Hi,
"Two test flights were conducted with crews at Airbus Airbus Air France without being informed.
Anyways .. those test flights are useless
1- Not performed in the same environment of the one of the AF447 encoutered
2- The pilots knows in advance what will happend .. what alarm will sounds .. etc ...
We know already by BEA report that the aircraft performed "as per design"
Only interesting if those test flights were performed by the AF447 pilots (same as a reconstitution on a crime scene)
Unfortunately the pilots are no more there ...
