To: 320 Driver
I am a Reliability engineer and not a pilot so I really do not understand what you said. I don’t disagree with it I just don’t understand. I was given this information while up-front on an Air Canada A-320. I was discussing with the pilots about uncommanded operation of the flaps and slats on the A-310 and the possibility of it occurring on the A-320. Since the system architecture is the same on Airbus aircraft and the same manufacturers were involved in supplying the mechanics of the flap slat drive system the possibility of occurrence was there. After I offered that information to the pilots the co-pilot who was a four stiper and also served as the Air Canada safety pilot dug into a pile of faxes and pulled one out and showed it to me. The fax described the uncommanded operation of the flaps on an A-320 that had happened several days prior to that time. Most likely the reasons offered by you in the above post had not been determined when the fax was sent. But if the architecture is the same, there is a possibility of uncommanded operation that the computer could not stop. This is true on the A-310 and it could happen on any Airbus aircraft.
