Are we really that short of frequencies that the DOC cannot be improved by utilising another frequency? And VOLMET doesnt tell you which runway is in use and other pertinent landing information.
The same problem applies to EMA when approaching from the south which is blasted out by, I recall, one of the French ATIS. If the wind is such that it's difficult to second guess the runway and you get it wrong you end up having to reset things halfway through the melee descent. Also better to get the ATIS before descent rather than having only one pilot on ATC during descent (have you noticed the ATIS gets longer will all sorts of disclaimers - increased bird activity - how many owls do they get at midnight?) which has ramifications for level bust.
I think this is an area where frequency allocation has an indirect impact on flight safety.
Of course, in the "olden days" LATCC would tell you the runway in use at destination along with the inbound routing, STAR etc. I guess this was dropped due to RT workload?
