Aircraft legislation and applicable law
Being one of the lucky guys out there still flying on a regular basis to different countries, I was recently confronted with an awkward situation.
What law is applicable inside the aircraft once on the ground, doors open? Recently we opened doors in a certain country and a person eventually walked in without wearing a mask. The reply was "in this country we don't have such a law". I did remind the guy that the aircraft was not registered in his country, so in theory, the laws of his country don't apply anymore, it's the registration that counts, he has to adapt. I'm usually a friendly solution finder, and after a little chat he went out and looked for a mask without further problems.
Then I suddenly realised we are flying aircraft registered in different countries. Which raised the question: if something would happen, what laws are applicable? The laws of the AOC, or the laws of the country of registration? Which lead me to conclude... my ATPL theory days are long gone...
