Korrol as you have been a member of PPRuNe for 15 months, I must presume that you have read the FAQs and searched for previous threads of this topic?
Your profile states that, as well as being PPL, you work as a 'Manager'. When you are being a passenger/customer of an airline, they are Managing
you. All of the crew manage the whole flight, hardware, software and the pink squidgy-ware that have asked to be transported from A to B.
When you are managing people, you do so with a number of reasons, what your own manager tells you to do, what any regulatory authority tells you (fire precautions etc.) and then your own wealth of experience in the job. That experience will tell you what the majority of your customers are like and the kind of guidance they need. Unless, of course, you only manage THINGS and not people.
Lastly, just because flying is statistically so safe, ask the families of the folks on these flights - all details from the main R&N forum:
- Afriqiyah Airbus 330 Crash
- AF 447 (OK, no survivors but there might have been)
- Air India Express B738
- BA038 (B777)
