This report is general in nature. The following vors located in the eastern USA (specifically northeast) are un-navigable. I have used these vors for yrs and they do not improve. Many vors in the northeast are unreliable. Just talk to any pilot or ATC facility. We receive constant CDI deflection 1-3 dots left or right deflection. 117.7 bkw (beckly, wv). 116.8 psk (dublin, pulaski, va). 116.3 csn (casanova, va). Callback conversation with reporter revealed the following information: captain's aircraft type: MD80. Says numerous VOR stations in the east and northeast are unreliable. Many times the cockpit CDI will deflect left and right as much as 3 dots displacement. The identify signal may come in strong, but the actual course will vary a lot. With the autoplt on and trying to track the course, it will hunt and bank back and forth until the flight crew takes it off and resorts to using heading select to compensate for the poor signal. Reporter claims that pilots who regularly fly in those areas all know about the problem as well as the traffic controllers, but nobody takes any action. Reporter says that it is very frustrating to work with such poor vors and especially when no action is taken to correct the problem. Reporter claims that the problem is continuous and doesn't seem to be related to time of day or, as some controllers claim, magnetic disturbances. Several of the vors he lists are bkw (beckly, wv), psk (pulaski, dublin, va), and csn (casanova, va).
Original NASA ASRS Text
Title: UNRELIABLE AND UN-NAVIGABLE VORS. SPECIFICALLY MENTIONED ARE BKW, PSK, CSN. RPTR ALLEGES THAT THERE ARE MANY OTHERS, PARTICULARLY IN THE E AND NE.
Narrative: THIS RPT IS GENERAL IN NATURE. THE FOLLOWING VORS LOCATED IN THE EASTERN USA (SPECIFICALLY NE) ARE UN-NAVIGABLE. I HAVE USED THESE VORS FOR YRS AND THEY DO NOT IMPROVE. MANY VORS IN THE NE ARE UNRELIABLE. JUST TALK TO ANY PLT OR ATC FACILITY. WE RECEIVE CONSTANT CDI DEFLECTION 1-3 DOTS L OR R DEFLECTION. 117.7 BKW (BECKLY, WV). 116.8 PSK (DUBLIN, PULASKI, VA). 116.3 CSN (CASANOVA, VA). CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: CAPT'S ACFT TYPE: MD80. SAYS NUMEROUS VOR STATIONS IN THE E AND NE ARE UNRELIABLE. MANY TIMES THE COCKPIT CDI WILL DEFLECT L AND R AS MUCH AS 3 DOTS DISPLACEMENT. THE IDENT SIGNAL MAY COME IN STRONG, BUT THE ACTUAL COURSE WILL VARY A LOT. WITH THE AUTOPLT ON AND TRYING TO TRACK THE COURSE, IT WILL HUNT AND BANK BACK AND FORTH UNTIL THE FLC TAKES IT OFF AND RESORTS TO USING HDG SELECT TO COMPENSATE FOR THE POOR SIGNAL. RPTR CLAIMS THAT PLTS WHO REGULARLY FLY IN THOSE AREAS ALL KNOW ABOUT THE PROB AS WELL AS THE TFC CTLRS, BUT NOBODY TAKES ANY ACTION. RPTR SAYS THAT IT IS VERY FRUSTRATING TO WORK WITH SUCH POOR VORS AND ESPECIALLY WHEN NO ACTION IS TAKEN TO CORRECT THE PROB. RPTR CLAIMS THAT THE PROB IS CONTINUOUS AND DOESN'T SEEM TO BE RELATED TO TIME OF DAY OR, AS SOME CTLRS CLAIM, MAGNETIC DISTURBANCES. SEVERAL OF THE VORS HE LISTS ARE BKW (BECKLY, WV), PSK (PULASKI, DUBLIN, VA), AND CSN (CASANOVA, VA).
