Hi,
Speaking as a humble piece of SLF and someone who is a bit of a nervy flyer, that in the first announcment, it's nice to know whats going to happen after take off. I don't mean a long boring run off of the departure, just a simple : "After take off, we'll be climbing to xxxxft and then making a left/right turn towards xxx" or whatever the departure involves.
This helps to settle my nerves 'cause I then know whats going to happen and don't freak out when the plane makes it's first turn(Yes, I do sometimes, sad, isn't it
)
I definitley feel more relaxed when I know what to expect. A friend of mine told me he was on a flight to White Plains, New York(I think) and the pilot came on the PA and let them know about the approach as I believe it's a bit of a freaky arrival. Said it really kept his trousers from turning brown when the aircraft made a steep turn at low altitude a few miles from touchdown!
Anyway, hope this helps.
Cheers!
