At 200 ft AGL given the caution, I would fly the aircraft in the current configuration. Of course it is all to easy to make these comments now that we have an official report of the accident.
The IAS disagree (not a memory item) check list will direct the crew to airspeed unreliable.
First 4 actions on the "airspeed unreliable" QRH nnc are memory items and include "pitch and power", it is not anywhere suggested to clean up, at a point the checklist says "set pitch and thrust for the current configuration of flight" and warns of possible multiple warnings.
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.
