British Airways flight BA825 from Dublin to Heathrow declared an in-flight emergency on the morning of Tuesday 1 September, prompting emergency ground crews at Heathrow to stand by before the aircraft landed safely around 40 minutes later.
The Airbus A321neo, registration G-TNEI, departed Dublin Airport at 8.45am and had just reached cruising altitude when its crew transmitted a squawk 7700 code, the international signal for a general emergency, while positioned near Liverpool, according to aviation tracking site Air Live, which followed the flight in real time from 8.26am.
Flight tracking data showed the aircraft make a controlled descent to 8,000ft, where the crew held while assessing the situation with air traffic control. Air Live reported the aircraft then continued its approach into Heathrow, touching down on runway 27L at 9.40am BST before taxiing to a remote stand at Terminal 5 by 9.48am.
A British Airways spokesperson told the Mirror the emergency was declared because of a "minor technical issue" but did not give further details on the nature of the fault.
Emergency services at Heathrow were alerted and placed on standby for the aircraft's arrival, in line with standard protocol whenever a 7700 code is declared, regardless of how the situation is later resolved.
There were no reports of injuries among those on board, and Heathrow's wider operations continued as normal through the morning, with no knock-on delays to other flights attributed to the incident.
