My last ‘proper’1/2 mile SRA on a 430 was at Luton in the mid 80s, Finnair MD80 in a snowstorm on 08, he went around and Diverted to Stansted! The radar had a meltdown shortly afterwards…….
Not quite on topic, but twenty years ago I was based at Kai Tak. A typhoon was in progress and the eye passed right through the Territory. As it did so the wind swung right round as expected. Many aircraft had already diverted or asked to remain in the hold, but a Middle Eastern airliner had taken two attempts on 13 and gone round each time. The crew were then informed that there would be a few minutes delay as the runway was being changed to 31; they were then given vectors for that. ATC then informed them that there was a further delay until the ILS came on line and to expedite they were offered a PAR approach to 31 instead.
The crew declined, saying that the aircraft didn’t carry PAR equipment! . Instead, they diverted....

I always thought it was a fun bit of kit

At Luton the 430 was only ever used for talkdowns, but on my validation the CAA examiner asked if I could use it to reposition the aircraft which had done my first run for the second……needless to say I failed miserably!
Several posts have described SRAs as challenging. I certainly agree! Juggling with the variable polarisation, long pulse/short pulse, FTC [fast time constant] aerial tilt whilst keeping up the RTF chat and keeping up with a high approach speed not to mention sorting out the blips from clutter! Challenging indeed. But as an earlier poster said, it was very satisfying knowing that your own skill had made a significant contribution. Sadly modern navaids, SRATCOH and the growth of the rule book took much of the fun out of ATC.......for me at any rate!!
Have a look at the Instrument plates listed in the AIP for the larger UK airfields. Those offering SRA's will have dedicated approach plates shown.
I did one for practise at Chester/Hawarden last year but got stung for an 'approach fee' of £30. And I'm a resident!

Also Newquay have in recent history offered them for controller training. Gloucester still have an AIP entry for a SRA to 0.5NM. I think the modern radars with digital pulse compression have a "large" minimum range and hence the 2NM SRA.
and to expedite they were offered a PAR approach to 31 instead.

I'd like to see the process of setting up the 430 by positioning the final approach line between the PEs from the two reflective markers either side of the runway, and then aligning it with a PE from a church, get through a safety case ! I also remember a controller doing a 1/2 miler to downtown Luton because he hadn't checked that the line was in the right place.
Also, it is worthwhile remembering that Engineering are working on the scanner before considering turning it on for a TOW alignment check...... Luckily they heard the turning motor come to life, and jumped off the ladder.
Also remember doing a 1/2 mile SRA for my validation on 'mad alfonse', the daily Baron arrival. Luckily he flew the ILS and ignored my headings.
SRAs today....no thanks, consign to dustbin of history and stick with PBN.

Brings back memories of my approach radar training at Auckland International in 1978 using a Marconi 264 (50cm) radar with 2NM SRAs. Target was always one of the Civil Aviation Ministry's Piper Apaches (PA23) flown up from Wellington specially for us 'players'. After doing about 10 SRAs that day, I never did another during the rest of my career.
For bigger 430 issues there was always…….Basher Dave!
I wonder if the head gear was actually turned using a Ford Cortina fan belt, as was often alleged? Of course the 08 ILS installation was the beginning of the issuance of the UB40 for the poor old 430. Which, as I’m sure you’ll remember, decided to go out with a bang one night some years later….
