CVR
Re aural altitude alert:
As per AAIU report:
The Commander had the moving map displayed on her MFD and the Co-pilot had weather radar displayed on his MFD.
The CVR recordings indicated that the Co-pilot was using the weather radar to identify terrain features.
The Rad Alt provided a callout of “ALTITUDE, ALTITUDE” 26 seconds prior to the initial impact. The Commander identified the reason for the aural alert as a small island below the helicopter which she said was “just a small little island... that’s B L M O itself”. At the time of the aural alert FDR data placed the Helicopter in the vicinity of an outcrop of two rocks, Carrickduff and Carrickad, which are located approximately 0.65 nm to the west of the Black Rock.
