What is the difference of frozen pitot tubes in freezing conditions and
pitot tubes that freezes up due to heavy turbulence?
in this case frozen (ice) is different than freezes (stopped working due air fluctuations)
Maybe a pitot that stopped working due to air fluctuations may begin to work again. Also, what are the odds that all 3 pitots simultaneously stop due to air fluctuations. Whereas 3 identical pitots would theoretically freeze at the same rate and at the same time in icing conditions such as the super cooled liquid water that FLT447 may have encountered.
The symptoms of a failed pitot would be the same regardless of the reason for the failure. For example ice buildup or air fluctuations.
Just my $.02. What does everyone else think?
