Default How do I fly this approach?

Kindly take a look at the ILS runway 26 approach to Astoria (KAST). I tried
to fly this in my sim and I'm not at all sure that I did it correctly.

In my case, this is what I did: I was on V187 from Seattle at 6000. Once I
was within 25 nm of AST, I descended to 4300. About 12 nm away from AST, I
turned roughly north and flew back out to 19 DME from AST, then turned east to
follow the 19 DME arc until I was within a few degrees of the localizer
course. At that point I started a turn towards the localizer and armed the
autopilot, which captured the localizer and glide slope immediately and took
over. About a mile away from the airport I disengaged the AP and flew the
landing by hand.

Was this correct? I'm confused by the references to the NDB and the pointers
towards the east and the procedure turn. Do I have multiple options for this
approach? Was the way I flew it one of them? Or what?

I almost thought that maybe I was supposed to fly to the VOR then outbound to
the NDB then make a procedure turn and come back in. But the DME arc had IAFs
at each end so I finally figured I could just come in towards the VOR then fly
back out to the arc and finally turn towards the airport, which is what I did.



You did it wrong about every way possible. How long have you been
playing real pilot and still don't know the basic rules?

First, by what authority did you descend 700 feet flow the MEA for V-187
simply because you were within 25 miles of AST? The MEA is 5,000 all
the way to AST VOR. That is basic chart reading.

Then, when you turn around at about 12 miles and headed north you
departed protected airspace. At some locations that could kill you but,
of course, not with your MS toy.

The 19 DME arc is available only to non-radar arrivals on on V-27
(R-328) from the northwest or V-27 (R-166) from the south. For any
other arrival the approach begins at AST via the feeder route to KARPEN,
then the procedure turn.

With this one, Anthony, you demonstrate you haven't grasped even the
fundamentals after how many years of ****ing around on this forum.
