Thanks for the reply Vilas, makes absolute sense as you describe it - quick question if I may? assuming that the CM2 position has control after the scenario as described (even though not as you would do, obviously) - what would you expect the CM2 position to do ideally? if indications look normal on PFD2, just fly the aircraft (No AP, FD or A/THR, ALT Law) - or would you prefer application of the "Unreliable Airspeed" procedure? I appreciate there is a lot more to consider, this is just in general.
