Can any Controller help me please?
Does ICAO recommend Pilots to maintain the distress prefix to their callsigns in subsequent transmissions? CAP 413 states that any call following a distress transmission can be prefixed by PAN or MAYDAY if this may have a beneficial effect. I am finding it impossible to find an ICAO ruling or recommendation. Assuming that there is no fixed ruling, would some ATCOs please advise whether they would prefer the prefix or not? Thank you
