Procedure Turns

The retired life provides plenty of time to read. Here is another question posted on one of the flying forums that I often check into. What are your thoughts, is this PT required?

In the VOR approach for KSYI, if I'm coming in from the North on a heading of 180: (red Arrow)

Cleared for the approach. Not on vectors.

1. Do I need to pass over the SYI VOR first?
2. Do I always have to do the course reversal?


FAR Part 91
 
Section 91.175 Takeoff and landing under IFR.
 
(a)Instrument approaches to civil airports. Unless otherwise authorized by the FAA, when it is necessary to use an instrument approach to a civil airport, each person operating an aircraft must use a standard instrument approach procedure prescribed in part 97 of this chapter for that airport. This paragraph does not apply to United States military aircraft.
 
(j)Limitation on procedure turns. In the case of a radar vector to a final approach course or fix, a timed approach from a holding fix, or an approach for which the procedure specifies “No PT,” no pilot may make a procedure turn unless cleared to do so by ATC.
 
The AIM states:
5-4-6. Approach Clearance
4. If proceeding to an IAF with a published course reversal (procedure turn or hold­in­lieu of PT pattern), except when cleared for a straight in approach by ATC, the pilot must execute the procedure turn/hold­in­lieu of PT, and complete the approach.

5. If cleared to an IAF/IF via a NoPT route, or no procedure turn/hold­in­lieu of PT is published, continue with the published approach

6. In addition to the above, RNAV aircraft may be issued a clearance direct to the IAF/IF at intercept angles not greater than 90 degrees for both conventional and RNAV instrument approaches. Controllers may issue a heading or a course direct to a fix between the IF and FAF at intercept angles not greater than 30 degrees for both conventional and RNAV instrument approaches. In all cases, controllers will assign altitudes that ensure obstacle clearance and will permit a normal descent to the FAF. When clearing aircraft direct to the IF, ATC will radar monitor the aircraft until the IF and will advise the pilot to expect clearance direct to the IF at least 5 miles from the fix. ATC must issue a straight­in approach clearance when clearing an aircraft direct to an IAF/IF with a procedure turn or hold-in-lieu of a procedure turn, and ATC does not want the aircraft to execute the course reversal.

7. RNAV aircraft may be issued a clearance direct to the FAF that is also charted as an IAF, in which case the pilot is expected to execute the depicted procedure turn or hold­in­lieu of procedure turn. ATC will not issue a straight­in approach clearance. If the pilot desires a straight­in approach, they must request vectors to the final approach course outside of the FAF or fly a published “NoPT” route. When visual approaches are in use, ATC may clear an aircraft direct to the FAF.

Ok, if you read all the way through, thanks.  My thoughts on this subject are as follows. Yes, the procedure turn (PT) is required since not on vectors to final (VTF)and there is no, slice of the pie, for lack of a better description that states no PT.
