Can anyone explain me this ?

What smoke is on the tail of the planes when they go to 8000m ?

All planes have smoke on their tail when they reach the altitude of 8000m and then disappear at 12000m

They are particles of crystalized water vapor that condense around the aircraft's exaust at high altitude. Basically man-made clouds.

We call that condensation or vapor trails.

It means you need to flip the cloud making switch to off in your cockpit.

What's that SU-27 skin? haven't seen that around... Look Cool

[Guest IguanaKing]

That's the "con layer", Majesco. In LOMAC, its fixed. IRL, its variable depending on local atmospheric conditions. They are basically man-made clouds. The exhaust from a jet engine basically just provides a few extra condensation nucleii for water vapor in the atmosphere. :)

Thank you all !

 

@sp0nge: that's the Su-27 Disruptive skin from Lockonfiles....

[sp0nge]

uhh, ok!

 

Thanks majesco

Just look into the sky any given day and you will see dozens of Vapor trails from Commercial and military airplanes

Thanks Countrycowfreak, but why does it disappear at 12000m (appear only at altitude of 8-12km) ?

[Toady]

And in real life combat conditions you'd stay well out the con layer as it acts like a great big pointer saying 'Look at me. I'm up here'.

As Iguana stated it is scripted in Lomac between 8000 to 12000m. but in real life it varies depending on athmospheric conditions.
