Perhaps obvious - maybe it's even suggested to some u/t pilots theses days - but a thought re communicating a problem.....
I worked as an ATCO offshore from 1980 to 1982. The calm was shattered one morning when an inbound (Puma or S61) suddenly broadcast a Mayday, the callsign &, to me, what sounded like a check list & lots of numbers.
All tx/rx was, of course recorded by ATC.
He landed ok on his nearby destination platform & later called me to say he'd had a warning light(s) & was broadcasting some parameters that investigators would like if it had gone wrong & they'd ended up swimming. Smart thinking in a dodgy situation before cvr's ....
