAtc alone.
