A British Airways Boeing 787 and Qantas Airbus A330 suffered a loss of separation while departing Sydney/Kingsford Smith Airport last year, a report by the Australian Transport Safety Bureau (ATSB) has found.
On the afternoon of September 28, 2022, the 787-9 Dreamliner G-ZBKF (c/n 38622), took off from Runway 16R for a scheduled passenger service to Singapore.
Approximately three minutes later, the A330-200 VH-EBK (c/n 945), departed the same runway for a flight to Cairns in Far North Queensland.
Both widebodies were instructed by air traffic control (ATC) to follow the same standard instrument departure (SID), the DEENA 7, for their respective climbs to 28,000ft.
The SID required the aircraft to meet two separate conditions before a turn to the northwest could be commenced: they had to pass the DEENA waypoint, and had to climb to at least 6,000ft.
