>> well yes, i think we've always said it seemed to be a weather-related issue, and i'm quite sure it is a bit of icing, especially of the airspeed indicator, which is called a pitot tube. there's a french incident a while back and the authorities actually put it down to that. in fact there is a directive out that was issued last october asking that a different form of this tube a morrow bust version should be installed. so not too sure whether or not this particular aircraft did have the updated pitot tube. this might be one of the problems. of course if this is sending incorrect information, like all computer systems, rubbish in rubbish out. so it's sending incorrect commands which although there is software on board which will try to correct the incorrect commands but who knows.
