Most of which is done on the tax payers dime. Yes, Jeppesen does add
value. For example, they compile it into different formats for
vendors as well as a lot of cross checking and data validation.
However, the real hefty lifting is done by government agencies. As
the end consumer essentially ends up paying for the base information
twice (once
to Jeppesen and once through their taxes), I'll side with the OP and
say
that Jeppesen is indeed overpriced.


And, the companies, Jeppesen and Garmin, aren't in business for the
fun of it.



Yup, and they are welcome to charge as much as they can get for it.
And they
can charge a lot for it because they are the only game in town.
However,
if there was any other source for this information, you can bet I
for one
would be encouraging the competition.


The taxpayers pay for instrument approach procedures and
route/development maintenance.

The nav database is of little use to anyone until Jeppesen does a lot
of work on it.

Special use airspace boundaries are painstakenly reconstructed by
Jeppesen from the arcane rule-making source. NACO has to do the same
to make Sectionals and TACs, and those aren't exactly free, either.

The compliation of airport, nav-aid and comm frequencies from many
sources isn't easy, either.

The taxpayer is being had by the fact NACO gives away its approach
charts. Those are distinct and separate from the development of the
IAP. No other country in the world gives away their approach charts.



That's not completely true, go to http://ais.fi/, click the IN ENGLISH
tab and then eAIP link. You will get the whole AIP, including all
route and approach charts.

A similar system is at least on the Estonian AIP pages.

Because I told speak Fin I don't know what that is all about. If the
data are current that are the exception. And, I don't need to learn
seversl chart formats to fly internationally.


Please read again: CLICK THE IN ENGLISH TAB, and try again.

There is an ICAO standard format for the charts,
which our AIS follows to the letter.
