Overview

The FlightGear development team is proud to announce the release of version 2.4.0 of its free open source flight simulation program. FlightGear 2.4.0 reflects over one and a half years of development and incorporates several new and exciting features, as well as numerous bug fixes.

One of the hallmark features of this new FlightGear version consists of a completely overhauled weather module. While it was previously already possible to load realistic weather by downloading (or creating custom) METAR weather reports, the current FlightGear 2.4.0 version takes weather generation an order of a magnitude further by applying the laws of physics to the reported conditions and by determining how the atmosphere interacts with the terrain. This results not only in customizable weather, but also in all the exciting phenomena that occur at the boundaries between different weather systems. Among the numerous phenomena included in the weather simulation are fog layers that are limited in altitude, cold fronts, thermals, cloud formation in updraft winds along mountain ridges, and many, many more. In FlightGear 2.4.0 checking the weather is no longer a luxury option, it is essential for flight safety.

Adding to the improved visual experience, FlightGear 2.4.0 introduces numerous graphical enhancements. By employing state-of-art computer graphic techniques, FlightGear 2.4.0 is capable of rendering highly realistic mountain surfaces, 3-dimensional cityscapes, or shiny metallic surfaces. Through the application of these new computer graphics, water moves realistically and sunlight is reflected from its surface. Many new aircraft models are so realistic and detailed it is almost possible to see oneself reflected in their hull. If that isn’t enough, FlightGear 2.4.0 can draw a full 3D image, through one of the many stereoscopic rendering options.

FlightGear’s user experience is also enhanced through several improvements to the software. New and extended autopilot controllers have resulted in a dramatic improvement in autopilot stability in many aircraft. Additional cockpit systems such as TCAS, and EICAS systems –as well as other realistic aircraft reactions to the environment– provide unique new challenges and opportunities. And if these systems still can’t prevent one from getting lost, it’s always possible to pull up a moving map, or use the new and improved heads up displays.

Under the surface, FlightGear 2.4.0 also introduces several innovations. A brand new experimental HLA interface layer allows for real time communication between several independently operating modules, either running on a single computer, or on a cluster of networked machines. Eventually, HLA allows for a complete modularization of FlightGear, and its integration with professional high-end flight simulator hard- and software components.

Finally, FlightGear 2.4.0 has a built-in option to keep its scenery up to date and download new scenery areas on the fly. While this was already possible by using an external program, this feature is now incorporated in FlightGear itself. The many new and updated scene models all around the world will keep one busy exploring the world of FlightGear. With a choice of nearly 500 different aircraft, from historical to bleeding edge, from ultra-lights to the ultimate flying heavy metal, there is something to cater to each one’s taste. In FlightGear 2.4.0 it’s no longer the sky that is the limit; it’s the imagination.
