Question,
Does an actual Mayday stop ATC bothering you while you are busy dealing with the problem?
It’s just I remember an unrelated incident where a crew dealing with a high workload on finals were interrupted by ATC with some trivia and in attempting to answer the AP was accidentally disconnected and the aircraft drifted off the centreline resulting in a crash.
What I am getting at is does a Mayday pass the onus to the crew to control the comms, ie ATC then become subservient to the crew and in effect a listening out service that reacts to the crews requests and does not interject if that makes sense..
