Number codes

Other than sounds, the crew also uses numbers to convey messages:
• 7500 is a code used to send a distress message that the airplane is under threat of being hijacked or it has already been so.
• 7600 signifies radio failure.
• 7700 sends a general emergency message.
Flight attendants state that there exist other secret codes that are only known to the stuff of a certain company. Also, they pick a new code at the airport before the flight in order to convey secret messages to the captain in case of an emergency.
So maybe one of the things to bring on a flight is a list of these signals on your smartphone.
Ditch

Perhaps the most famous ditching incident was the one that happened in the Hudson River on January 15, 2009, back then captain Sullenberger also known as Sully has made a miraculous landing on the river due to technical difficulties on the plane.
It was so unbelievable that nobody was killed back then. Maybe their luggage got wet, but their lives were saved.
Last-minute paperwork

If you hear this, then maybe you should start making use of in-flight amusements. Because last-minute paperwork is a code used by pilots to indicate that your plane will not take off at the intended time and that your flight will probably be delayed.
For instance, sometimes the land crew doesn’t finish their procedures earlier or the technicians need to make sure that the plane functions properly.
Cabin Crew, arm doors and cross check

If you are traveling by plane and heard: Cabin Crew, arm doors and cross check. You should realize that it is used prior to taking off and the moment that follows landing in order to notify the stuff that they shouldn’t forget to turn on and off the slides that inflate automatically.
The official aviation rules state clearly that these slides must be always prepared as long as the engines are still on in order to carry out an evacuation when needed. Prior to taking off a special switch is turned on the door to “Armed” mode.
