According to the team, in simplistic terms, the feature will create a dynamic performance model based on icing contamination and buildup resulting from atmospheric conditions. Visually, you can actually see the buildup on the airplane and must utilize the integrated de-ice module to clear contaminated surfaces, both on the ground and in-flight. Moreover, the ground based de-ice process will actually protect against further deposits as in the real world. The icing feature was developed in consultation with real world pilots flying the actual Airbus type.
Certainly groundbreaking work, this sets the bar to a much higher level in my opinion. Check out some images below showcasing the new feature, looks absolutely fantastic!
As the description by the developer is quite extensive and beyond what can be summarized here, head over to the source post at the Flight Sim Labs forum to read the entire explanation. Definitely an exciting step forward!
