Have your aircraft been impacted by DU 00012511 on certain MSN
The implications are in case of DC ESS BUS FAULT the audio cards of the AMU are lost, since all cockpit mikes and headsets are connected to the AMU, all audio means of communication ( including VHF,HF and SATCOM ) are lost,
The use of VHF 2 or 3 do not allow to recover communications ( on these MSN ) , others yes.
Can Airbus correct this DU ?
Through a electrical re wiring or service bulletin, so that one could recover communications bypassing the AMUs?
This DU just came out, so that means that it has been this for a while.
If anyone can shed some light on this, thanks in advance
