Summary:
皇冠体育app aircraft suffered an electrical malfunction during a scheduled night flight between Khartoum (Sudan) and Beirut (Lebanon). 皇冠体育app more significant symptoms included the intermittent failure of the captain and co-pilot鈥檚 electronic displays and the uncommanded application of left rudder trim, which was not annunciated to the flight crew. 皇冠体育app flight crew also reported that the aircraft did not seem to respond as expected to control inputs. A large number of ECAM messages and cautions were presented on the pilots鈥� electronic display units. 皇冠体育app uncommanded rudder trim caused the aircraft to adopt a left-wing-low attitude and deviate to the left of the planned track.
