Localizer Intercept Vectors

Steals Hotel Toilet Paper
Am I crazy to think that I once read somewhere that controllers should vector aircraft onto a localizer at 30 degrees or less? Is this a requirement, recommendation, or preferred technique? Thanks.

Back Story: got a 50 degree vector to intercept to the loc with a crosswind pushing me even faster. Led the turn onto final a bit so the autopilot didn't freak out and Stevie Wonder its way down final. Guy I'm flying with freaks out about disobeying a clearance.
 
Most basic explanation: 3NM from FAF: 30 deg maximum. Within 2NM-1NM from FAF (and wx is at least 500' above MVA/3SM vis): 20 deg maximum. If the aircraft is RNAV equipped: Can be cleared direct IAF/IF: 90 deg. or less.

The assigned heading can also be a track to intercept at those angles, so winds could also play a factor causing the assigned headings to be more or less that those above. There are a lot of other rules (procedure turns, straight-in clearances, etc) but that's the simplified rule.
 
The vectors are not supposed to result in a track that exceeds the degree minima noted above. There's some judgment involved.

ATC can vector an aircraft no closer than the FAF as well, but only for conventional approaches, and only on pilot request.

There's the rules and there's what really happens sometimes. Pilots are just as guilty of doing the same thing.
 
You can be assigned a heading greater than 30 degrees and told to intercept so long as it's not an approach clearance. At least that's how it's interpreted at my last 2 facilities.
 
To tag onto this.

Can you vector an aircraft onto final for a GPS approach? My 142 big box school insists we can't vector for final for a GPS approach, but I've been vectored for many in the real world in multiple ARTCCs.

Well you big box 142 school is full of crap ATC can vector any aircraft to any approach that is depicted on the radar video map GPS,ILS,VOR.NDB etct.

Try a 90 degree vector to the FAF with a tailwind. Ended that goat rope with a go around due to an unstable approach.

I got something like that the other week with the same results And he put me about 500' high to add insult to injury.

'Da heck is that school smoking? You can be vectored to the final of any kind of approach as long as the facility's radar scope is sufficient.

Gee. I was hoping they were right. It would be nice to feel I accomplished the impossible every time I receive vectors for an RNAV/GPS approach :D

To give them some due, maybe they were talking about RNAV approaches that are not in a radar environment?

I got issued direct the outer marker the other day, from a slight angle. I thought they couldn't do that, also. MSP Approach. @Ozelot ?

Nope not me. But I do clear guys direct the fixes outside the marker and issuing a cross that fix at 4,000 cleared ILS Z 30L.

Figured not. This was maintain 3,000 Direct HILZZ cleared ILS 14 to STP. Wasn't much more than maybe 10-15 degrees intercept and ended up working out. 500 foot ceiling that early morning.

If it's that low a "legal" intercept is 3nm outside HILLZ (says the guy who's had MSP approach put him on final over the marker 500 feet high and thanked them for it). Then again, my boxes aren't your body bag in progress...

Eh, what happens in the back doesn't change what is and isn't legal and safe up front.
