Narrative:
Almost solid line of thunderstorms approximately 200 mi in length and closely paralleling R464 beginning 75-100 mi east of bradr required deviation north of INS track by 35 mi. Unable to contact arinc on HF because of interference on frequency (caused by WX). Attempted contact with ZHN on 127.6, but out of range. Established communications with ATC west of bradr. Advised them of our deviation due to WX and that we were correcting back on course. Controller stated that radar showed us 35 mi right of INS track for R464 and that a more than 10 mi deviation from track required him to file a report of navigation deviation. I contacted hnl oceanic supervisor by phone after arrival, and explained the WX deviation. He said he had already filed the report for navigation deviation which FAA required. No PIC is going to fly through thunderstorms and jeopardize the safety of his aircraft, crew, and passenger when a deviation is the safest course. Hnl radar is a level 2 radar that paints no WX. When voice communication is impossible, not even an emergency can be declared. Sat communication is the answer.

Title: DC-10 CAPT EXERCISED COMMAND AUTH DURING A WX DEV NE OF HNL ON AN OVERWATER OP. HDG TRACK POS DEV. EMER INFLT CONTINGENCIES PROC NOT FOLLOWED.
Narrative: ALMOST SOLID LINE OF TSTMS APPROX 200 MI IN LENGTH AND CLOSELY PARALLELING R464 BEGINNING 75-100 MI E OF BRADR REQUIRED DEV N OF INS TRACK BY 35 MI. UNABLE TO CONTACT ARINC ON HF BECAUSE OF INTERFERENCE ON FREQ (CAUSED BY WX). ATTEMPTED CONTACT WITH ZHN ON 127.6, BUT OUT OF RANGE. ESTABLISHED COMS WITH ATC W OF BRADR. ADVISED THEM OF OUR DEV DUE TO WX AND THAT WE WERE CORRECTING BACK ON COURSE. CTLR STATED THAT RADAR SHOWED US 35 MI R OF INS TRACK FOR R464 AND THAT A MORE THAN 10 MI DEV FROM TRACK REQUIRED HIM TO FILE A RPT OF NAV DEV. I CONTACTED HNL OCEANIC SUPVR BY PHONE AFTER ARR, AND EXPLAINED THE WX DEV. HE SAID HE HAD ALREADY FILED THE RPT FOR NAV DEV WHICH FAA REQUIRED. NO PIC IS GOING TO FLY THROUGH TSTMS AND JEOPARDIZE THE SAFETY OF HIS ACFT, CREW, AND PAX WHEN A DEV IS THE SAFEST COURSE. HNL RADAR IS A LEVEL 2 RADAR THAT PAINTS NO WX. WHEN VOICE COM IS IMPOSSIBLE, NOT EVEN AN EMER CAN BE DECLARED. SAT COM IS THE ANSWER.
