WIZ;
I'm still not seeing the problem- what exactly is it about "blabbing Mayday"- that is, identifying yourself as an aircraft in a legally defined state of distress-that is in any way detrimental to your situation?
Aaah, the voice of sweet reason! In an ideal world quite correct. However in Australia you cannot trust CASA not to launch a vindictive and unfair investigation, aided by the ATSB, that results in your loss of license or prosecution or perhaps both, as evidenced by what happened to Dominic James. I don't know, but suspect, that many emergency situations go unreported for this reason. That can only have a long term bad safety outcome.
My own two cents worth from student days: never try and teach STOL operations using a touch and go methodology.
