No contrails are seen in certain weather conditions

[PhantomP]

I have noticed for a while now that no contrails are seen, when you select in the weather type, bulilding storms. Is there areason for this, such, as realism, or a glitch ,also is there a way to get around this in the fs9config, or is there some kind of tweak possibly. Thanks

Check temperatures at altitude. Also each aircraft can set its own in the aircraft.cfg in the GeneralEngineData section:

max_contrail_temperature=-39.0 //stated in Celsius

The SDK says this:

max_contrail_temperature=-39.0 Ambient temperature, in Celsius, in which engine vapor contrails will turn on. The default value is about -39 degrees Celsius for turbine engines. For piston engines, the contrail effect is turned off unless a temperature value is set here.

Thanks Milton.

Yep - I like to add the line to my high altitude piston pushers like the Connies and Lightnings.

I add it to the ones I fly a lot. Although I usually set the temp to about -25C as I like seeing contrails.

Thanks Willy. I like seeing contrails also on most of my planes.

Thanks to you also Tom Clayton.
