Contrails modeling?

[Cmptohocah]

If I understand correctly, contrails are water wapour created from the engine by burning fuel. Now since the fuel flow at cruise speed is much higher (read fuel burn), should't the contrails disappear if the throttles are pulled back? For examle, one is cruising at 10km alt and chops the engine speed to flight idle. The trails should at least be less visible, or not visible at all.

 

Please, let me know if I am wrong.

I have similar thoughts about that matter. Is the ED intends to improve this effect in DCS 2.0 ?

Yes, according to interview with Wags, they already updated the contrails. Pcpilot may/june.

Sounds good to me :)

Contrails are not necesarly coming from the engines. Under certain conditions., it is the wing vortices that will cause water to condense inside the low pressure region in the vortex core, resulting in a contrail

You are right about vortices, they cause but short contrails witch doesn't sustain for a long time - they actually disappear after few seconds (We all have access to Wikipedia ;). What we are talking about here are the contrails from the engines ( and you can clearly see they are coming straight from the engines and stay visible for longer period of time. But as it has been said in previous post ED is going to sort it out in forthcoming DCS 2.0 hopefully :music_whistling:
