Extracts from FCTM:.. The current flap position should be maintained until the memory pitch and thrust setting have been set and the airplane stabilized. If further flap extension/retraction is required refer to PI-QRH Airspeed unreliable table.
​​​​​​. Settings are provided for flight with and without flaps extended. The crew should use the setting for the condition they are in to keep the airplane safe while assessing the checklist etc...
Toghether with ET flight, it is the third fatal accident involving "unreliable airspeed" in recent times including a FBW aircraft.

Agree with your comments and quotes from the FCTM.
My response was to another poster who had asked what actions would to do if IAS disagree caution appeared at 200 feet AGL. Fly the aircraft then assess, plan and act accordingly.
