First I have no idea why your turning the engine off. The game starts with it on and far as I can tell there is no way to stop the F-94B engine in game WITH OUT changing to another aircraft and stopping its engine than change back to the F-94B. The bug could be from doing this. I can't get the same to happen no mater what. Would need to know what Airport and what runway at that Airport, Time, Date and how you shut the engine off.
The "Foom!" sound was coded to the fx_afterburner effect. I changed the "Foom!" to be controlled by the dsd_xml_sound3.gau. Now if the afterburner is OFF you won't hear the "Foom!" sound if you press L. If the afterburner is on and your press L you still get the "Foom!" sound. If that is a prob just swap the AB_Start No Sound.wav and AB_Start.wav.
NEVER EVER PRESS the "I" or Smoke key.
GUNS DO NOT WORK ON THE GROUND. EVER!
That is how things should be. Sound and flames appear as they should when the throttle is fully open WITH engine running.
Same bug as #2. Fixed as can be.
Again NEVER EVER PRESS the "I" or Smoke key. Use one of the brake keys F11, F12 or "." Not a good idea to use the Parking brake (Ctrl + ".") Just because you have to hit the Parking brake key to start and again to stop the guns.
Having the muzzle flash, but no tracers. I have seen that it takes time for the game to play the tracer effects. The tracers are in same FX as the muzzle flash. I now made a deacated tracer effect. Not sure that this makes things better or not.
Try below and see what you get.
