Telnet usage

FlightGear comes with an internal command server. This so called “telnet” server provides a “remote shell” (like a command prompt) into the running FlightGear process that can be used to inspect and modify runtime state, but also to run commands. FlightGear can be configured to act like a telnet or even an http “server”.

Howto:Multiplayer

The multiplayer feature of FlightGear makes it possible to see other pilots and vice-versa. This makes it possible to fly in formation, perform mid-air refueling with tankers controlled by real people or contact real air traffic controllers to ask for guidance.

Property Tree/Web Server

It has been suggested that this article or section be merged into Property Tree Servers . Discuss this merge. This has been proposed since September 2020. This feature received significant updates in FlightGear 3.1+: While working on the new radio/atis implementation, Torsten rediscovered the internal httpd (aka webserver) to browse the property tree.
