Northrop Grumman Corporation announced that its latest VisionMaster FT (VMFT) software now includes ADMIRALTY Information Overlay (AIO) as an integral element of its Electronic Chart Display and Information System (ECDIS) based navigation system making additional chart information available to ship’s navigators.
In the past, navigators have relied on the ADMIRALTY Temporary and Preliminary Notices to Mariners (T&P NMs) to manually update their paper charts. AIO is a free service included with the ADMIRALTY Vector Chart Service (AVCS). The overlay contains worldwide T&P NMs to be used in conjunction with ENCs. AIO is also the only service to include ENC Preliminary Notices to Mariners (EPNMs), the result of the ADMIRALTY Assurance Program, a comprehensive review of the world’s Electronic Navigational Charts (ENCs) undertaken by the UKHO to identify and resolve significant differences between ENCs and existing paper charts.
