A GOV SMT PLT PENETRATED R-2306.

Narrative

I WAS TRANSPORTING GOV OFFICIALS FROM LAKE HAVASU; AZ TO YUMA; AZ. APPROX 45 MI FROM YUMA; I CALLED YUMA APCH CTL AND WAS GIVEN A XPONDER CODE. APCH NOTIFIED ME THAT I WAS IN RADAR CONTACT AND TO IMMEDIATELY TURN TO 270 DEGS AS I WAS INSIDE THE R-2306 COMPLEX. I COMPLIED WITH ATC AND BEGAN XCHKING MY NAV RADIOS. I HAD PRESET THE BLYTHE VORTAC 150 DEGS RADIAL ON MY #2 OBS; AND THE BARD VORTAC 345 DEGS RADIAL ON MY #1 OBS (HSI). MY PURPOSE IN PRESENTING THESE RADIALS WAS TO ASSIST ME IN REMAINING CLR OF THE R-2306 COMPLEX TO THE W. I WAS ALSO REFERRING TO THE CB-18 WAC CHART. YUMA THEN TOLD ME I WAS CLR AND TO RESUME MY OWN NAV. AFTER LNDG IN YUMA AND CONFERRING WITH MY PAX; I LEARNED THAT AT LEAST 1 AND MAYBE 2 CELLULAR PHONES WERE BEING USED BY MY PAX. BOTH VOR RECEIVERS IN THE ACFT WERE SIGNED OFF AS BEING CHKED BY THE PXR-VOT IN FEB 94 WITH ZERO ERROR. I CAN ONLY ASSUME THAT THE CELLULAR PHONES COULD HAVE AFFECTED MY NAV RADIOS. I RECENTLY READ IN THE AVIATION SAFETY JOURNAL ABOUT THE PROBS WITH COULD ARISE FROM USING PORTABLE ELECTRONIC DEVICES WHILE IN FLT. I PLAN TO DISTRIBUTE THAT ARTICLE TO ALL EMPLOYEES ON MY OP IN ORDER TO ALERT THEM ABOUT THE HAZARDS OF USING PORTABLE COMPUTERS AND TELEPHONES IN ACFT.
