ALF507 and Oldaircrew; My point earlier was that the altitude was the thing that was seriously wrong here, not the distance.

With the QNH being grievously wrong; quite why this crew did not notice their low Rad Alt, readings; quite why it did not call out, (maybe pin-programmed off), quite why PF disconnected the auto-pilot in an A320 family to perform a go-around are pertinent questions. Were they completely conversant with RNAV approaches in A320 family?

At 11:32:24 the PM did appear to hesitate when reading back the QNH early on - so there may have been doubt there, but they presumably convinced themselves that they were wrong and assumed ATC were correct.

Can anyone throw more light on EGPWS - should it have called out?

From old copy of Airbus FCOM:
  • The [EGPWS] reference altitude is computed based on the current aircraft altitude or, if descending more than 1 000 ft/min, the altitude expected in 30 s
    My addition and bold
