If the speed gets unreliable, i want to be informed about it when the information is available. No need to backtrack it and second guess it from other indications like disconect of autopilot and autothrust.
Thatīs why i remembered to be technically feasible to have the information even some time (seconds) before System "reconfig".
Iīm not convinced that this system is to the best benefit of pilots in abnormal situations.
I hope the advanced planes designers (A, B or ...Z) invest in this issue.
