aviatorhi, sevenstrokeroll -- perhaps you've answered a question that is different from the OP's?
whenever I go to a place where non US regs are in place I review the Jepps for any pertinent procedural information.
Please forgive if this appears to be advice on how to suck eggs, but honestly, I don't think that the Jeppesen Chart Legend pages provide adequate guidance on how PANS OPS procedures are flown.
As aterpster, gf and upper air have noted, in a non-radar environment,
PANS OPS procedures may require an alignment hold that is flown
prior to the course reversal.
The requirement to fly or not-fly the alignment hold is dependent on the direction of arrival at the specified fix.
If the arrival route is outside of the "direct" entry sector -- i.e., "Entry Sector" and "Sector 1" below,
the alignment hold becomes a mandatory part of the Initial approach segment.
Following are the figures cited in aterpster's "red boxed" directive.
The following charts illustrate alignment hold concepts.
Prior to Base Turn (not required from TISAD):
Prior to "Procedure Turn":
If your FMS is approach-capable, it's important to note that the approach in the database won't contain the alignment hold. When required, the hold pattern will have to be manually inserted into the active route by the pilot and flown
prior to executing the specified course reversal.
These PANS OPS concepts are frequently omitted in TERPS/USA IFR training so it's not surprising that the core of the OP's question may have been missed.
