Instrument ID

[Herod]

I've been asked to find which aircraft this would have come from. Presumably British?

Thanks for any ideas.

It sure as hell is not from a Harrier!

BV🤣

[Radley]

TSR-2? Obviously an old instrument. Might be quicker to discount all types that it wouldn't go in.

[ian16th]

Not the Beverley.

[Chris Kebab]

Redifon did a lot of sim stuff and I'm guessing the "68" is 1968; so maybe F-4 related? It's a pretty basic display and not from the aircraft so how about maybe the AI trainers they had at Coningsby?

[Tankertrashnav]

Not the Beverley.

I do wish PPRuNe had a "like" feature, as on Facebook. That definitely deserves a :ok:

[Timelord]

Redifon is a grandparent company of the current Thales, and so it is very likely to have come from a simulator prior to the mid 80s when the company became Thompson then Thales. Lightning maybe?......Edited to add ... maybe not. The Lightening had a strip ASI / Mach meter.

[falcon900]

Are there not only 2, (3 including TSR 2 ) aircraft types it could sensibly relate to, simulator or otherwise?

You would think so but none of the pictures seem to fit so maybe Chris Kebab is right, it is from some other training device. Or did Redifon make simulators for any export customers?

[tucumseh]

The ident label pre-dates the 13-digit NSN days. If necessary, you would put a longer sticky label on it with the full number. That it is blank may, as Chris Kebab says, mean there was no aircraft application as there would be no need to have a NSN.

[t7a]

I suspect you would recognize it if it came from the F27 Herod!!

[newt]

“ The Lightening had a strip ASI” The strip speed was was not fitted to all Marks! Only the Mk 3 and 6 plus the T5 were fitted with it in RAF service. So that ASI could be from a Lightning although as I recall ours had the Mach limits clearly marked!

[Herod]

t7a. Yep, the F27 Super!! Went like the clappers. About 0.3M.

[BEagle]

It's not from TSR-2, SR53, FD2, BAC 221, Bristol 188 or Avro 707.....:confused:

[Lordflasheart]

If we're guessing .... Early model Concorde, Flight test station perhaps ?

Someone just sold something quite similar (Mach 1.3) on ebay for £51.

[Timelord]

Ah yes, forgot about Concorde. And the sim was made by Redifon.

Concorde’s was more sophisticated: https://www.pinterest.com/pin/286823069991756901/

[Timelord]

Instructor’s station maybe?

[Pontius Navigator]

It's not from TSR-2, SR53, FD2, BAC 221, Bristol 188 or Avro 707.....:confused:
I though 188 too but that /68 odds probably the year which would discount those. Also a early for the F4. Concorde however might fit.

[NutLoose]

As it appears to be starting at nearly mach 1.5, perhaps it is a deliberately over-calibrated Jaguar one to lull the pilot into a false sense of speed. :ok:

[NutLoose]

I would have thought Concorde as I seem to remember it was capable of about Mach 2.2

[Jhieminga]

Have a look at the connection(s). If it's purely electric, as I suspect, then I would second the suggestion of a simulator/trainer instrument. I don't think a type from the late '60s would have had a centralised Air Data Computer yet.

[gzornenplatz]

The F4 (first flight 1961) had a CADC

[wiggy]

Err FWIW the F4 first flew in ‘58......but yes I do recall it having a “CADC” or something similar, though I can’t remember the details and I wonder if it was mostly analogue in nature...

As for the instrument in question in the OP I do recall the previously mentioned AI trainers at Coningsby having a somewhat interesting instrument “set”, with the gauges at the pilot’s station having little in common with what was on the actual airframes, so I suppose it’s as good a guess as to origins as any others so far.

[k3k3]

Nimrod 1 had a CADC.

[Bravo Alpha One]

The other day I accidentally caught a few seconds of a programme about the development of the Vulcan by Avro. Appalling film quality, but one brief section showed a wind-tunnel test rig with a very similar looking instrument on the panel.

Apparently the late Roly Falk was regarded as a true gentleman, unlike many pilots these days :ok:
