A very nice cockpit footage during a RNAV approach in mountains.
Impressive and amazing when the aircraft goes out of the cloud in front of the runway, in the middle of mountains and high MSA.
Quite very low minimums for a RNAV/ RNP approach (less than 300' AGL), almost like a CAT I Ils

Nice article about construction of such approach, with a lot of natural constraints

Last up to date approach chart, procedure changed a bit since the video, a bit more straigh in.
