Pitot tube icing AF447
How long were the pitot tubes on AF447 affected by icing? I have googled and googled and have not found a source for that answer. I am trying to confirm my recollection of the #1 pitot being iced over for just 23 seconds, the #2 Pitot for 54 seconds and the standby being affected for just 1 minute and 53 seconds. I do not recall the source document of my memory. Please help!
