Normal OM Comms Procedure for Multi-Crew Ops. will read something like:
Radio Procedures – Crew Duties
For normal operations both VHF radios should be monitored by all flight crew members. During normal operations the PNF is to make any radio transmissions.
If you haven't flown in a multi-crew operations Frank, then best retire 'hurt' on this one mate, because you're going to go down in 'flames' here (pardon the pun) if you don 't 'concede' I'm afraid.
