Hello everyone!
One thing that bothers me since MSFS 2020 is the lack of contrails on live traffic/ai traffic/multiplayer aircraft whenever your own aircraft is not flying in contrail conditions.
AIG and FSLTL have proven that it’s possible to change this using behaviors and low fidelity effects to not punish performance too much.
Because of this I’d love to see contrails also from ground level on passive aircraft models.
