On 23 May 2022, an Airbus A320 came within 6 feet of the ground without crew awareness as a go around from a RNP BaroVNAV approach after failing to obtain visual reference. The descent below minimum altitude followed use of an incorrect QNH passed by ATC but not identified as such. The lack of an EGPWS warning was due to the non-current EGPWS version for which upgrading had not been mandated. It was concluded that the regulatory intention in Europe to transition from ILS to RNP approaches had not led to any recognition of the potential impact on operational safety.
