Howto:Get the standard atmosphere
Sometimes you want to get the standard atmosphere for example when testing a flight dynamics model (FDM).
Why using the standard atmosphere?
When comparing performance of FlightGear aircraft against published performance of real world counterparts it is of course helpful to do that against the same conditions (real world performance numbers are reduced, mathematically corrected, to the performance in a standard atmosphere).
How to get it
- Start up FlightGear
- Open up the property browser (e.g. via --prop:browser=environment)
--prop:/environment/config/enabled=0 --prop:/environment/atmosphere/temperature-deg-sea-level=15 --prop:/environment/atmosphere/pressure-inhg-sea-level=29.92126 --prop:/environment/atmosphere/wind-speed-kt=0
- Turning off turbulence Topic on the official forum.
