Thanks for the charts. Sporty as you say. I'd like to see the Magenta Line kids try that.
I'd say they do it about 3X a day on average. Alaska airlines services it daily. Flip the airport around and look at the Gastineau channel that leads up to RWY26. Alaska uses an RNP approach that goes up the 1.5 mile wide channel flanked by mountains rising almost immediately up to about 3000 ft. Hairy to say the least.

Page 13 has a copy of the RNP approach down the channel.
Anyway, back to the chart, there's a special approach that follows the same track, just with much lower MDA, 1000 ft. The trade off if I remember correctly is a healthy FPNM climb gradient. The training requirement of the 8260 for the approach requires sim training with graphics specific to JNU or in aircraft. Funny enough, it doesn't state any currency requirements like other specials.
