Cosmo - is there an occasion you'd actually use a PAN call?!
Yes:
"PAN PAN x3, we just saw a ship on fire at position x,y"
"PAN PAN x3, we picked up a mayday call on 121.5, didn't seem anyone copied, I will relay:.."
Basically, stuff that doesn't have anything to do we me. But is an
urgent message and can't wait in cue to be transmitted.
If it has to do with me, I can either call MAYDAY or if no assistance required explain in plain word what my problem is.
