Safety Recommendation History
From: NTSB
To: National Marine Electronics Association
Date: 7/23/1998
Response: THE BOARD IS PLEASED THAT THE NMEA 0183 HAS BEEN REVISED TO INCLUDE A NEW "MODE INDICATOR" THAT PROVIDES A MEANS OF SHOWING WHEN POSITION RECEIVERS ARE TRANSMITTING DEAD RECKONING-DERIVED POSITION. DATA. ACCORDINGLY M-97-16 HAS BEEN CLASSIFIED "CLOSED--ACCEPTABLE ACTION."

From: National Marine Electronics Association
To: NTSB
Date: 5/4/1998
Response: NMEA STANDARDS COMMITTEE CHAIRMAN, FRANK CASSIDY, "NMEA'S ACTION." A LOT HAS CHANGED SINCE THE LATE 1980s WHEN THE ELECTRONIC EQUIPMENT ON THE BRIDGE OF ROYAL MAJESTY DURING THE GROUNDING WAS DESIGNED. SYSTEMS HAVE BECOME MORE COMPLEX & THE DEPENDENCE ON SHIPBOARD SYSTEMS HAS BECOME EVERN MORE COMMON. SHIPBOARD EQUIPMENT DESIGNS HAVE BECOME MORE SOPHISTICATED, THE DESIGNERS HAVE BETTER TOOLS, & HAVE MORE EXPERIENCE BUILDING INTEGRATED SYSTEMS. NMEA 103 HAS CHANGED AS WELL. THE NMEA 0183 VERSIONS 1.1 & 1.5 THAT WERE IN USE AT THE TIME THAT ROYAL MAJESTY'S EQUIPMENT WAS BUILT CONTAINED ALL THE ESSENTIAL ELEMENTS THAT COULD HAVE PREVENTED THE MISUNDERSTANDINGS BETWEEN THE EQUIPMENT ON THE BRIDGE OF ROYAL MAJESTY, BUT NEWER VERSIONS, STARTING WITH VERSION 2.0, ARE CLEARER & EASIER TO FOLLOW. MORE IMPORTANTLY A VAST AMOUNT EXPERIENCE HAS BEEN OBTAINED USING THE STANDARD; BOTH THE DESIGNERS & THE STANDARD ITSELF HAVE BENEFITED FROM THIS.
