Condensation trails of high flying planes not visible if you are below 30.000 feet

[Shazam718660]

So, let’s start with a clarification: I’m not speaking of the condensation trails CREATION here.

OK.

There’s a liner, flying at 38.000 feet. With condensation trails, of course.

On my system, if I’m on the ground or if I’m flying at 20.000 feet, I can’t see the condensation trails of said liner.

If I go with my MB339 over 30.000 feet, I can see the liner trails. If I descend again to 20.000 feet, the liner trails disappear.

Anyone experiencing this, and/or knowing how to solve the issue?

All AI aircraft contrails are only produced when your user aircraft produces contrails. As soon as you descend below an altitude where your aircraft no longer produces a contrail, all AI aircraft stop producing their contrails.

There are some exceptions to this. If you are using FSLTL AI aircraft, some of the models have a contrail effect added to the model and their contrails can be seen from the ground or when you user aircraft is not producing a contrail.

All contrails synched to user aircraft

Realistically, in a standard atmosphere contrails begin to for above about 32,000 ft and this will vary depending on SAT and humidity; however, if you see contrails at 20,000 it’s almost certainly not realistic.

I think this is not the point. He ment, if an aircraft is producing a contrail it can’t be seen from the ground. But it should be visble.
I made the same expirience, just slightly different:
I was flying the TBM and contrails of other planes started popping in only when I myself reached about 10000ft … so below 10000ft no contrails, over 10000ft contrails … this is very wiered indeed.

My original post about it: Con trails are only showing starting from a certain hight

Not seeing contrails of high flying aircraft is annoying, but the emersion breaking flaw is flying above 32000 ft and when looking down, seeing contrails coming from aircraft that are on short final to an airport.

Implying they have a pretty dumb system of deciding whether a contrail is generated, seemingly comparing altitude difference.

I wonder if it disappears as you go higher, then reappears as you descend, matching the OP observation in reverse.
