Re post # 514
The "relative" part of your comment can only be answered subjectively on the basis that a small ice accretion will last a short time (seconds) and a larger one will last relatively longer, but still in seconds
OK it's seconds then
. Since we are talking about AF447 the time to clear the ice and reestablish valid pitot readings is iimportant.
My feeling is that this time would not be expected to be much different than all the other inflight incidents, in other words seconds
