Jepp Low Altitude IFR Chart Question

[cfii2007]

I was looking at a Jepp IFR chart today and trying to figure out the difference between the airports in blue versus green.

I read in the table that blue airports have a Jepp published approach, and the green do not. Yet I found a few greens that do in fact have approach plates (GPS for example).

Anybody have feedback on this?

On the naco charts that means DOD approaches or not.

I think that is the same on the Jepps, but I never use Jepps

It should be as you stated. Which green airport has an approach plate?

[cfii2007]

San Jose RHV....

And regarding NACO low enroutes, yes the brown airports are VFR, blue/green are IFR with some DOD disclaimer.

dod plates (not the enroute charts) are thinner than the ones we use for civil use. the reason is that they have available to use only the published instrument approaches into the airports colored in blue. civil users have the approaches colored in both green and blue..thus our 'thicker' approach plate books.

He is talking about Jepp plates, though.

I have no idea why RHV would be green, then. I don't use Jepp plates at all. Maybe post it in the main forum, so the airline guys can chime in.

his post actually says he's talking about the low altitude charts and the reason for the blue and green colors used on their airport symbols, which pertain to which users have published instrument approaches, as i alluded to in my post.

Yeah, so a blue airport will have both DOD and civilian approaches. A green airport will just have civilian approaches (which can probably still be flown by DOD aircraft *IF* they had the plates) and a brown airport has nothing.

Interestingly enough I heard a tanker on frequency yesterday trying to get into Andrews. I guess they were on the Irons4 arrival and center tried to switch them over to the ELDEE1 (which is an RNAV arrival). They said they couldn't take it and that they only had charts for the Irons4. Don't most DOD flights normally carry a full book (hence why they have limited approaches to begin with)? I guess there could be exceptions to that, but it seemed sort of strange.

Im curious. Since Jeps are not made for the military, is that why there are only two shades, those with an approach and those without?
That would not explain why some fields with approaches are not colored correctly.

Right. It has been a while, but I don't think the Jepp Low En Route have 3 different colors, I think they only have blue and green.

Jepp charts, like the FAA NOS, are not immune to having errors on it. I think this situation is simply an error. What is even more weird is that some approaches have different minimums depending on which brand chart your looking at. KVNY ILS 16R NOS has different minimums posted than the Jepp version, both are current plates.

[exleardriver]

i only used jepp charts and plates at one company i worked for, but that's been since 2001. i thought they were like the naco charts in this respect..maybe they've changed..or senility is setting. cfii2007, since i don't have a jepp low altitude chart in front of me, are they using only green or blue to designate airports? how are they differentiating vfr-only airports?

[milski]

Is it a fairly recent approach? Jeppesen does not update low enroute charts very often, so maybe the approach was introduced after the last update of the chart.

And yes, blue is supposed to designate airports with instrument approaches, green the ones without (aka vfr-only).

2002 for me. I would venture a guess that most active CFIs are using the NOS pubs, because they are so cheap. I haven't seen many flight schools that carry Jepps, because they don't get reimbursement for obsolete charts.

How I was taught:

BLUE = BOTH (civ/military)
GREEN = GA only
BROWN = ain't got POOP

Jepp only has Blue and Green. No brown.

[BobDDuck]

I take back what I said. I was getting my Jepps and NOS confused.

According to the Jepps Intro section a green airport is a VFR only (or no Jepps Approaches published) and a blue airport is an IFR airport with Jepp plates published under the name of the airport.

Digging way back into my dumped memory I am thinking brown airports are a NOS thing only.

Actually, you can order military plates from Jepp for the US. It's just an extra subscription (read "more money!").

The green is supposed to be VFR Only (no terminal charts) while the blue is supposed to have them. Jepp differentiates DOD/Civil/Joint airports through use of the symbols used on the enroute charts.

I've been using Jepps since I started instrument training so I'm pretty decent at figuring out what they're saying. If you have any other questions drop me a PM. Most of the information you could ever want or need is in the very front of the binder.

Another cool thing (since you cant tell green and blue apart at night), the City name on the enroute is capitalized if the airport has an approach, lowercase if its VFR only.

Military airports are designated with a smooth circle, civilian with little tick marks ,looks like the VFR charts symbol for airports with services.

every jepp subsription comes with an extensive legend, havent found anything on the charts thats not shown there.

If I remember correctly, blue has an IAP....green does not (and also is a VFR airport). I've found a few green airports that HAVE approaches, one specifically that has a GPS.

I use NACO (which used to be NOS), due to their low price.

NACO low alt enroutes have brown, green and blue........

That one I can figure out. The Jepp low alt chart seems to elude me.

Eh...it's like anything. Once you get used to it, you'll be fine.

Transitioning over to the NACO TPPs has been a biotch, but I seem to finally get the hang of it.

The Jepp briefing strip is 100x more logical than the junk at the top of the NACO plates.

Yep. I can look at that and get all of the information I need sans the identifier. Mucho better. I like "updating" the NACOs better, but Jepps still win for me.

...maybe someday we'll go EFB.
