The idea of this is that it's a simple approximation to a very , very complex problem, but it has real effect on the flying experience.
So my existing atmospheric code will be modified to include the new information this code provides.
So the atmospheric variables used in the simulation will be modified by the local weather conditions. This will then automatically effect things like propeller and engine efficiency, pressure based altimeters, jet engine efficiency, fuel use, damn anywhere pressure and temperature are used in an equation.
Then I can easily use the terrain to modify the velocity of the air, producing updrafts and downdrafts.
So now I have a simple approximation to the atmosphere in three dimensions.
AND it actually effects the pilot experience.Then I can start simulating other more ephemeral effects. Icing, misting, contrails, etc.
As long as there are 36 hours per day and I don't have a life.
