Rain Ice
Had a couple of encounters.
Out of St Johns Newfoundland at night - not forecast. Ac stopped climbing and started descending (at climb power!) Windscreens completely iced. Guess wing profile completely changed plus weight of ice. All systems on then just sit and wait, 12000ft down to 5000ft!
In Gander, left hotel for airport as it started to rain. We got there, 2nd cab went off the road, 3rd cab couldn't get out up the hotel car park slope!
Route checking a Captain out of Gander. Rain ice forecast in the area. After first encounter decided not to go. Called Lords and Masters at Group. They couldn't understand the danger. Said I would get off and Captain could talk to his own Sqn Auth as he was a D Cat. Group said that would be ok and he could probably be told to go! I said ok but I would tell ATC to hold him while I E Catted him if he tried to go. Group backed down and agreed to a 16 hour delay.
