Does an ex-Q400 driver count DC?!
It does stand out fairly well against the black background of the boots. Certainly the kind of ice I've seen on it anyway. You can definitely see it breaking off when the boots were working. The inspection lights work pretty well at night too.
Of course in thick cloud, at night and with the landing lights on there can be quite a bit of light reflecting going on it and that would make it quite hard to see.
Ya.....Q-400, whatever 3407 was.
Your last sentence though is probably what they were dealing with that night.
Thanks--
