I can not reach you by PM hence I send using mailing list as suggested
1. I have the fix.dat.gz which reflects the latest AIS Japan data
https://aisjapan.mlit.go.jp/Login.doand was provided on Japan forum. I
already sent this to Robin to update but he is too busy to answer and I
haven't gotten any response yet.
2. I have the nav.dat.gz which I corrected all the GS antenna elevation
measuring actual touchdown point. Robin already corrected some of them
since I had reported that RJSF GS elevation is not correct as following
mail. And I notice that this change is not applied FG yet.

I apologise for the delay in replying, but we have been working on
enhancements to my database to support the new features of X-Plane
work is complete, so I am now processing the backlog of airport updates.
I have corrected the elevation of the glideslopes. The FG team should
incorporate this to their database whenever they reload my data.

Subject: GS antenna elevation data is incorrect in nav.dat
At first, thank you for your dedication for these database maintenance.
Now I have found some issues in nav.dat GS antenna elevation data.
GS antenna elevation data of RJSA, RJSC, RJSF and RJSK are all 54 feet
nevertheless other data are around 660, 330, 1220 and 310 for each.
This causes plane crash when I do ILS landing.
Then I checked all the RJ** airport data and found those data were not
That's why the GS slope and PAPI indication has discrepancy.
I was a FFS maintainer once and this GS antenna elevation data was a
adjusted data after delivery the simulator since the slope might be
different because of visual model accuracy.
Therefore this data may be differ between different simulator.
What do you think to keep accuracy of this data?
I'm currently the Flightgear user so Flightgear should have independent
Let me know your thought.
My question is, can I push these files to GIT?
If not who should I ask?
I know they will be modified when V850 scenery will be delivered but it
will be next February or later.
Until that time can we use these my files?
And this also fixes the issue of http://code.google.com/p/flightgear-bug
