On 19 December 2008, an Aeroflot Airbus A320 descended significantly below its cleared and acknowledged altitude after the crew lost situational awareness at night whilst attempting to establish on the ILS at Oslo from an extreme intercept track after a late runway change and an unchallenged incorrect readback. The Investigation concluded that the response to the EGPWS warning which resulted had been “late and slow but that the risk of CFIT was “present but not imminent. The context for the event was considered to have been poor communications between ATC and the aircraft in respect of changes of landing runway.
