Ask 10 different people and you will get 5 different answers. While on the 18.9 DME ARC to intercept the LOC. When can you step down to 8900' from 10000'? After crossing the 350R or 357R from LHO?

I'm not sure if the link works. Sorry.

Link works fine for me, and my answer is 357R. It has the solid triangle and break in the arc line, marking the division between the 10'k and 8900'. If you were flying anything less I wouldn't want to be with you.

I believe you descend down to 8900' after JINUG (R-350). The R-357 is the course you would intercept on the missed approach procedure. If you notice, there's a lightning bolt at the 18.9 DME which identifies JINUG. The R-357 goes passed the 18.9 DME identifying FILOB at the 19.6 DME.

At JINUG, the R-357 defines the holding fix for the missed.

Yeah, I agree with the previous post. JINUG is when you can go down, the R-357 has nothing to do with the arc, it's just for the holding radial.

Another question is when would you step down? The altitudes aren't hard, so there's a lot of benefit to staying a bit higher.

Haven't flown this approach, but it doesn't look like a slam dunk type approach to me. As you hit the LR, you are 17sh out, roughly 5550 AGL with a 10k MSL mountain staring you in the face.

If you start from Malad City, well, that would be a long drone if I expedited down to 10k- 15 miles + 12sh on the Arc + 17sh on final is 44 miles close to the Ground. Hate doing that when NY Approach makes me, don't see the benefit of doing so in Utah

Since the correct answer is R-350 I wouldn't want to be with you, as you can't read approach charts.

There is no break in the arc at the 357 degree radial and there is no fix associated with the DME arc where the 357 degree radial intercepts the 18.9 DME arc. The reference of the 357 degree radial is merely to identify FILOB, the missed approach fix at 19.6 DME, not along the 18.9 DME Arc.

The correct answer is at JINUG where ther is a break in the DME Arc and a notation the denotes a fix ALONG the arc. Once passing JINUG (350 degree radial), you can then descend to 8,900 ft as per the next minimum altitude notation.

I'm hitting my head on this one.:o. I saw the break and the triangle and brain totally ignored the hold and focusing on the solid line section etc...

I will admit I was wrong. How's that one for an internet first?
