Many thanks all for your input
I am not advocating not giving passenger briefings as I think they are a very useful part of the flight all I wanted to know is when did this became a legal requirement
When I did my air law exams all those years ago I can't seem to remember it being a legal requirement then
I have looked in the 2009 ano and I havnt found any reference in there so I must deduce that it came a legal requirement in 2016
