In a report issued on Wednesday, the Australian Transport Safety Bureau has determined how an Air Asia X wide-body jet wound up in a city thousands of miles away from its destination.
On March 10, 2015, an Air Asia X Airbus took off from Sydney for a scheduled flight to Kuala Lumpur. However, instead of flying to Malaysia, the Airbus A330-343X landed in Melbourne, 500 miles southwest of Sydney.
According to the ATSB, the Captain of the flight input the wrong coordinates for Sydney Airport into the jet’s flight navigation system.
The error wreaked havoc on the A330’s advanced flight management and guidance systems.
“The longitude was incorrectly entered as 01519.8 east (15° 19.8′ east) instead of 15109.8 east (151° 9.8′ east),” The ATSB wrote in its report. “This resulted in a positional error in excess of 6,835 miles, which adversely affected the aircraft’s navigation systems and some alerting systems.”
Instead of Sydney, the coordinates entered by the Captain placed the flight’s point of origin some where off the coast of Cape Town, South Africa, the report indicated.
Unfortunately, the pilots did not realize they made an error until after the aircraft took off and began to fly in the wrong direction.
“Despite a number of opportunities to identify and correct the error, it was not noticed until after the aircraft became airborne and started tracking in the wrong direction,” investigators wrote.
Even worse, the pilots’ attempts to correct the matter managed further deteriorate the situation.
“Attempts to troubleshoot and rectify the problem resulted in further degradation of the navigation system, as well as to the aircraft’s flight guidance and flight control systems,” the ATSB wrote.
Eventually, the pilots elected to abort the flight and return to Sydney. However, weather prevented the flight from doing so, and the flight crew elected to divert to Melbourne. No injuries have been reported relating to this incident.
According to the report, both members of the flight crew were experienced pilots. The Captain has more than 22,000 hours of flying under his belt while the first officer has 2,200 hours of experience.
