I have found the code on the CMS, page 17. There is one situation not mentioned so far in which it might be especially important: DeltaLima DeltaLima 53. Had they not responded, I would have put 7700 in and done what I needed to do to handle the emergency knowing that ATC would vector other traffic around me. When you squawk 7700 you have to use your brains and hands to do other things besides flying the plane and troubleshooting your emergency.
So, finally, here are my questions: Squawking 7700 will be one of the last actions carried out. If you do not maintain control of the aircraft is doesn't matter how long it takes to find it, you're still dead.
Each aircraft is assigned a fixed 24-bit address. Andy Andy 1,152 4 11.
If you are VFR at 3000 AGL and run out of fuel happens a lot, really squawking 7700 is faster than looking up a frequency and the conversation will not be of immediate help anyway. To be frank, I wouldn't even bother replying back to ATC following the standby since they will know quicker than I can call them.
There may be other examples, but for at least in the U. Modes Figure: We are making such material available in an effort to further education and advance flight safety.
Often ATC will ask to squawk 7700 after the initial Mayday call to identify the aircraft not only to the controller you are talking to, but to other controllers responsible for nearby sectors as well.

People have died because the pilot didn't do those things. Aside from pumping down the gear and having no lights, the flight was uneventful from that point on.
In voretaq7's answer, he states that there are three ways to send distress signals, one of them is by the aircraft's transponder. All Rights Reserved. A Wide Area distress, with no need to try to initiate comms, possibly in eighteen different languages to dozens of busy people, who mostly don't expect, and won't be able to quickly understand why you are calling them out of the blue, haha.
