Hi there,

I am currently preparing a flight to the AERO 2013 in Germany (Friedrichshafen). For sightseeing purpose I planned to fly to EDTZ (Konstanz). By coincidence I checked the NOTAMS on the DFS homepage. There I read that EDTZ is closed due to flooding (April 20th - 28th) which is not indicated in SD. Thus the NOTAMS are not reliable to me and not very useful if I am always uncertain whether this info is complete within SD.
What is the source of the NOTAMS and why there are deviations?

Regards,
Oliver
