įlightGear reached 1.0 in 2007, 2.0 in 2010, and there were 9 major releases under 2.x and 3.x labels, with the final one under the previous numbering scheme being "3.4", since "3.6" was cancelled. The project moved to a regular release cadence with 2-4 releases per year since 2016, with the first version under the new naming scheme being "2016.1". Around that time, the graphical front end "FlightGear Launch Control", also known as "FGRun", was replaced by a hard-coded Qt launcher.

Simulator Features Physics įorces experienced by a flying craft depend on the time-varying state of atmospheric fluid flow along the flight path - the atmosphere being a fluid that can exchange energy, exchange moisture or particles, change phase or other state, and exert force with boundaries formed by surfaces. Fluid behaviour is often characterised by eddies (Videos: aircraft, terrain) or vortices on varying scales down to the microscopic, but is harder to observe as the air is clear except for moisture phase changes like condensation trails or clouds. The atmosphere-terrain boundary interaction follows fluid dynamics, just with processes on hugely varying scales and 'weather' is the planetary boundary layer. The aircraft surface interaction works with the same dynamics, but on a limited range of scales. Craft also experience varying gravitational force based on the 3d shape of the potential well and the non-spherical shape of the Earth.Ītmospheric & Environmental Physics įlightGear can simulate the atmosphere ranging from energy inputs/outputs to the system, like energy from the sun or volcanic sources, through to fluid flow on various scales and changes of state.įorces experienced at any point along a flight path, therefore, are the result of complicated atmospheric processes on varying spatial scales, and complex flow along the craft's surface. FlightGear is able to model different surface characteristics such as heating or cooling, and the exchange of heat and moisture with the atmosphere depending on factors like windflow or dew point. FlightGear models the continuously evolving life-cycle of phenomena on various scales, driven by interaction of fluid with terrain. They range from turbulence on different scales to, individual thermals, thunderstorms, through to moving air layers, and depicting air-masses on the scale of thousands of kilometers.
Atmospheric water is modeled by FlightGear ranging from state changes such as condensing into cloud or haze layers, along with energy provided from latent heat to drive convective fluid flow, through to precipitation as rain droplets, snow, or hail.
