From the NOTAM system:
KDPG MICHAEL AAF (DUGWAY PROVING GROUND)
M0068/06 - IT HAS COME TO OUR ATTENTION THAT INDIVIDUALS ARE USING THE AIRNAV WEBSITE AS A PRIMARY SOURCE OF AIRFIELD INFORMATION. THE iNFORMATION CONTAINED ON AIRNAV'S WEBSITE IS NOT CREDITABLE. FOR INSTANCE OUR INFORMATION HAS NOT CHANGED ON AIRNAV'S WEBSITE IN SEVERAL YEARS. WE HAVE TALKED TO AIRNAV, AND THEY TOLD US THEY GET THE LATEST INFOMATION FROM THE FAA. IF THIS WERE TRUE OUR INFORMATION WOULD BE CORRECT. 14 AUG 20:22 UNTIL 02 OCT 23:30
So here is a comparison of the latest DoD IFR Sup info and AirNav:
From latest IFR Supplement:
COMMUNICATIONS - CTAF - 126.2 CLOVER CON SOUTH - 134.1 363.5 FIRE STATION - (E) 126.2R DUGWAY RANGE CON - 36.1 126.2 270.0
From AirNav:
CTAF - 270.3 FIRE STATION - (E) 126.2R RANGE CON - 36.1 CLOVER CON SOUTH - 134.1 363.5.
The AirNav data is from the FAA ATA-100 CD that is being highly touted by some on the net. Based on my last monitoring trip to that area the IFR Sup information was accurate which means that the ATA-100 has missing info and errors.
