Certainly that's what I've always understood.
I have often noted that many pilots do not understand (or have forgotten) that 'slippery when wet' means that 'ice' values must be used for performance planning when that runway is anything other than damp (surface colour change, no glistening).
At Lulsgate, it has been seen that 10 airlines have quite rightly taken a stance against the risks posed by a 'slippery when wet' runway - and yet others, some of whom who operate the same aircraft type, have continued. Why are some airlines prepared to risk their passengers' safety when others are not?
