A 30 degrees intercept is need, if there is already a turn with 30 degrees in your STAR/Approach, so Yes or ATC will vectors you with a 30 degrees intercept (no need if you are 20nm away)
Starting at the FAF? Sometimes, it can be quicker for controllers to take you off of your filed approach and give you vectors, but this shouldn’t always be the case.
Oh, are you referring to an approach where the IAF is also the FAF and you have to fly the procedure turn? Those are fun, but sometimes a tad difficult to do under ATC control with what we have available to us. As I mentioned, things are always improving, so maybe one day!
I totally look forward to this on the sim…hearing something like ‘N12345, you’re 3 miles from BUDDE, maintain 3000 until established, cleared ILS approach’.
