Well,I can tell you that we do not wait to fly in this conditions
the system still do not work at this time and we don't know if it is gone be usable this Winter.We don't know how much ice we will get on the horizontal stab and the vertical fin,but we know that if we have ice on it,it is a no go for take-off.The slip ring problem is supposed to be fixed,so will see,but we all anticipate serious problem and some epic flights if it works.
