Founded in 1997, FlightGear is developed by a worldwide group of volunteers, brought together by a shared ambition to create the most realistic flight simulator possible that is free to use, modify and distribute. FlightGear is used all over the world by desktop flight simulator enthusiasts, for research in universities and for interactive exhibits in museums.

FlightGear features more than 400 aircraft, a worldwide scenery database, a multi-player environment, detailed sky modelling, a flexible and open aircraft modelling system, varied networking options, multiple display support, a powerful scripting language and an open architecture. Best of all, being open-source, the simulator is owned by the community and everyone is encouraged to contribute.

FlightGear – Fly Free!

Major enhancements in this release

Aircraft Modeling

A Failure Management Framework for FlightGear has been added

The JSBSim flight dynamics model now has support for ground effects like bumpiness, solid-ground detection and adjusting of friction factors. Additionally, bogey type contact points sink in non-solid surfaces, making it no longer possible to ride on water.

YASim now has versioning support. The YASim FDM now checks a version tag in it’s configuration file to allow improvements to the YASim FDM without risking breaking older aircraft.

Additional aircraft have started adopting the Canvas navigation display that was introduced with FlightGear 3.0.

Graphics

Improved rendering of VASI, PAPI, runway and taxiway lights.

Orbital rendering using textures from the NASA Visible Earth project

Additions to the Atmospheric Light Scattering (ALS) rendering include: an experimental framework to render cloud shadows on the ground (requires Advanced Weather) a substantial extension of cloud layer visibility using impostor techniques to 150 km a new agriculture effect allowing to render fields without tiling artifacts a new forest effect to simulate managed forest, varying tree size by patch sparkle and fog effect on runway lights much improved visual appearance of rock faces



Usability

An experimental aircraft package manager allows the download of new aircraft, and changing the current aircraft in-sim.

A new internal web server (aka httpd) based on mongoose httpd has been added. It supports various AJAX requests, a screenshot server, a property tree browser, and a web-based moving map and much more.

The integrated Map dialog now uses an azimuthal equidistant projection, for better representation in polar regions and across the International Date Line.

Windows users are now able to use the scroll wheel in dialog lists

Canvas System

Improvements to Canvas, FlightGear’s scriptable 2D rendering system include

Better performance

MapStructure-based layers can now be customized and styled

Support for mouse button and modifiers

CanvasImage now supports the http:// protocol for dynamically retrieving raster images.

protocol for dynamically retrieving raster images. An experimental Map dialog using Canvas is available under the Equipment menu.

Canvas Layout Engine

Nasal Scripting

A new fully-interactive Nasal GUI console based on Canvas has been added: Interactive Nasal Console

the hard-coded flight path history subsystem which samples aircraft position is now exposed via Nasal.

Documentation

Nasal documentation is now included,

Highlighted new and improved aircraft

Other

A text-to-speech system based on flite+hts_engine has been implemented, which is used for ATIS and other messages.

Improved loading behaviour for AI/MP aircraft
