Maintain 2000 till established

Eh, my flying right now is pretty boring too. I don't get anything except vectors to the ILS these days. I can only reminisce and tell stories about when I was a hardass North Country pilot who ate gravel for breakfast.

Where it wasn't a good day if you didn't go missed on a NDB-A approach down to mins so you could burn enough gas to be light enough to land on the runway with the ILS (and tailwind). Leg 2 of 8.

Never got a chance to do any flying into RKD. I do know that they ended up diverting to AUG a lot with that damn fog!

Heh, AUG, where the nor'easters comes in and the only thing you can use is the VOR to 35, land it hot and high (because that's where it leaves you) and its a long patient slide down the hill that is 35 which is compacted snow. Ah AUG, how I don't miss you at all.

Best part was, until about mid '07 the VOR wouldn't work correctly and the approach would put you on the wrong side of the river and no where near the airport. Thankfully Portland finally called the FAA in and they corrected it for us.

On the approach in question, if you are outside 16.4 DME and your needle is centered, you are not established because you aren't within the area defined by the approach.

Not exactly. If you are established on the MLB LOC at 28 DME, you are still allowed to leave the last ATC assigned altitude because you are, in fact, "Established." Now, since you are beyond 10 miles from FIBOP, you may not descend to 1600 however, if you were at say 9,000ft, you may descend down to any lower altitude on the IAP chart (MSA for example) until you are within 10 miles.

You are right when you say you may not leave 2,000 yet but it is not because you are not within 10, it is because the only altitude you may descend to is the MSA (out to 30 NM from the MLB VOR) but since you are already below that altitiude, there is no lower alt until you get within 10 of FIBOP.

As for the original post, if you hear the words "Maintain ____ until established, cleared ILS 9R Approach" it means, "Maintain ___ until established on the ILS 9R Approach" An approach begins when you are following what is on the IAP chart and since the feeder is part of the procedure (written on the chart), you are then established once you are on the feeder, hence 1,600 once you hit the VOR is fine. (NOTE: In most cases like this, ATC will usually say "cross the MLB VOR at 2,000" or something like that but they could say mx until established)

No. The MSA is an emergency only altitude in the United States. It isn't a published route or approach segment.

I think he means descending to the MSA as a technique. I've seen some FO's do it even on visual approaches. Instead of going from 9k to 2k they go down to like 2,500 or something in the MEM area. In other words, that MSA thing was just a "for instance" and I think thats a taught technique because I've seen it a few times.

If you're on a visual, that's fine for a "technique", but not for executing a published IAP. The poster was asserting that being within the MSA was "established" in the context of an instrument approach clearance and stated "you may descend down to any lower altitude on the IAP chart (MSA for example) ". A literal reading of that statement renders it absurd, but even if you charitably limit it to the MSA, it's still false within the US. Legally, the aircraft must maintain the last altitude assigned by ATC until established on an published route or approach segment, which doesn't include the MSA. It's a very common misconception, just like the idea that the 10 nm circle constitutes the protected area for the PT.

Yes, as stated before as a visual technique I can see it. But for anything else the MSA and (if noted) the ESA are for emergency use only, something I've seen guys get confused about.

I think I'm jumbling the guy's third and fourth paragraph up.
