Old Radar Control Room Features
Large steel structures designed in early 1960s.
Contains a circular 19" monochrome plan-view display (PVD) for radar tracks and other Air Traffic Control (ATC) information.
Each ATC position is hard-wired to support a single sector (limited airspace), or small combinations of sectors.
Modified in 1995/96 to incorporate the Voice Switching Control System (VSCS) digital communication system.
Increasing operational costs due to end-of-life components and worsening reliability.
Constrains operational flexibility required for peak traffic, severe weather, and outages at adjacent facilities.
Not capable of displaying real-time weather intensity as recommended by the National Transportation Safety Board (NTSB).
Viewed as a limiting factor to ATC efficiency by the operators, and targeted by the airlines and other air traffic user bodies as limiting growth and operational efficiency of National Airspace System (NAS).
Little to no built in redundancy to protect against outages.
Supports national releases of software upgrades through individual site actions.
Because of proprietary considerations, difficult to upgrade technology.
Display System Replacement (DSR) Control Room Features
Composite structure designed in the 1990s.
Contains a 20"x20" high resolution color monitor to display radar tracks, improved real-time weather, and other ATC information.
Each ATC position is designed to support any single sector, or combination of sectors needed for operational flexibility.
Designed with human factors inputs to best integrate the VSCS digital communication system, improved flight data, improved weather displays, and recommended improvements in Computer Human Interface.
Increased operational flexibility to accommodate peak traffic, severe weather, or outages at adjacent facilities.
Capable of displaying real-time weather intensity as recommended by the NTSB.
Designed to allow increased efficiency, and supported by the operators as a foundation for further increases in traffic growth and operational efficiency of NAS.
Built-in redundancy to protect against outages.
It reduces training time because functions and controls are similar to the old system.
Replaces the older flight strip printers with quieter, more efficient printers.
Supports national releases of software upgrades through automated distribution.
Centralized monitor and control of the DSR system to include all ATC position equipment and backroom equipment.
Includes many commercial-off-the-shelf products, and designed to allow technology refresh with little to no development.
