LSD
Go to ADDS web site there is prediction for LSD..if you do icing training and this is from NASA it s available on AOPA and FAA/ FAST TEAM / you we ll read about it..Second have you seen documentary on NOVA about AF 447 ? if not watch it on netflix under crash of flight 447..this investigators had very good idea what happened..even they mentioned something that the Franch did not and that is..Several crews responded only with pitch change and they were up to 60 sec late reacting with power by that time they put AC into stall when pitot failed.
As far as LSD i stand by that cause it s part of the training /FAA/
