The video posted by BlackandBrown explains how to recover comms. This is an old video (produced by TAP Air Portugal training department I believe) and it is slightly outdated but it is well worth to watch it.
And Natstrackalpha also got it right.
During Ecam Actions we must use VHF2 on RMP2 for reception and ACP3 to communicate. For that select Audio Switching (on overhead panel) to CPT or F/O:
- if CPT position is selected > only CM1 will be able to hear + transmit using his/her headphones.
- if F/O position is selected (BEST OPTION) > F/O will be able to hear + transmit using his/her headphones and CM1 will be also able to hear comms via CM2's Loudspeaker.
After Ecam Actions are completed, it is recommended CM1 to be PF. This way CM2 has an easier access to RMP2 and ACP3, and CM1 can monitor communications through the right loudspeaker.
Comms with Cabin Crew it is only possible by using the Handset or via ACP3 (using PA). Cabin interphone is inop.
In relation to RAT extension, it doesn't help in this particular situation, unless we need to recover the Blue Hyd sys.
