Out of date charts on Airnav

You're not supposed to use charts from AirNav for navigation.

The Flight Guide says "not for navigation" too, but their airport
diagrams, readily obvious illustrations of reporting points, traffic
patterns and other details make it a very valuable cockpit resource, as
long as you keep it updated, IMO. If we eliminated all the stuff that
says "not for navigation", we'd have a lot less useful info at our
fingertips.

I suspect the AirNav stuff is identical to the "real" charts,

They *are* the real charts. Airnav links to the NACO website for the
PDF files. They were just lagged a bit in updating the links to the
updated cycle on NACO during the last few days.

Whether a chart is current or not has *nothing* to do with the dates
printed on the edge of NACO chart. Each chart has a serial number
printed at the lower left hand.
(http://www.naco.faa.gov/d-tpp/0613/00142IL16R.PDF for example, has
"Amdt20 06103"). It means the chart is last revisioned on the 130th
day of 2006. As long as the most recent chart on NACO has the same
serial number you chart is still current. It doesn't matter if you
printed it out 3 years ago.

That's why I think it a bit bizarre that so much is still marked "not
for navigation," even when it is manifestly identical to the
"official" materials.

Agreed. I always use the FAA site. Some of the other sites aren't current,
especial near the end of the cycle.

I was planning a trip, and in addition to the standard Jepp charts,
eFlyBook (another saga), I also print out a few of the FAA charts (larger,
easier to read at night, can scribble on them, etc).

However, on downloading and printing a chart from the Airnav website, I
noticed that they were from the last cycle, so might not be valid or
current(??)

Has anyone else noticed this? Are the FAA or AOPA sites any easier to
access and print?

Are there any sites that have current VFR sectionals and/or low
enroute charts to print?

skyvector.com does.

http://skyvector.com/#16-15-3-2886-2532
is the Danbury area.

While I like SkyVector, pay attention to the print in the top right corner:

Don't go flying with this website! Purchase a real chart, and come back
alive to visit us again.

I don't know of any official sources for chart downloads. Even if there
were, printing them would be a beast of a task - especially for any
significant XC.

You could read them on a laptop, which would have the added advantage
of illumination at night.

However, I think all the sectionals are prepared by hand, and they
depend on physical techniques such as overprinting, so you probably
won't see PDFs any time soon. Still, it would be nice to be able to
download scans, or anything. And I don't see why they wouldn't be
free, since they are government produced and carry no copyright.

His subscription ran out so they are now out of date, but Kyler hosts
FAA supplied TIFF sectionals at
http://aviationtoolbox.org/raw_data/FAA/sectionals/ .

Being an electronic format, you can convert them to whatever you want.
Imagemagick worked very well for me to convert them to compressed JPG
or PNG files and store the whole USA on a 1GB memory card to view on a
handheld. It was lot more compact than carrying and unfolding a bunch
of paper charts.

You can't convert from scans to PDF, though. PDF is a lot cleaner.

Airport diagrams and plates are now in PDF format, but the charts are
not. I can see a number of technical problems with converting them,
beyond the labor required to rebuild them from scratch.

This statement is an outright lie.

Start Acrobat, click on "file", "import", and "scan". When done scanning,
Acrobat will convert the scan into a PDF.
