Contaminated runways Norway
A few years back, Norway started to sometimes to give runway contamination in quite a special way :
"Runway covered with XX % XXXX (contamination), ON ICE"
e.g. "Runway covered with > 50 % slush, 3mm, on ice"
The special thing is the "on ice"
Normally when you saw the runway, there were no ice to see, maybe a few % on the edges.
This is probably a "cover my ass" procedure from AVIANOR, but it present quite a problem for operators, as you are normally not allowed to operate on ice.
How do you deal with it ?
