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.

 

[ktulu34535]

can't be

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

 

[Airpiraterob]

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.

 

[Iceman21]

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

Heres the straight poop

ktulu34535 almost has it right.

All caps means there IS an IAP.

Not all caps it is VFR only.

Blue means that Jeppesen publishes a plate for that IAP.

Green & CAP means IAP plate NOT published by Jeppesen.

Green & not all caps VFR only.

Take a look at page 58A Low & High/Low Altitude Enroute Chart Legend. At the bottom of the page near the right is and airport Tidjikja. The arrow pointing to this is explained by the text.

Location name - VFR airport (due to not all caps), no procedure published by Jeppessen. Note: If it was green and all caps, then Jepp does not publish a plate for this airport.

Top left of page 58A TENERIFE airport. IFR airport in blue (all caps there is an IAP for this airport and BLUE = Jeppesen publishes a plate for this airport).

Bottom line is that Jepp doesn't publish all IAP plates for every airport.

Well, 'Shrievy', it helped me find the problem, at least.

A careful review of the material should shed some light on the Jepp introduction and how confusion and misinterpretation abound even among professional aviators.

All caps means there IS an IAP. [/QUOTE]

Not only an IAP, but one published by Jepp.

Not all caps it is VFR only. [/QUOTE]

I disagree. Not all caps means no procedure published by Jepp.

Blue means that Jeppesen publishes a plate for that IAP. [/QUOTE]

I disagree. P. 58A, bottom right:
"(IFR airports are shown in blue)". It doesn't say anything about Jepp procedures are blue, only that IFR airports are blue.

Green & CAP means IAP plate NOT published by Jeppesen. [/QUOTE]

Show me one example post 25 Feb 00 where there is an airport listed with green AND caps (if you can, my whole theory's a bust! ). I don't think you can, b/c Jepp stopped using this format, hence why p. 58A disagrees with p. 55, 57, and 71 (and possibly more). All these pages are dated prior to 2/25/00, when I suspect Jepp made the change.

Green & not all caps VFR only. [/QUOTE]

True, but it's green b/c it's VFR. It's not caps b/c Jepp doesn't publish a procedure for it.

Take a look at page 58A Low & High/Low Altitude Enroute Chart Legend. At the bottom of the page near the right is and airport Tidjikja. The arrow pointing to this is explained by the text. [/QUOTE]

Yeah, do take a look at the text . It says:

"Location name - VFR airport in green, no procedure published by Jeppesen (IFR airports are shown in blue)."

Clearly it says VFR airports are green, IFR are blue. Ok, now we move on to the whole 'caps' issue. Caps indicates Jepp procedures are published (p. 55), since Jepp has always used caps to indicate Jepp procedures, even when all airport names were printed in green ink, as was Jepp policy prior to 2/25/00. Look at p. 55, 57, and 71 if you don't believe me.

If you look at page 55 (dated 3/22/96), you'll see Riverside, California. All caps, all green, and, written right beside it:

"Airport locations labeled in capital letters indicate a Jeppesen Approach Chart is published for that airport and is indexed by that name." There it is, clear as day. Caps = Jepp chart. Even though Riverside is green, this coloring is superseeded by that of p. 58A's text. Jepp includes this page to tell us only that IFR = caps.

Or if you look at p. 57 (dated 4/3/98) you'll see Vogt airport in WALDO IND (all caps, all green). The explaination note, by Jepp:

"Location name - IFR airport (Procedures published by Jeppesen filed under this name)" Caps b/c Jepp publishes a plate for it. Green b/c ALL airports were green prior to 2/25/00.

See p. 71's Houston Intercontinental. It's printed in green. Are we to assume Intercontinental is VFR only? Yeah, right! Coincidence it's published prior to 2/25/00? Nope!


Bottom line is that Jepp doesn't publish all IAP plates for every airport. [/QUOTE]

True, but I'd say the bottom line is Jepps intro is easy to misread. Page 58A is confusing b/c Jepps new colors (blue for IFR, Green for VFR) superseed p. 55 and 57 (and 71 obviously too). The info on the notes on these pages doesn't ever actually contradict p. 58A, since these pages only explicitly tell us caps = Jepp plate, though they seem to imply that all airports are still printed in green, which is no longer the case as you can see by the revision date on 58A. Perhaps the introduction needs to be revised to reflect current charts on all pages, especially considering that it took experienced aviators this long to figure out the revisons on p. 58A which invalidate some of the info found elsewhere in the intro (as far as I can tell).

"Aviator1x1" was likely looking at low Jepp charts that were published before 2/25/00 (where ALL airports are green) and trying to rectify them with current charts and the governing color scheme of p. 58A (where IFR airports are blue). If 'aviator1x1' would only tell us the chart and date of the chart, this issue could be put to bed. If it's before Feb '00, go with p. 55 and 57 (and go get some current charts, as Jepp no longer uses green coloring and all caps together!) If after, then what freakin' chart is it?

The short version

Airport text on current Jepp en-route charts:

Green = VFR only airport
Blue = IFR airport
Caps = Jepp plate published

Green Caps = VFR only airport with Jepp plate (if they even exist, that is )

-Boo!
