I could probably write a script that pulls from airport data files.
Really? Where are you located? Maybe a half dozen that are not even a countable cross country from my nontowered with ILS home base.
Are you looking locally or is this for a simulation?
Then why the need for a search query? Just look around. Unless you are in an area where there were few approaches before GPS, there are probably some not far away.
BRL & EOK are two. See how fast?
Went to ForeFlight, tapped on nontowered airports near UIN, looked at the procedure/approach tab. Can probably do that with any EFB or even a site like SkyVector in much less time than this thread has been alive.
I actually wrote a Perl script that pulls from https://aeronav.faa.gov/d-tpp but it's been so long that I don't remember exactly what it does

It wasn’t a search. It was looking at the airport you mentioned on a map and tapping a few others near it. Nothing more sophisticated than that. And I can do it in SkyVector almost as fast as ForeFlight. A bit faster actually. Fewer steps.
That’s basically what I was doing when I started the thread. When I read your reply it sounded like you had a more elegant technique.
Not elegant. Just efficient if looking locally. That’s why I asked the first question.
We do it, but self-NAV for approaches loses a lot (even VFR practice approaches with ATC loses a bit of reality). Personally, I limit it to nontowered airports and always use Approach for towered fields, although there are probably a few where it doesn't really matter.
I don't understand the downside of talking to approach. @Initial Fix are you just wanting to concentrate on the panel without dealing with the radio?
It helps that our controllers are used to the flight school wanting to do all kinds of practice approaches, so they have lots of practice sequencing piston airplanes around to get everyone what they want. I think there's 4 121 flights per day and single digit biz-jet traffic. I'm spoiled because clearance will take your practice approach requests on the radio and give you an IFR clearance to fly them. I asked them if filing made things easier, but they said they'd rather put it in manually.
A Perl script that you don’t remember exactly what it does? What did you call it, ChatGPT 0.1?I actually wrote a Perl script that pulls from https://aeronav.faa.gov/d-tpp but it's been so long that I don't remember exactly what it does
That’s probably the fastest way to do it. Or think about nearby cities of less than maybe 30,000 population that have scheduled airline service.
Depends where and for what. I spent 20 years in Denver and never once did a practice approach without ATC, whether the destination was towered or not. The same was true when I did my instrument training out of a nontowered airport near BDL.
Yeah, as I mentioned above, I'm learning that I've been really spoiled here at CMI. Our ATC is, for the most part, awesome, hangars are relatively cheap, and the shop on the field is great. The GA trifecta.
More like 0.0.1, if it were written in Python/PyTorch.

Great bash script. If I’m reading correctly it provides all ILS for whatever state it’s edited to support (Alaska and others in the shown script ) So I’d just need to add the additional filter for no tower
Opposite of what you said. The /d at the end of the sed is for delete. It’s everything except those states. The name of the file “conus.xml” is also a clue.
Keep in mind that this website is infrequently updated, which I think might have been one of the reasons I wrote the script.This website should show where ILS 's are
Instrument Approach Map
Click the top left icon on the map to activate the drop down box and you can then filter approaches! As with all things aviation, this map is constantly growing and changing! If you find any missin…
Adding -n between sed and the double-quote then changing the /d to /p should invert the CONUS filter.
That's the same site cited in post #31. And I'll re-iterate my reply to that: Keep in mind that it is infrequently updated.
Another IL airport with an ILS and no tower is Galesburg.
