A320 Emergency Descent
Airbus guidance prior to commencing the descent is “communication establish”. Can I get some feedback of different airline philosophy regards heatset ON/OFF after donning the O2 mask? .
I see a lot of different crew turning cockpit speaker OFF before engine start, however I have always assume assumed the Airbus policy of setting the speaker volume to 1 o’clock position ( during cockpit preparation) had something to do with emergency descent scenario. i.e Mask on and Int On is enough to establish comms?
