It seems that many of my Forum friends have little understanding of what is involved when confronted by an emergency.
The people (mariners) who developer the Mayday/Pan communication model must have had a deep understanding. They developed universally recognised short/to the point phrases that convey a level of danger/threat to vessel & soles on board. No additional communication is required to convey the degree of danger and the initial actions by first responders.
Mayday/Pan is the Primary Communion;:
The use of these terms empowers the PIC, to take whatever action is need, to address the situation
Elicits certain actions in the first responders.
Secondary Communication;
Problem, (engine failure), location, altitude, intention, etc refines these responses. This improves the responders actions, by making assistance more applicable / targeted.
My concern is is the dogmatic way some have treated the Secondary Communication.
By definition, an emergency is a highly dynamic situation. No two emergencies will follow exactly the same pattern.
The PIC must be allowed the freedom to describe what he/she is experiencing - not trying to conform to some theoretical formula.
For sure certain phrases will convey much eg Fuel............, Intercepted........(Turbs) but will not come close to covering every situation.
It is my contention that;
Trying to mandate a particular code/system of communication, in an emergency, is highly likly to inhibit the conveying of essential information.
Pilots are schooled in the basics - Identification (aircraft type & rego), Position (Nm/location/track), Altitude, Intention - this is ingrained/automatic - supplemented by what the problem is, in the PIC's own words, is sufficient.π
