The secret code is:

It opens every flightdeck door in the industry:}

Chill out people, you really think this info is so hard to get hold off? As said the code is only there for flightdeck incapacitation!

Funny, we all have a rant about 'useless' security at airports, but when our code of codes is up for question, suddenly it is all top secret black ops CIA stuff. :)

Childish, I know, but I just had a fantastic mental image of a terrorist clinging to the side of a 737 with a knife between his teeth and inching his way precariously along to the flight deck...

OK guys may be this question is not appropriate to be discussed in public forum but my purpose was very simple, just to know if there is some regulation about it, but I notice that here some pilots are extreme cautious and it's ok forget the question but let me tell you something if some one wants to know this kind of info and more be sure they will get it and don't going a get from this forums.. so pace

and DC-ATE STUPID mmm be a man don't use this to take out ur trauma

toby.

The code is no big secret. All it does is ring a chime in the flight deck. It does not give you access to the flight deck.

I would suggest you ask your local CAA Toby.
