Answering Re: Approach vectors not provided
I see your point and agree. But still I think is good to have this capability just to avoid being vectored CFIT. Maybe as a last resource in case you haven't set a STAR or minimum safe final app min altitude.
All you have to do is to ensure that the approach phase of your fpl does not go any lower than the FAF (which will never be lower than the lowest MSA) which you can enter in the SID/STAR page after entering the four letter ICAO code.
On a LIMW chart tho the FAF is at 11400 and the lowest msa is 13800 ?
Very interesting approach!
As to any rule, there always is an exception (rules without exceptions are exceptional itself and thus covered by this rule).
Using your own arrival procedure (STAR, transition, or however you want to call it) is the best here, as originally said.
If you want to get vectored (which seems unrealistic here), you could try one of the following:
1. using the IAF altitude (FL150) instead of the FAF altitude here, and set the FAF (IAF) distance accordingly (35 NM?)
2. Include additional waypoints with manually set altitudes for the approach, the last waypoint being the FAF (or very close to the FAF)
But your nautical mileage may vary
