Narrative:

Captain was advised that following mynn (nassau), VOR departure along route BR49V takes flight off route 5 NM although navigation system in aircraft indicates in route. Nassau vors seem to be consistently unreliable. Flight is filed for 12000 ft en route altitude under block flight plans, and crew did not claim traffic conflict, nor was there any conflict stated by ATC. Callback conversation with reporter revealed the following information: callback conversation with reporter revealed that complaints that zqa VOR is frequently notamed 'not operable' and 'unreliable' continue. He is concerned that a traffic conflict may ensue from this NAVAID unreliability. The reporter additionally alleges that WX reporting in the bahamas is often erroneous. His company uses miami as an alternate on fl to nassau flts rather than risk use of an alternate where WX reporting is constantly suspect.
