ERAM (En Route Automation Modernization) is an FAA Air Traffic Control system designed to "allow faster processing of route requests and in flight route changes". 〔National Air Space Capital Investment Plan Fiscal Years 2007-2011〕 The En Route Automation Modernization (ERAM) system architecture replaces the En Route Host computer system and its backup. ERAM provides all of today’s functionality and: * Adds new capabilities needed to support the evolution of US National Airspace System * Improves information security and streamlines traffic flow at US international borders * Processes flight radar data * Provides communications support * Generates display data to air traffic controllers * The display system provides real-time electronic aeronautical information and efficient data management. * Provides a fully functional backup system, precluding the need to restrict operations in the event of a primary failure * The backup system provides the National Transportation Safety Board-recommended safety alerts, altitude warnings and conflict alerts. * Improves surveillance by using a greater number and variety of surveillance sources * Detects and alerts air traffic controllers when aircraft are flying too close together for both safety and long term planning. * ERAM simultaneously supports many operating modes and complex airspace configurations, driven by thousands of users who want to use the airspace differently. * Allows more radars and flights than the old Host Computer System which ERAM replaces The open system architecture enables the use of future capabilities to efficiently handle traffic growth and ensure a more stable and supportable system. == Implementation == The FAA is deploying ERAM at 20 Air Route Traffic Control Centers (ARTCCs), the (Williams J. Hughes Technical Center ), and the (FAA Academy ). ;Step 1, 2006: Replace the current En Route computer backup system with Enhanced Backup Surveillance. ;Step 2, 2007: Provide controllers real-time electronic access to weather data, aeronautical data, air traffic control procedures documents, Notices to Airmen (NOTAMs), Pilot Reports (PIREPs) and other information with the En Route Information Display System ((ERIDS )). ;Step 3, 2009: Replace the current En Route Host computer air traffic control with a fully redundant, state of the art system that enables new capabilities and requires no stand-alone backup system.〔(【引用サイトリンク】title=En Route Automation Modernization (ERAM) )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ERAM」の詳細全文を読む スポンサード リンク
