Not sure if this is the best place to ask this sort of question, apologies if not but will learn where it is moved to.
In the
The Aviation Herald article it refers to the A320 losing communications due to electrical failure. And then says that the flight crew managed to establish contact, declared emergency then landed.
My question is should the radio(s) (I would imagine there are more than one) become unserviceable what are the available (by this I mean not just happening to have a vhf or cell phone handy) options for declaring an emergency - if any - or is it you proceed with caution relying on ATC to be on the ball and clear the path?
I dont doubt this will differ from aircraft type but was just wondering what would be happening had the A320 in the article not been able to achieve communication.
Cheers
