               At some airports, there is a VHF Direction Finder. This is equipment that indicates

               the direction to aircraft that are transmitting on the frequency.




               It is important that other aircraft make room on the frequency when bearings
               are to be given.


               Therefore,  these  messages  are  also  given  higher  priority  than  the  regular

               messages regarding flight safety.




               If there is a bracket in which VDF is written, it means that there are VHF bearings

               on this frequency.




               Here  is  an  example  of
               this  -  again  on  a  map

               section  from  the  VFG

               from  one  of  the  maps

               of EKRK (Roskilde).




               10.1.3.1     Accuracy of bearing


               The accuracy of bearings in flight is given in different classes, which describe the

               maximum deviation from the actual direction.

               Classes of reliability:

                   -  A = ± 2⁰


                   -  B = ± 5⁰


                   -  C = ± 10⁰

                   -  D > 10⁰
