Powering aircraft by sustainable aviation fuels is a way to tackle the climate impact of aviation. They reduce contrails by decreasing their ice crystal numbers.
The German Air- & Space-Research Center (DLR), Airbus and Rolls-Royce use a Research Aircraft that follows an A350 to make emission measurements (Märkl etal, 2024).
The Falcon_20 (here Citation) @ FL 350 has to be fully immersed in the contrail, closing into the 40m-off-engine range.
This is difficult enough in RL but even more frustrating in the sim: if you approach, the Airliner often (not always) gets a warning: then it turns away or disappears, only to re-spawn somewhere else.
I was “hunting” on the North-Atlantic-Route where there are plenty of “targets” to retry.
Contrails thanks to “42 simfx”.
Its easier to simulate it with the air-refueling-tool from “Airshow Assistant”- at least the Airbus tanker is right in front of and stays…
All well and good, conspiracy theorists may say, but what about Chemtrails?
