Seven-hour flight to nowhere after British Airways A380 turns back to Joburg

Passengers aboard British Airways flight BA54 endured a seven-hour flight to nowhere after the London-bound Airbus A380 returned to Johannesburg when its weather-radar system failed mid-route.

Delayed start, long detour

Flight BA54 was due to leave O.R. Tambo International Airport at 21:15 on Friday, 7 August, but ground delays of more than five hours meant the aircraft did not depart until 02:36 on Saturday. The A380, registered G-XLEJ, climbed to 34,000 feet and headed north towards London Heathrow.

Weather radar fault over Central Africa

The aircraft spent more than two hours flying over Botswana and Zambia before reaching the Democratic Republic of Congo, where the crew detected a malfunction with the plane’s weather-radar system. The airline’s ground team in Johannesburg noted the radar briefly displayed a warning message after takeoff that cleared, but the report said the “dense clutter” on the radar scope never dissipated, making it ineffective for detecting rain, ice or storm fronts.

An ACARS message indicated the crew attempted to use the backup radar, but it was inoperative. As aviation commentator Luke Diaz explained in reporting cited by the airline update:

“Malfunctioning weather radar might sound minor compared to an engine failure, but in long-haul aviation, it is considered a critical no-go scenario.”

Fuel dump and wait to land

With the aircraft too heavy to land immediately after turning back, the crew descended to 25,000 feet and entered a holding pattern north of Johannesburg. The A380 spent roughly two hours circling while burning fuel to reach a safe maximum landing weight.

The A380 eventually touched down at Joburg’s O.R. Tambo almost seven hours after its initial departure. All passengers and crew returned to the terminal without incident.

Repairs and a second departure

The aircraft underwent maintenance checks and repairs to its weather-radar system. Later that evening, G-XLEJ was cleared to operate as BA54 and departed Joburg at 22:48 SAST on 8 August. The A380 completed its journey to London Heathrow without further disruption.
