I don't know when you'd need to be tuned into both frequencies at once in this case. I'm thinking that you're referring to requesting oceanic clearance. When that happens, you completely make the switch over and are not required to be on the domestic frequency while obtaining it.

Hello Josh,

That is required to take entry and Air defence clearance before entering few FIRs as stated in their AIPs. You need to take the clearance while maintaining listen watch of the tuned ATC.

Thing is, those procedures were designed for aircraft with two (or more) pilots. From what I know, those procedures intend for one pilot to stay on the original domestic frequency while the other tunes to the new frequency. Since there is (usually) only have one pilot flying the aircraft on VATSIM, usually the controller just transfers the pilot over to the clearance frequency without any requirement to monitor.

#506846 Lots of reasons to use two frequencies at once... Would be nice if the volume could be adjusted independently, however.
