[Flightgear-devel] Turbulence should affect YaSim and JSBSim the same way

Hi, I have been looking over the FG code for sometime and would like to start contributing to the project. I just browsed through the open items and figured out "Turbulence should affect YaSim and JSBSim the same way" issue in 3.0 backlog. As the first step, I am trying grasp YaSim and JSBSim appro

[Flightgear-devel] Turbulence in YASim vs. JSBSim

2011-07-11 Thread thorsten . i . renk
I've recently tested the DG-101G which is (I think) the first JSBSim glider I've been flying in Flightgear. I've noticed a rather strange issue: In Local Weather, I added some amount of turbulence around a thermal proportional to the strength to simulate the fact that a thermal is not a laminar ri

[Flightgear-devel] Turbulence

2010-12-17 Thread thorsten . i . renk
Does anyone understand how turbulence is modelled? I've had the following experience: I've been soaring using the ASK-13 in a test of the new convective cloud life cycle implementation (nothing is as frustrating as a nice Cumulus dissolving just as you are about to reach it...), and by a bug which
