This might also belong partly to the pilot's thread, but let's see how we go...
In light of a topic which is topping on the New Posts at the moment, in your experience (cabin crew or milehighclub et al.), how many people really keep their seatbelts fastened at designated times (i.e. when seated even with the sign off, or, more critically, when the sign is turned on)?
In a related question, I only know it in Qantas (every carrier is slightly different in the rules), but when the seatbelt sign comes on before landing, the directive by the final PA is, "The seatbelt sign has been turned on. All passengers and crew must now be seated for landing." In reality, we sometimes still see some crew moving through the cabin (of course to return to their designated seat), but is there another "final call" or signal for you to take your seats for landing, or do you doubly confirm this with flight deck somehow? (In some aircraft where I've been, there is a directive from flight deck, "Cabin crew, be seated for landing" which is audible across the cabin. In a similar vein, before take-off many carriers have an audible directive from flight deck, "Cabin crew, be seated for take-off", but Qantas does not do this).
Finally, can you describe how often the crew has to deal with incidents involving smoking (tobacco or otherwise) on board, and what are the kinds of procedures that need to be followed in the case of such incidents? (I realise the last half-question is rather broad as it does depend a lot on what happens as a result of the incident...)
When the seat belt sign is off it amazes me how many don't keep it on. And I have never understood why. Even if you have it on very loose it isn't annoying IMO. Cabin crew wear seat belts in their bunks or seats as do the pilots.
One thing I love about our seat belt policy at Qantas is that it is for everyone. This makes it easier to understand and easier to enforce. When a passenger stands up and they see you seated and secured and you tell them to sit it sets a good example. Crew can call the flight deck to ask for the sign to be put on if they believe crew and passengers are at risk being up.
We have 2 ways that are communicated to us to sit down. All involve the seat belt sign so when ever it is on, you will see crew sit down.
1) The sign will come on followed by "All passengers and crew be seated and fasten seat belts". This indicates that turbulence is expected and that we have about a minute to secure everything and return to a jump seat
2) The sign will come on followed by "All passengers and crew be seated and fasten seat belts IMMEDIATELY". If this is made it is likely that turbulence is already happening. Crew must wedge themselves in the aisle or sit anywhere immediately. We shouldn't attempt to get back to a jump seat.
On landing when the sign will comes on you will notice that there is no PA made from the pilots. When no PA is made by the pilots we know that we are about to land and that final PA that you mentioned is actually made by the CSM.
After we are seated in preparation for landing a final call to all crew is made by the CSM to ensure everyone is seated, although this isn't passed on to the flight deck. This has just being recently introduced.
On the A380 you will notice the seat belt sign flash when the crew are seated. This indicates to crew that the "no contact" period has begun. On all other aircraft this starts when the landing gear is put down, but on such a large aircraft it can be hard to hear this especially from the upper deck. So to indicate the start of the "no contact "period to the crew on the A380 the seat belt sign is turned off and on for a double ding.
The "no contact" period is when under no circumstances are the cabin crew to call the flight deck. It doesn't matter if their is fire, an explosion, you name it - no matter what - crew CANNOT call the pilots to let them know (and if you called they will ignore).
There are two periods of no contact. The first commences from take off roll and finishes after gear up (except on the A380 which is after the aircraft is off the ground - again because you can't always hear the gear). The second commences from landing gear down (or the double ding as mentioned above) until the aircraft completely stops or moves of the active runway.
If someone is caught smoking it is most commonly a verbal warning and an inspection of wherever they were caught to check for smoke and fire and confiscation of the lighter and smokes. A second offence would get them a visit from the police on landing although I have seen a passenger be greeted after being caught the first time. I have dealt with smokers onboard twice in 9 years and once would you believe they were smoking weed!!!
