On 20 March 2010, an Airbus A320-232 aircraft, registered VH-JQX, was conducting a scheduled passenger flight from Brisbane to Mackay, Queensland. On decent into Mackay, the crew received multiple Electronic Centralized Aircraft Monitoring (ECAM) messages.
At the same time, the autopilot and engine autothrust disengaged and the primary flight displays (PFD) lost airspeed, altitude and descent data. After about two minutes, all data returned to the primary flight displays. Engine autothrust and the autopilot were re-engaged and the aircraft continued without further incident to land at Mackay.
Recorded data from the event enabled a number of precautionary actions to be completed by the operator with no faults found.
