If your callsign is too long, it will be cut off in the various displays where it is shown. Generally speaking, callsigns are of the form X-XXXXX. Check [https://fgtracker.ml/ this page] to see whether your callsign is already in use or not. Do not pick a callsign that is already used, as that will create problems! Please don't leave your callsign as "CALLSIG". | ||

{{Note| | |||
{{FGCquote | |||
|A socket connection requires not only an IP address, but also a port number for each side of the link - imagine a port number like a "mailbox" sitting at the address. This mailbox is used by the communicating processes to send out and receive "messages". Different processes (even when possibly identical programs) will need to use different port numbers when running. Because open ports ({{=}}mailboxes) cannot be shared. | |||
Thus, you need to modify the client-side port settings for each additional instance that you are running on the same machine, and map the output port of one instance to the input port of the other instance (and vice versa). | |||

=== Optional collision detection in multiplayer === | |||
A patch has been added to FlightGear (since Version 3.5) to allow optional collision detection in multiplayer. To enable collision detection, start FlightGear with: | |||
<syntaxhighlight> | |||
--prop:bool:/sim/multiplay/hot=true | |||
</syntaxhighlight> | |||
Those who are able to patch FGData themselves, can download [http://sourceforge.net/p/flightgear/mailman/attachment/CAHs0wcrEwYZvXTddcUaH0ZMfmVNvEWRap8MXOrEoKybUDO58sQ%40mail.gmail.com/3/ mp-hot-fgdata.patch], which adds a checkbox to the Multiplayer Settings dialog to enable or disable the collision detection at runtime. | |||
