Are their plans to include any kind of Deice or Anti-ice ground service? As it is, there is no way to prevent ice build up. There could be a full deice/anti-ice option for departing in the winter, and just an anti-ice service for when there are icing conditions aloft.
Perhaps there could be a designated deice pad like in real life, but even just having it as a service at the gate would be better than having to fly with dangerous levels of ice buildup. I’m sure it is tougher to do than it seems, but this is a part of flight operations that is very important and you already have the tough part done in terms of actual icing in the sim.
