Read this and wanted to reply.
What some of you might be interested to know is that for 5 yrs I was long-haul cabin crew with BA. I come from a family of cabin crew and pilots and have always LOVED flying, airports...often the flight was the most exciting part of the holiday. And yet despite all my experience and knowledge, when I had children, I started to feel differently about it, honestly a bit anxious about the whole process. And so I think its useful to understand the relationship between the 2 things and hopefully that's something the psychologist can explain. I have no reason to feel anxious because I have witnessed the safety, training and rigour that goes into flying, I understand turbulence, the sounds of the engine and yet I still do from time to time. Having flown with lots of very nervous flyers (grown men crying uncontrollably for example), it does seem to help to understand the mechanics of what's going on, not just the engines but also why the crew behave in certain ways and remember that hours and hours of training are invested in cabin and flight crew, with the single aim of managing our safety. I also find it helpful to try and block out everyone else and just focus on me in my seat (window seat is easier for doing this, blind down if it helps).
The captain will do a much better job than me of answering all the technical questions but to answer a few quick questions from what I know. The dings are mainly all passenger calls bells (normally because someone's headset isn't working!) or calls between crew between cabins (there are internal phones). Again these are generally all innocous, such as not enough peanuts in the back galley or locating 28f's veggie meal. The dings are def not coded messages!
To the lady who has a fear of vomiting. I myself have the same fear and also a fear of those vomiting around me. It almost stopped me from taking the job of cabin crew in the first instance and is the bain of my life. In my experience (and believe me I am hyperaware of any vomiting activity, it drives my husband mad with my vomiting vigilence), far less people vomit on flights than you would expect and when it does happen it tends to be due to other reasons such as illness, anxiety or just plain exhaustion sometimes on long haul flight. Whole weeks of flying would go past and I would not be aware of any vomiting on board which makes me think that it isn't nausea inducing, unless someone is feeling anxious.
Now, if this thread was about ferries, I wouldn't be as positive. I do not do ferries! Ever.
Good luck to everyone.
