We're talking about different things. The value controlled by the red lever is a volumetric ratio; think about how the carburetor venturi works, and you'll see how this must be. Clearly you already do: > The *carburretor* works on a volume ratio. > [...] > The fuel injectors are set up to mimic the carburretor Bingo. I'm talking about "mixture" in the sense a pilot would use it: the position of the red lever in the cockpit. Clearly there are other definitions. And this, by the way, is exactly what I meant about no one defining mixture properly. You read a textbook and get one answer, a flight instruction manual and get another. :) A pilot who moves the red lever thinking it controls the mass ratio will get it wrong. Likewise, an FDM author who wires the /controls/mixture[0] property to the mass ratio will get wrong behavior. Whether you call that thingy "mixture" of "redness" is kinda academic. > Please lets never again talk about having enough fuel to burn all > the oxygen. Lets talk about having enough oxygen to burn all the > fuel. You say potato, I say potato... Seriously, you can look at the problem both ways. Why doesn't an engine work in a vacuum? Surely you wouldn't argue that it is because there's too much fuel. :) Andy -- Andrew J.
