Regarding the exit briefing... just wondering what was covered in the 'old' and what you now have to add? Just that with my flying, we always had to tell the pax what they were looking for (i.e. fire, obstacles, water etc) and when to move (the "evacuate" command)... what do you mean by new 'level of detail'?
And you're right, I think it may scare the pax a little, but they dont have to sit ther eif they don't want to!! Always plenty of people willing to sit there... whether they would actually do well is a particular pet subject of mine, but that's for another thread (which has already been covered
)
