This is why I suggested standby pwr for VHF2
That would certainly be a nice mod, Cough!
This 'event' has been 'nit-picked' too far, IMO! It was an unfortunate combination of events that cannot be planned for - and worked out ok.
IF the crew had had the fire chief on box 1 (NB then no ATC contact)......IF the Fire Chief had uttered the advice BEFORE shut-down........IF he had been 'plugged-in' to the interphone............
You cannot provide for every eventuality in life. There was no fault as far as I can see from RyanAir - this could have happened to
any 737 operator.
