7700 or mayday/pan
Looking for some input from some ATCO’s.
From another thread in Tech log, an ATCO has chimed in with this below.
Mayday Call Query
Any Aussie ATCO’s care to comment on the use of 7700 vs MAYDAY/PAN to get attention?
Cheers

Then do not hesitate to make your emergency call as a MAYDAY - as people have said you can downgrade it later; do avoid the mealy mouthed "we are declaring an emergency" as that is effectively meaningless. 7700 and MAYDAY and you will get everyone's assistance. If the adrenaline level subsequently drops and things are controllable you can always downgrade. But there have been many occasions when relatively small things have escalated - so wake everyone up - no-one in ATC will complain.

The whole “declaring an emergency” seems to be one of those American things.
“Mayday Mayday Mayday.....(details)”
“Are you declaring an emergency?”
“Wilco (sic) we are, roll the trucks”
Company policy where I work is that the decision to use the P or the M word is at the discretion of the PIC. For example I have had to do a flap zero landing into a CTAF with a long runway and made neither call because LDR was much less than that available, and actually the aircraft can be operated with the flap system MEL as long as everywhere is long enough. Whereas a Flap Zero Landing into an airport where you had to defactor the landing distance in order to get in requires a call, as would a flap zero caused by a hydraulic failure.

If you have a PLB/ELT that was designed and constructed in the 21st century, and you’re broadcasting your mayday on the Area frequency, activating the ELT/PLB will not “drown out” anything.
It’s “dumb” to risk it or you being disabled after e.g. a forced landing, such that your precise location is never sent to the satellites.

Mayday is immediate threat to life. Pan = emergency is one step below that which can be upgraded or downgraded if necessary.
When I had smoke in the cockpit after take off, we declared an emergency. ATC told everyone to go around and we made a very neat, tight low level circuit and landed. Couldn't have been simpler thanks to ATC.

We transmitted emergency because we started with a burning smell on the take off roll. Called emergency at about 300 ft. As the aircraft was just out of maintenance we were unsure whether this was a transitory phenomenon due to some form of burnoff of residue or what?
By 500 ft we were turning downwind to land ASAP. Calling mayday was superfluous as we were in the circuit and in constant contact with a most helpful and encouraging ATC/ tower who cleared the way for us.
We stopped on a taxiway and fuel off, master off, mags off and @@@@ off. The firies put it out. Damage about $12000.
If we had been out of the circuit and more than say, two minutes away when smoke started, it would have been a mayday call.
We were @#$%ing lucky.

Scary thing is how long it takes to process what's happening. maybe that's me: I'm a bit slow.
Other thing that was interesting was all the people who appeared from nowhere after we landed, inc lots on bicycles. Normally this field seems deserted, but obviously people in hangers are listening.

Not general aviation but a real world example.
CX138 SYD-HKG, a B-777, diverted to Cairns a short time ago. They were squawking 7700 and added Mayday to their callsign when contacting approach.
They check in at 22:10 into this clip:

From Airservices themselves:
“These phrases alert ATC to the level of response required. If you just tell ATC that you are declaring an emergency, more information on the nature of emergency will be required to enable them to coordinate the appropriate response for you.”
Pretty clear.
