"Generally the loss of speed data is for a short time only......" That sounds like a negligent statement to commit to print when discussing a discrepant speed upset, mm43. Just short enough to cause upset? If the x-AD is crap enough to be useless, and the pilots disconnect them, never to regain their use, what does it matter? Is the disconnect discretionary? What happens when they leave on their own? May as well ask why ALT LAW does the same, manual only all the way home.
It is unbelievable the words are official. Are you paraphrasing? AF says as much as, "deal with a short loss of ASdata, Captain, if it is too long, it must then be your error."

mm43: I appreciate your response and continued skill in this debate, please don't make anything of my harsh comments, they are not directed at you.
