Narrative

I WAS INSTRUCTING INSTRUMENTS AT ROSEBURG FINISHED; LEADED FOR NORTH BEND; OREGON. COULD SEE WEATHER WAS NOT AS GIVEN (3800 SCATTERED 10000 PLUS BROKEN CEILING); SO AIR FIELD; DECIDED GOOD EXPERIENCE FOR MY STUDENT TO HAVE ACTUAL IFR APCH REQUESTED VOR APCH. CTLR CLRED FOR APCH WITHIN FEW MILES OF VOR. WE WERE ON TOP (VFR). DESCENDED INTO CLOUDS. CTLR REPORTED 400 AND 1 1/2 MILES; NO I REQUESTED ILS APCH. WAS CLRED AND HANDED OFF TO NORTH BEND FSS WHO REPORTED 1000 SCATTERED (AND A HIGHER CEILING I'VE FORGOTTEN). IN HASTE TO CHANGE APCH CHART TO ILS I GAVE UP MY COPY TO MY STUDENT. WE HAD PLANNED TO DO VOR APCH. STUDENT HEADED OUT FROM VOR ON 281 DEG RADIAL. I QUESTIONED IF IT WAS 281 DEG. HE INSISTED IT WAS. I SAID SOMETHING IS WRONG. NDB SHOULD BE STRAIGHT AHEAD; SO GO ON BACK COURSE OF ILS. HE HAD PROBLEM WITH THIS. ON CLRNC WE WERE TOLD MIDDLE MARKER WAS OUT OF SERVICE. I NOW BELIEVED I HAD MISHEARD IT AND MUST BE OUTER MARKER OUT BECAUSE ADF DID NOT INDICATE NDB STRAIGHT AHEAD. BELIEVED SOMETHING WRONG; SO TOLD FSS I'D RETURN TO VOR. WE WERE ABOVE 3000'. THEY HANDED US BACK TO SEATTLE CENTER. I CLIMBED TO 6000 (VFR ON TOP) AND TURNED TO VOR (6 MILES WEST). CTLR HAD SOMEONE IN HOLD AT VOR AT 5000. TRIED ILS APCH AGAIN AND AGAIN ASKED IF STUDENT WAS SURE IF WAS 281 DEG. HE WAS VERY SURE IT WAS. (LATER LOOKED AND SAW HE SHOULD HAVE HEADED 238 DEG). IT ALL LOOKED VERY WRONG. TOLD FSS AND CENTER WE WOULD HEAD WEST TILL ON TOP; THEN CANCEL IFR. WE DID. MY ERRORS: NOT CHECKING APCH CHART MYSELF; BUT DIDN'T IN HASTE TO CHANGE APCH PLATES TO ILS. RUSHED MY STUDENT. SERIOUS 'NO-NO'. SHOULD HAVE STAYED WITH PLANNED VOR APCH. I LET CTLR STAMPEDE ME WITH INCORRECT WEATHER REPORT. OR GO INTO A HOLD TO TAKE MORE TIME. DID NOT BELIEVE ADF AND NDB WERE CORRECT SO DID NOT GO TO NDB TO HOLD AS PLATE CALLS FOR; AND IS NOW SO OBVIOUS TO ME. PLEASE NOTICE NORTH BEND APCH CHARTS. THE CURRENT ONE HAS A '281' BY THE ARROW FROM THE VOR. THIS IS WHAT MY STUDENT READ AND BELIEVED WAS THE DIRECTION TO THE NDB. NOTICE THE LAST DECEMBER 1987 CHART. IT HAS A DIFFERENT NUMBER; ONE NOT REASONABLE FOR A DIRECTION TO NDB AT THAT ARROW HEAD. I BELIEVE THE LOCATION OF THE '281' AIDED IN HIS CONFUSION. KEPT FSS FULLY INFORMED; AND CTLR AS WE WERE HANDED OFF TO HIM. APPARENTLY; RADAR HAD US EVEN DOWN TO 3500 (+); FOR CTLR WAS AWARE WE HEADED OUT FROM VOR INCORRECTLY AND TOLD THE FSS. WE HAVE MODE C AND IT WAS ON.
