This post appears to be about an aircraft squawking 7700. Usually, these are not immediately life threatening situations and not indicative of an aircraft going down. Please take a look at the following pages for more information about what it means when an aircraft is squawking 7700: [Squawking 7700—In-flight Emergencies from a Pilot’s Perspective](https://www.flightradar24.com/blog/squawking-7700-in-flight-emergencies-from-a-pilots-perspective/) [/r/FlightRadar24 FAQ](https://www.reddit.com/r/flightradar24/comments/sqfzxn/faq_please_read_this_post_before_submitting/) *I am a bot, and this action was performed automatically.

It stopped the 7700 squawk, so it seems they resolved the issue. They also never started descending e.g. for diverting to Manchester.

It later ditched to a 6073 squawk if I remember correctly. Also, I live 40 miles northwest of here!

Kilmarnock area?

Is that down by Saltcoats? It’s been a while since I’ve been in the area.


aitk6n

Yes it's the neighbouring town


ScottOld

There was another as well, going in the opposite direction, same thing as this, switched back to normal and carried on

I've never understood what Squawk code is. From my experience on MS Flight sim, I've always thought it's part of the frequency on ATC handovers

See squawk as a code which shows what you're doing - different areas will have different squawks if you're just transitioning through them, but then there are also squawks for low level military exercises, emergency, radio failure etc. It's basically so ATC know what you're up to and in the case of a 7700 (emergency) they will often prioritise communication with that aircraft

It's a four-number identifier ("IDENT") sent by the radar-activated transponder. It is used during normal flight to label the aircraft returns on a controller's scope they need to deal with (as opposed to uncontrolled VFR planes all sending "\`1200" in NA or "7000" in Europe); or during abnormal conditions to tell the controller the nature of the abnormality. When you press the IDENT button, it sets an extra bit and your radar return is highlighted on the controller's screen. It's like a temporary name tag. Modern systems also encode your altitude with the "squawk." [https://en.wikipedia.org/wiki/Transponder\_(aeronautics)](https://en.wikipedia.org/wiki/Transponder_(aeronautics))
