Russian SU-24 CVR

[Lower Hangar]

Looked around R&N & Mil Av for comments on statement by Russians that they have recovered 'black box' (pictures of CVR) but isnt news !! They also invited West ie Nato to examine it in conjunction with Russian specialists- but none have been forthcoming

Thought crossed my mind :
a Unusual for military a/c to have CVR fitted as std ?!
b Would it reveal voice tx over final minutes of the engagement ?
c Why are we being so coy ?

Flight data acquisition, control and recording systems
In 1997 year in “Aviaavtomatika” named after V. Tarasov” JSC Design Bureau in association with GosNIIAS first time in Russia was created integrated flight data recording system “KARAT-B” on basis of solid-state protected recorder, functioning as airborne crash recorder and airborne automated control system.
Today development and manufacture of solid-state airborne flight data acquisition, control and recording systems (“black boxes”) – one of the enterprise priority directions of activity.
Recording systems for military aviation
High-technology flight data recording systems and recorders for military aviation are developed and manufactured: KARAT-B-25, KARAT-B-29K, KARAT-B-29K-01, KARAT-B-29K-02, KARAT-B-220, ZBN-T. Systems, conforming to the international standards, are installed on aircraft of Mikoyan, Sukhoi, Yakovlev, Yliushin companies. A range of systems is batch manufactured. Protected airborne recorder ZBN-K is installed on sea craft manufactured by “Almaz” Design Bureau.

Or maybe NATO suspects that it is fabricated misinformation from the Ruskies and don't want to give them any credibility.

Ahhhh...gotta love those whiter-than-white unbiased opinion, right? George Junior and Bigotted Tony docet...

Even some fast jets, Lower Hangar. We had a CVR in the Tornado F3. ADRs or FDRs standard fit across the board. And, yes, if Su-24 has a CVR, it will have recorded cockpit voice and RT.

Offer total BS,

Would have to offer encryption keys to West for voice data.

Go figure.

Something I still haven't been able to find out is if the SU-24, whose original electronics date back to the Cold War, may still have had radios that blocked 121.5/243.0. My information is that the Soviets filtered NATO guard channels to make it harder for pilots to defect. That might explain both the lack of response to repeated warnings, and Russian denial that warnings were given at all.

Any old SU-24 drivers out there?

[27mm]

Comrade, I tell you after flying Su-24, all of us old! Na Zdrovye!

[BEagle]

Perhaps there'll be the Russian equivalent of "Stitch that!" on the CVR....

I have such information too, not that it was blocked but they didn't listen to that frequency at all because they didn't expect communication with turkish planes.

It was a routine bombing run, or supposed to be...

It also gives credibility to the notion that the Russians accidentally crossed the border, that the Russians are our allies, 'partners' or peers.

The reality is the Russians repeatedly overflew the border on a regular basis and deliberately ignored radio and multiple diplomatic warning over a period of two months.

Nato and Russia, by mutual consent, are enemies and this event is part of Russia's hybrid war fare against Nato.

The contents of the CVR are irrelevant in that context.

My recollection (which is from almost forty years ago) is that Soviet-era radios were physically incapable of operating on the Western 'guard' channels. So it wouldn't matter if they wanted to monitor them or not, if the radios hadn't received a post-Soviet update.

But be aware that at this late date, I may be dealing with a false memory.

[dazdaz1]

Just a thought, might it be possible that Turkish radar presumed the SU 24 was a Syrian a/c?

any proof? The problem is that turkey has few months ago unilaterally "extended" its border some 5 miles into Syria as a buffer zone, they don't want any planes in that space while Russia still considers it syrian airspace (which it is).

This is M2 version of SU24, they have updated radios but pilots still have to choose the frequency.

nope, it was only russian planes operating in that zone and turks were full aware of it

When you go back to the Foxbat that V. Belenko flew into Japan, yes, its crystals/radio sets had but a few freqs available to the pilot.

Since the wall came down in 89, the Russians have had 25 years to put in dialable and frequency agile avionics. I won't guess at what they have chosen to do, but a decision to use more flexible kit would not be too hard to make.

OUCH!

More fun with Turks and Russians.
Russian Destroyer Fires Shots At Turkish Ship While Transiting The Aegean Sea

A Russian Kashin class destroyer seems to have made not bones about how to communicate with a Turkish vessel (reported as a fishing vessel?) due to being with in 2000 yard CPA(perhaps?). (I get the feeling that the Russian Navy has a similar concern to the US Navy when it comes to CPA and risk of collision). The shots were fired across the bow, reportedly, at 1800ft/600 yards range.

I can just see the conversation between the conning officer and the captain.

Sir, Turkish vessel CPA predicted at 400 yds.
That's a bit close LT, raise him on Channel 16
He's not answering sir.
Try the other frequencies on that card.
No reply, sir.
Flash the lights at him, ready mount 31, one practice round.
CPA now looks less than 400 yards sir.
That guy is either an idiot or up to no good. Ready mount 31. Keep calling him.
No reply sir, no change in course by the vessel.
Fire one across his bow and see if it gets his attention.
Mount 31, with one round, fire!
*BOOM*
Turkish vessel changing course to port, sir. CPA opening.
Good. Quartermaster of the Watch, mark the log, I expect to get some radio calls soon ...

Even so, if the radio doesn't continuously monitor guard channel regardless of what frequency the radio is set to, for all practical purposes they do not have guard capability. This still explains how the Turks could have sent (I assume on guard) what the Russians didn't hear.

[peter we]

any proof? The problem is that turkey has few months ago unilaterally "extended" its border some 5 miles into Syria as a buffer zone, they don't want any planes in that space while Russia still considers it syrian airspace (which it is).

The five times the Turks summonsed the Russian Ambassador and lodged an official complaint.

Also, shooting down the Russian aircraft was proof enough that the Turks were unhappy. A 10 mile exclusion zone was mentioned as normal to avoid incidents, the Russians obviously were not the slightest bit concerned about the consequences.

Corrected.

so?! it doesn't mean they were right any of those five times (though they possibly were couple of times), because of aforementioned exclusion zone Russians obviously didn't agree with

A 10 mile exclusion zone was mentioned as normal to avoid incidents, the Russians obviously were not the slightest bit concerned about the consequences.

they should set the exclusion zone in their own airspace, what right they have to tell the other country what to do with its airspace?! Syria has legitimate government which summoned Russians to help them, Russia has all the right to fly wherever they want in syrian airspace, other countries not so much.

Turks could have sent (I assume on guard) what the Russians didn't want to hear.

do you seriously believe Russians would go to provoke them with a practically defenseless bomber (even anti-IR pods were not present)?!

[teeteringhead]

There was some mocking of the transcript on a programme one watched recently, as the the transcript seemed to include the words "en garde" suggesting offensive intention.

Despite my shouting at the television, the BBC didn't realise it was (almost certainly ) "on Guard"! But hey, that's the BBC
