One thing to bear in mind, there is a copyright on ALL the FSNav files so
whatever you decide to do for yourself must remain with you there. I have
almost completed the whole of the UK now with all types of zones and areas
accurate to rw data. It is time consuming work but worth it in the end.
If you are going to add to the airspace.txt file;
Firstly, make a back up copy and keep safe ;o)
1) Open the file in notepad.
2) Turn OFF word-wrap (most important)
3) Find the section that you want.
4) Copy and paste a line if information into another open text file.
5) Work on this copied information amending the details as preferred.
6) When you have completed the coordinates for the area make a "gap" in the
relevant section of the airspace.txt file (go to the end of a line and hit
return) and paste your block of data here.
The Sections (n) are;
3 = ARTCC's
7 = CTZ's (This one I think you mean - shaded zones)
8 = FIR's
11 = TCA's
When you eventually slot your data into section 7, find the correct place as
the sections are arranged with the facilities in alphabetical order.
Try a small theoretical square or zone of airspace first as a tester and you
will get the hang of it very quickly.
The area will start with your first line - starting coord and second coord.
The second line will depict your second coord and third coord.
The third line will depict your third coord and fourth coord.
To finish the area, you need to get back to your first coord, so the fourth
line will depict your fourth coord and FIRST coord.
Thus closing the box and area.
**COORDINATES**
The coordinates used in FSNav are full degrees and hundredths.
I have a small excel file that converts deg mins secs to degrees to six
decimal places which is accurate. Mail me ;o)
If you need more info, drop me a line later today ;o))

Hi Dan,
I was interested to hear that you are working on airspace for the UK. I
did the same thing a few years back and it took a few months to add all the
CTA and Airway info to the required accuracy. Only problem is having to
keep it up to date. I have just finished updating the Clacton CTA and will
have to re-write East Midlands again at the end of this month with the new
CTA configuration there:-)
Its worth the effort in the end though, especialy if you do a lot of VFR
work.
good luck and regards
Philip

Well done mate! ;o)
It sure does take a while and I agree, and worth every hour.
The updates are quite straight forward providing that you have a system that
allows editing.. I have a back-up where all the coordinates and lines are
plotted on the actual FSNav map ;)
The MIL zones and R D areas are also available which completes the full
picture.
All the updates to airspace are currently available from the AIS site.
Regards
Dan
