A British Airways jet carrying passengers into Heathrow issued a mayday over London after repeated stall warnings and a sudden loss of key flight protections forced pilots into an emergency recovery manoeuvre now being formally investigated as a serious 'loss of control in-flight' incident.
A British Airways Airbus A320 operating Flight BA919 from Düsseldorf on 6 July was on its initial approach to Heathrow's Runway 27L when it suffered an Air Data Reference (ADR) failure, according to the Air Accidents Investigation Branch (AAIB). The fault affected systems that provide critical information, including airspeed and altitude, to the cockpit and flight control computers.
