jepp chart question

[aviator1x1]

On the low alt. enroute chart the green airports are VFR
airports while the blue airports are IFR. However on the green airports with capital letters, they have instrument approach procedures.

Why not just make them blue? What is the difference between the blue airports and the green ones labeled with capital letters that have inst. approaches?

Thank you.

hmm

Well I am in Florida and I can't find any green airports with capitals. Then again I am looking at an expired chart right now.

Is there a correlation between the green with capitals and the type of approach maybe a GPS only approach?? Maybe its a circle to land approach only? Maybe its only served by ASR???

Not sure, I'd fire that one off to the folks at Jeppesen, what does it say in the index portion of the charts???

What area are you looking at? I swear I've just looked over the entirety of Texas and can't find one green airport with an approach. For what it's worth, the charts are current.

I had always thought the greens were VFR only.

I fly out of Portland, OR, and I've been studying my Low Altitude Enroute Charts (1 and 2). I can't find any "green" airports with capital letters. My understanding is that all airports having a Jeppesen Approach chart should be in blue only. But then again, I'm only an Instrument student, so maybe I'm wrong.

I think what you are looking at is an airport with a co-located NDB. The title of the NDB will be in green capital letters and may have the same name as the airport.

heres what i recall, on the jepps the green have military approved approaches, the blue are civilian only approaches. i have no knowlege of the colocated facilities. and if im incorrect on anything PLEASE clarify. i need to make sure im right on this. might be asked soon by a grownup.

can't be

Okay... Patrick AFB, Warner Robbins AFB, Moody AFB, Tyndall AFB, Eglin AFB, and Fort Sterwart are all Blue on my charts.

god mabye its reversed, i cant remember in the right order. why dont you look in the Jepp information to find the right answer for us? cause i dont have mine anymore....i need to know too.

 

[ktulu34535]

well i have looked...

In the Enroute chart legend the only defining criteria for an airport having an instrument approach procedure is one that is capitilized. There is no provision for airports being blue having an IAP

In the legend it even shows print in green text being capitalized. So if it is capitlized it has an Instrument Approach Procedure, being green or blue is not the determining factor because a blue symbol for an airport is not even in the legend. This is on page 55

Then later there is a page with sample figures (pg 57) there is an airport in green with capital letters that has arrows saying that it has an IAP.

So I think that only proves that capital letters determine whether or not it has an IAP.

Take the name of that airport that is green and capitalized and take a look and see if there are any IAP's there. I am thinking it may have something to do with GPS approaches.

Not sure
