hi all,
Torsten Dreyer a écrit :
In real life, pilots (and ATC) uses terminal procedures of
each airport when approaching or departing. Example for KSFO:
http://flightaware.com/resources/airport/KSFO#terminalprocedures
What about adding real SID/STAR procedures to FG? This will
make flying and communicating with ATC in FG more realistic.
Not necessarily. When there is a radar service - and most airports I know do
have a radar service - there are published procedures but they are usually
not used because the approach controller guides you to the final approach by
assigning the pilot individual headings, so called radar vectors.
But there are three problems (as i understand this):
1. Where to find the database of SID/STAR of *all* airports?
They are published in the AIP of the airports country. You can find the
relevant AIP for europe at http://www.ead.eurocontrol.int/ and they change
every now and then.
For a flightplan-like script I made, I use the ones for GoodWay Xplane
(http://www.xpgoodway.com/), I asked for the use of these files to the
devs of GoodWay and they accepted without any problem (including that my
script is GPLed and intented (;)) to be used by anyone), you may contact
them again to ask.
Using them I found that they include some waypoints unknown by our own
fix.dat, so I decided in my script just to ignore them.
The syntax is similar to nav and fix.dat we already use. Some details
have been explained by Alexis to me, but it is quite easy to understand.
2. Database will be large. So we will have another big file
in FG distibutive, such as nav.dat.gz, awy.dat.gz, etc. This
means that FG will get more time to start and will use more
memory (?).
Yes it will be large. It should be an optional feature to load.
Indeed it is not so large, as many aiports are not included I think, but
there are still many.
3. Copyrights and law. Is it ok to use this type of data in FG?
Won't we have law problems with other authors?

I think it could be a cool feature but your biggest problem would be
collecting the data and copyright issues.
Greeting, Torsten
hope my solution could solve these problem and allow you to continue in
your great idea.
