Hi,
let me chime in here with a personal note, hoping it's not offending
anybody.
Hi Torsten, and thanks for your detailed message. Let me explain below why
realistic radio propagation should be inside Flightgear, and aleviate

I can't comment on the actual code, but from the repeated detailed descriptions
of what it actually does, I think it would be a very great

Thanks Eric,
The JSBSim piston engine model is missing something, probably Mach effect
through the intake valve, so models
I'm not a developer here, I just maintain one of the mirror sites.
I would like to comment here a bit.
Over the years I've seen several folks who contributed lots to the
project leave after disputes over one thing or another.
I'd hate to see this lead to something like that!
I personally

Looking at the code (I think) I can see you are trying calculate the pressure
losses in the injector/throttle valve, airbox and inlet tubes. Using throttle
position and engine speed (was expecting cylinder displacement here also).
Basically your MAP at idle is to low, thus the

So it is kind of modelled like an air pump. Interesting method.

Piston engines are basically air pumps.
We currently calculate power by dividing the mass fuel flow by the
user-entered bsfc multiply by correction factors for mixture

There may be many reasons to reject code, but they roughly fall into two
categories: 1) the idea itself which is coded is not acceptable or 2) the
actual implementation is not acceptable
During the last weeks, someone added the 'Grass' landclass to the 'grass_raw'
materials declaration and the 'Dirt' landclass to the 'dirt_rwy' declaration
in/ Materials/regions/materials.xml.
I would like to undo the changes, or discuss other solutions to fix the
problems caused by them - my
