Narrative:

After departing appleton I contacted green bay approach for traffic and was never terminated. I flew a heading of 267 degrees and remained north of the osh 287 degree radial (both VOR receivers) to remain clear of R6904A. However, at 65 mi DME, my LORAN C indicated 1 mi penetration into R6904A. I turned north until the LORAN C indicated well clear. Subsequently I encountered a rising undercast and turned to a heading of 245 degrees to remain north of gbr 260 degree radial. Again when passing R6901A my LORAN C indicated a 2 mi penetration into the restr area. I immediately turned northwest to exit. I subsequently checked both vors for radial deviation but both appeared accurate. The LORAN C also checked normal. At this stage, I am not sure whether I actually entered the restr areas or not. If so, a contributing factor was concern about the observed deteriorating WX situation ahead along our track. I also had the aircraft on autoplt slaved to the LORAN C track direct to mankato, mn, which was an intended fuel stop. The heading was 267 degrees as per the LORAN C calculation.

Original NASA ASRS Text

Title: C182RG PLT HAS NAV PROB AND POSSIBLY ENTERS A RESTR AREA. ALSO DEVIATING WX.

Narrative: AFTER DEPARTING APPLETON I CONTACTED GREEN BAY APCH FOR TFC AND WAS NEVER TERMINATED. I FLEW A HDG OF 267 DEGS AND REMAINED N OF THE OSH 287 DEG RADIAL (BOTH VOR RECEIVERS) TO REMAIN CLR OF R6904A. HOWEVER, AT 65 MI DME, MY LORAN C INDICATED 1 MI PENETRATION INTO R6904A. I TURNED N UNTIL THE LORAN C INDICATED WELL CLR. SUBSEQUENTLY I ENCOUNTERED A RISING UNDERCAST AND TURNED TO A HDG OF 245 DEGS TO REMAIN N OF GBR 260 DEG RADIAL. AGAIN WHEN PASSING R6901A MY LORAN C INDICATED A 2 MI PENETRATION INTO THE RESTR AREA. I IMMEDIATELY TURNED NW TO EXIT. I SUBSEQUENTLY CHKED BOTH VORS FOR RADIAL DEV BUT BOTH APPEARED ACCURATE. THE LORAN C ALSO CHKED NORMAL. AT THIS STAGE, I AM NOT SURE WHETHER I ACTUALLY ENTERED THE RESTR AREAS OR NOT. IF SO, A CONTRIBUTING FACTOR WAS CONCERN ABOUT THE OBSERVED DETERIORATING WX SIT AHEAD ALONG OUR TRACK. I ALSO HAD THE ACFT ON AUTOPLT SLAVED TO THE LORAN C TRACK DIRECT TO MANKATO, MN, WHICH WAS AN INTENDED FUEL STOP. THE HDG WAS 267 DEGS AS PER THE LORAN C CALCULATION.
