Free and Open Source Flightgear flight simulator has issued an update
FlightGear is an open-source flight simulator. It supports a variety of popular platforms (Windows, Mac, Linux, etc.) and is developed by skilled volunteers from around the world. Source code for the entire project is available and licensed under the GNU General Public License.
It's worth noting some of the advanced features that this free flight simulator offers (I remember using those cheap coloured glasses a few years back with this sim to see a 3D view in the cockpit):
With FlightGear it is possible to choose between three primary Flight Dynamics Models. It is possible to add new dynamics models or even interface to external “proprietary” flight dynamics models: JSBSim, YASim and UIUC.
Over 20,000 real world airports included in the full scenery set. Correct runway markings and placement, correct runway and approach lighting. Taxiways available for many larger airports (even including the green center line lights when appropriate.). Sloping runways (runways change elevation like they usually do in real life.). Directional airport lighting that smoothly changes intensity as your relative view direction changes. World scenery fits on 3 DVD’s. Accurate terrain worldwide, based on the most recently released SRTM terrain data.) 3 arc second resolution (about 90m post spacing) for North and South America, Europe, Asia, Africa, and Australia. Scenery includes all vmap0 lakes, rivers, roads, railroads, cities, towns, land cover, etc. Nice scenery night lighting with ground lighting concentrated in urban areas (based on real maps) and headlights visible on major highways. This allows for realistic night VFR flying with the ability to spot towns and cities and follow roads. Scenery tiles are paged (loaded/unloaded) in a separate thread to minimize the frame rate hit when you need to load new areas.
TerraSync is a utility that automatically downloads the newest version of the needed FlightGear scenery while the simulator is running. TerraSync runs in the background (optionally as a separate process), monitors your position, and downloads (or updates) the latest scenery from the master scenery server "just in time". For some time now TerraSync has been integrated into the core FlightGear process, so there is no need to deal with TerraSync for the typical user.
FlightGear implements extremely accurate time of day modeling with correctly placed sun, moon, stars, and planets for the specified time and date. FlightGear can track the current computer clock time in order to correctly place the sun, moon, stars, etc. in their current and proper place relative to the earth. If it’s dawn in Sydney right now, it’s dawn in the sim right now when you locate yourself in virtual Sydney. The sun, moon, stars, and planets all follow their correct courses through the sky.
FlightGear has the ability to model a wide variety of aircraft. Currently you can fly the 1903 Wright Flyer, strange flapping wing “ornithopters”, a 747 and A320, various military jets, and several light singles. FlightGear has the ability to model those aircraft and just about everything in between.
FlightGear has the infrastructure to allow aircraft designers to build fully animated, fully operational, fully interactive 3d cockpits (which even update and display correctly from external chase plane views.)
A number of networking options allow FlightGear to communicate with other instances of FlightGear, GPS receivers, external flight dynamics modules, external autopilot or control modules, as well as other software such as the Open Glass Cockpit project and the Atlas mapping utility.
A multi player protocol is available for using FlightGear on a local network in a multi aircraft environment, for example to practice formation flight or for tower simulation purposes.
The powerful network options make it possible to synchronize several instances of FlightGear allowing for a multi-display, or even a cave environment. If all instances are running at the same frame rate consistently, it is possible to get extremely good and tight synchronization between displays.
