From BEA's Interim #2:
Quote:
-40 °C is the commonly accepted value below which no more supercooled water exists and thus the risk of ice accretion on the aircraft airframe.
A number of recent posts fail to appreciate the difference between the icing conditions that produce ice accretions on (unprotected) parts of the airframe and the conditions that are suspected to cause blockage of heated pitots.
Yes, I failed to understand this assertion by BEA. Is it possible to have conditions that on the one hand overcome pitot heat to clog them up, but OTOH, don't accrete ice anywhere else? I'm not questioning BEA's assertion. This is an honest question.
