But it's not going to happen, so as the FODCOM says, instead of wingeing about it, we merely have to find a professional way of dealing with it.
Allocating another frequency STILL won't prevent all those mistaken transmissions from pilots who aren't in the habit of "checking their means" before transmitting and if no reply is forthcoming should think why, before making repeated calls on 121.5 (poor training, poor SOPs, or just
?).
Why
can't some pilots cope with a reduced volume on 121.5 for short while? Beats me!
BTW, 172driver, what you describe with regard to avoidance of airspace etc sounds exactly like a RIS rather than a FIS service.
