    I was only thinking earlier on about this....

    When an aircraft is getting ready to take off the cabin crew do a "cross-check" after the safety announcement and all of that.

    What does this actually consist of?

    when cabin crew arm the doors from manual to automatic they each check each others doors to make sure they ar armed correctly. hope this makes sense

    When they arm the door they are actually arming it so that if it is opened in an emergency the escape slide will deploy and inflate automatically. Depending on the aircraft the door may also have a power assist that aids the opening of the door.

    *Kol* is spot on with this. The function of "Arming" the door- on the lower portion of the doors on passenger aircraft you will see a box. This houses the escape slides. When a door is "disarmed", the door can be opened via the handle without any consequence to the escape slide. On the other hand, basically when a door is "armed", the escape slide is attached to the foor of the aircraft so that in the case of an emergency, when the door opens the slide will stay with the aircraft upon deployment. As *kol* has stated, the power assist on some aircraft comes via a Door Assist Bottle. It basically contains Nitrogen. Its purpose is for an emergency situation when the door is opened..at a certain point when door is opening it springs into life an opens the door very quickly (wouldnt want to get in the way of this!!).
    Hopefully this helps. Needless to say, on the ground (i.e. opening the door for normal purposes)when opening a door its vitally important to ensure the door is disarmed or else you will be explaining an inflated escape slide!!

    Im amazed at the drunks/fools who try to open the door in flight, as if they had a chance against pressure:pac:
