A transponder (short-for transmitter-responder[1] and sometimes abbreviated to XPDR,[2] XPNDR,[3] TPDR[4] or TP[5]) is an electronic device that produces a response when it receives a radio-frequency interrogation. Aircraft have transponders to assist in identifying them on air traffic control radar; and collision avoidance systems have been developed to use transponder transmissions as a means of detecting aircraft at risk of colliding with each other.[6][7]

Air traffic control units use the term “squawk” when they are assigning an aircraft a transponder code, e.g., “Squawk 7421”. Squawk thus can be said to mean “select transponder code” or “squawking” to mean “I have selected transponder code xxxx”.[6]

7700 is for EMERGENCY if they landed on the water (slide found) then this code should have come up from the transponder, but it didn’t? when it when off radar at 2319 according to flightradar24 site’s snap shots of it’s last flight before crashing into the java sea. And if it landed on the WATER why is it broken up into 5 parts? (as what’s been spotted)

the idea girl says

looking at what a SQUAWK Code is.  It’s for the Transponder, which stopped sending out signals on the Flightradar24 screen around 2319 on 2014 12 27, and I have to look at all the screen shots I took to see if it changed yet.  I don’t remember it going into the 7,000 range, it was in the 3,000 codes.


Emergency Transponder Squawk Codes


Below are the 3 squawk codes every pilot should commit to memory:

7500 – Hijack
7600 – Lost Comm (radio failure)
7700 – Emergency

An easy way to remember this: 75 taken alive, 76 technical glitch, 77 going to heaven.
