Prayers for everyone's safety! I hope it's all just an error in Flightradar and things get sorted out soon. Russia is probably the worst place to accidentally squawk 7500. The russians understandably tend to err on the side of pre-emptive action when it comes to these things.

Quoting sandyb123 (Reply 6): She's squaking 7566 according to FR24. Is anything 75XX hyjacking?
No, only 7500 is hi-jack code...
Some stations even assign you a code which is close to the emergency code, like 7732 or something like that. But that is perfectly normal. Only 7700 is emergency. 7600 is com failure and 7500 hi-jack.

The two planes behind it are squawking 7565 and 7567. Totally normal although ATC 'should' try not to assign any code that begins with 75, 76 or 77, especially as 7500, 7600 or 7700 could be momentarily set as the pilot slowly dials the actual transponder code into the 'box'. This in turn triggers an alarm in their ATC systems.

I thought modern transponder systems made sure this is no longer possible.
Why do Aerospace Engineering students have to turn things in on time?
KAL 007 inadvertently strayed into Prohibited airspace at the time of a missile launch. I think its a little unfair to ascribe the tendencies of the Soviet Union onto present day Russia.

Airvan00.... I think you're missing the point i'm making. Whether its the Soviet Union, or Russia, now, or whichever country... some act before they think... I'm not making judgments, was only passing comment.
Now, can someone please explain how, hopefully! the transponder was on the wrong frequency? Does this occur often ?

The flight hasn't seemed to have deviated from its flight path whatsoever. Also, if it were a legitimate hijacking then there surely would have been reports of it by now, of which there are none (that I could find anyway).

Not sure to be honest but I don't see how unless there is a time delay built in before it transmits any new code it sees. If you have 0000 set and you slowly set each digit one by one, i.e. 7000 then 7500 then 7560 then 7566, you do momentarily have 7500 tuned. Unless your transponder has a button number pad instead of one with dials (like some of our planes)

Yeah, I thought that was pretty much the standard these days. Obviously there are still some older planes that would have the dial (also more dramatic for movies) but I was under the impression that the accidental 7700 or 7500 was a problem that would soon be a non-issue.

Actually it is more of a brand issue. Our older 777s have the number pads but the new ERs all have the dials as we changed brand/model of transponder for the ERs!

Cannot do that. I can only punch in the numbers, from left to right. So when someone gives me the code 7704, I have to enter '7' then '7' then '0' and then be careful and use the '4'...
We pilots can make mistakes. But it looks like it was found out quickly and the flight continued normally.

Don't know whether it is applicable on transport aircraft transponders (I could foresee a complication or two), but on light aircraft we were always taught to momentarily set the transponder to standby, dial in the new code and the return it to A or C mode. There were quite a few occasions when pilots had received something in the 77xx range and had started dialing it in from the first digit back - causing the ATC system to raise an alarm and generally cause a fuss .

2 alternate "safe" methods: "Tune" code into FMS then send to Transponder, or set Transponder to STBY while tuning.
25 cschleic: I used to do this in light planes, then once had ATC ask me why I turned off the transponder or if it malfunctioned. They then waited until it recycl

28 wilco737: Yes, because we pilots are not allowed to make a mistake. But if it happens, the world has to know about it wilco737
29 suseJ772: I was never taught that and I don't think the ATC people I have dealt with would like it if I turned off my transponder in order to input a new code.
31 tb727: I always do it, I was actually taught it when I moved out of light a/c. I was told you weren't flipping through all kinds of codes that way. Sure you
32 TripleDelta: As far as Croatia goes, this method is known to ATC and generally accepted for light aircraft flights (especially VFR - these are not handled by area

34 CX Flyboy: Not something we do as part of our ops. Not sure why though.
35 spudsmac: I do the same thing. STBY, set code, back to ALT.
36 tb727: Well you don't forget and if you do it wouldn't be long before they tell you to check to make sure it is on. It's literally a momentary thing, it too
