FLT CREW COMPLAINT ABOUT VOR IDENTIFIERS WHERE VOR IS NOT CO-LOCATED WITH ARPT.

Narrative

MY CONCERN DOES NOT ADDRESS A PARTICULAR EVENT. I AM WARNING OF POTENTIAL HAZARDS. SPECIFICALLY; LORAN NAV CAN BE CONFUSED BY THE CURRENT USE OF THE SAME LOCID'S FOR ARPTS AND NAVAIDS. GOOD EXAMPLES OF THE PROB ARE PROVIDED BY LGA AND HFD. PRESENTLY PLTS ENTER LGA FOR THE LGA VOR AND THE ARPT. THEY ARE NOT CO-LOCATED; BUT THEY ARE DECEPTIVELY CLOSE. YET BEING CLRED OVER THE CAB AT LGA AND HAVING LGA IN THE LORAN DOES NOT MEAN YOU ARE NAVIGATING IN THE GENERAL DIRECTION OF THE ARPT. EVEN THOUGH THEY AREA CLOSE THIS KIND OF ERROR IN THAT AIRSPACE CAN BE A PROB. HFD; A SIMILAR SITUATION IN TERMS OF IDENT; IS DIFFERENT GEOGRAPHICALLY; ALTHOUGH LESS DENSE AIRSPACE; THE ARPT AND VOR ARE VERY FAR APART. ENRTE TRAVEL COULD BE GREATLY IN ERROR. THE SOLUTION IS SIMPLE. PLACING A 'V' AFTER THE VOR IDENTIFIED OF VOR'S HAVING THE SAME IDENT AS AN ARPT SHOULD BE THE STANDARD PRACTICE FOR LORAN WAYPOINT IDENT'S. AN 'N' COULD BE SIMILARLY USED FOR NDB'S IN THE SAME SITUATION. AN APPROPRIATE FAA CIRCULAR MUST BE PUBLISHED AND AN ADDITION MADE TO THE LORAN SECTION OF THE AIM. IN THIS WAY; THE DISTINCTION COULD BE EASILY MADE BY PLTS; EVEN WHEN THEY FLT DIFFERENT ACFT WITHIN A FLEET. BY ENTERING THE 'V' AFTER THE ALPHABETICAL LOCATION OF WAYPOINT WOULD NOT BE GREATLY ALTERED. I UNDERSTAND PLT RESPONSIBILITY TO OVERSEE NAV INSTRUMENTS. THIS; OF COURSE; SHOULD NOT EXCUSE SITUATIONS WHERE PLTS MISPLACE TRUST. HOWEVER; IT REDUCES THE OPPORTUNITY FOR PLT ERROR.
