Slightly amusing is the instruction about turning off electronic equipment. They don't mention pacemakers and hearing aids, both of which these days may well have radio transmitters in them - as may insulin pumps, and other medical implants.
Why do you think electronic equipment needs to be switched off for T/O and landing?
A mobile phone, ipod, laptop or walkman (do they still exist?) in use during an emergency would hinder not only that passenger but people around him/her as well.
Pacemakers and hearing aids on the other hand would greatly help said passenger to get out in case of a mishap.
The reason for nearly all these rules (not listening to your ipod, dimming cabin lights for night T/O, opening window blinds, etc) is 'because if we crash we want you to be able to get out'. Maybe those words should actually be included in the briefing, although this might be seen as a bit too confrontational.
IMHO Easyjet's briefings are far clearer than those of Ryanair, especially when the crew member actually making the briefing is of Spanish (previous Air Futura wetleasing) or Eastern European origin.
FR safety briefings are done from a tape. Don't know what other airlines do.
All EZY and FR safety briefings are after pushback, once the Captain has been given clearance for taxing.
Don't know about EZY, but at FR the CC start the briefing as soon as the doors have been closed. This might well be before or during the push back, and has nothing to do with the captain receiving clearance to taxi.
