Almost everyone uses electronic charts, so what is the issue?
Why not allow everyone to use anything that’s available? This unit looks good wait….it’s in Chinese!
Is this good enough? Screen to small? Projected it becomes blurred…insufficient resolution
There are many good systems in the market, but, which ones…who decides?
USCG Navigation and Vessel Inspection Circular 01-16 • USCG NVIC 01-16 allows those subject to chart carriage to take advantage of current electronic nautical charts and navigation technology in lieu of using paper charts & pubs • However only when used on certain—type certified—electronic chart systems (ECS) • Why? Because the USCG is unable to ascertain the functionality and properness of their use on other proprietary system • Type-certification protects the consumer • Thus the NVIC addresses the two exiting ECS consensus standards, the: • International Electrotechnical Commission (IEC) 61174 • Radio Technical Commission for Marine Services (RTCM) 10900
Why develop a companion standard to 61174 (Electronic Chart Display and Information System)? • RTCM allows flexibility; recognizes not all domestic users need a full ECDIS and; • Unique requirements in the USA imposed upon us by Congressional mandates • AIS (2002) • VDR – operational study (2006)
So What and Why RTCM ECS? Some RTCM ECS classes require “less” than the current IMO ECDIS Standards, for example: • Screen size • Navigation Functionality • Accepted Inputs • Hardware requirements
So What and Why RTCM ECS? Some RTCM ECS requirements are “above and beyond” those specified in the current IMO ECDIS Standards, for example: • RTCM ECS meets requirements for interfacing with AIS and displaying information from AIS. NOTE Interfacing AIS in ECDIS is an optional • RTCM ECS meets additional requirements for voyage data recording, and shall provide a Human-Machine Interface (HMI) for an AIS Minimum Keyboard and Display (MKD); and
What is necessary for paper chart equivalency? Through policy we required certain inputs and redundancy. Respectfully request your resolutions: • Information inputs (e.g. Position, heading, AIS, radar, others?) • NOTE Some ECS classes are more akin to a tactical display; others a full ECDIS • Redundancy; although not overtly stated in regulations, mariners could always refer to the next scaled chart if primary chart failed (coffee spill, blew off bridge) • NOTE redundancy = 1 for 1; back-up = lesser equipment
MERPAC & training Fall 2015 - NAVSAC requested MERPAC consider training requirements. MERPAC spring 2016 meeting resolved that: • Electronic replacements to paper charts does not represent a philosophical change to how mariners navigate. • Familiarization means more than user’s manuals • TSAC agreed and will second their sentiment (final delivered fall 2016) Respectfully request your response.
E-Publications CG-543 Policy Letter (2010) superseded by NVIC 01-16: • Allowed 33 CFR & SOLAS V publication carriage requirement to be met electronically except NavRules. • NOTE: Internationally we still recognize only paper for • Int’l Code of Signals • IMSAR Manual • What barriers exists for NavRules? Is there sufficient assurance if given the same parameters as other publications? Respectfully request your resolutions.
Possible future mandate of ENCs; who’s left out? • CGMTA 2004 allows for: • Exemptions (vessels); not necessary for safe navigation for the waters it operates • Waivers (waterways); not needed for safe navigation on those waters • Requesting assistance to: • ID vessels; small groups who clearly warrant consideration • ID waterways types; locations where ENCs are clearly unnecessary Respectfully request your resolutions.
