It would be very cool if we were to get dynamic runway contamination, where wet runways adds to your stopping length, you risk hydroplaning etc., and with snow/ice on the runway you will risk skidding off the runway. I believe there are ways of defining “amount of contamination”, and if possible this could also pair well with different types of runway design, with grooves etc.
I agree. This should be added when they are working on the weather system. Dynamic runway conditions are a concern that I think would be a good change if it was added.
