Engine flameout when parked with tail wind

[Proper Charlie]

Could possibly be correct behaviour, but the Mirage F1 is the only plane I've seen it in.

If you are stationary on the ground with a sizeable tail wind, the engine flames out.

In the attached track there is a ~ 40 knot tail wind (DCS should have changed the active runway to the other direction, but that's a separate issue) - the engine almost immediately flames out.

Hi @Proper Charlie,

It's not a bug, with an excessive tail wind, the engine RPMs have to be kept high (above 7000-7500) to avoid the engine shutting down. Same if you're performing a hammerhead.

Hi again, after discussing with SMEs, the effect should be tweaked so the density of the air plays a role in it. So when it's corrected, it won't probably happen on the ground anymore.

It's a real behavior of jet engines. In the AF when we are going to ground run sometimes we have to tow them to point them into the wind.

Hi, @FlankerKiller, isn't that more in the case of engine start than when the engine is already started?

[FlankerKiller]

No, a wind gust can cause a compressor stall at any time. What's really dangerous is a sideways wind. It can starve the engine of air and let all that combustion come forward. It'll wake your ass up when you've been running ground for like two hours. Newer engines have better ways to deal with it so don't stall as much. But older engines need constant smooth air down the intake.

How high of a wind speed are we talking here? DCS engine doesn't allow us to set orientation of aircraft started on the ramp.
