You are a low houred new hire pilot on a training flight and the captain is incapacitated and needs urgent medical attention. The nearest airfield is on the nose but is covered in low cloud below minimums and a bit of a cross wind to boot. So you do the sensible thing and declare a mayday and let the thing land itself and request all the available emergency services. For a gold star you will advise atc that you intend to do an auto land and to protect the localiser area - if the airfield has one.
