FMAI Tornado Smoke Effects

Does anybody have the entries for the aircraft.cfg file?

While following a FMAI Tornado I remembered one thing I have seen in real life many times: After the afterburner/reheat is switched off the aircraft usually left a yellow cloud (can be seen best in humid weather). I was told this is due to the fuel that is pushed out of the fuel pipes (about two gallons per engine) when the afterburner is disengaged. Does anybody know of a visual effect like this for the Tornado?

The best vid I could find is here:

Start at about 45seconds. Also at 4:19.

The same "cloud" is visible upon afterburner ignition.

Thanks in advance.

The yellow cloud is I think brown. This is Nitrogen Oxide produced by the afterburner. As the afterburner runs much hotter than the engine the Nitrogen and Oxygen in the air in the afterburner actually combine to produce Nitrogen Oxide or Nitrogen Dioxide, I cannot remember which.

All engines do this when the afterburner is on. Concorde was the same.

Thanks for that information Graham.

But does anybody have the regular smoke entries in the aircraft.cfg file? Or do you all have this AI aircraft flying without smoke fx?

I don't have any smoke effects on mine. The main reason is purely that for AI aircraft you can either have the effect on or off, so the smoke is off.

The only way that you could do what you wanted for the AI Tornado would be to amend a burner effect to add a smoke effect at the end. The trouble is that you would only get the effect once per flight.
