RLM has provided Software Development services to the FAA and the Volpe Center since 1983. Over the past fifteen years, RLM has played a key role in advancing and maintaining the capabilities of the operational Enhanced Traffic Management System (ETMS). ETMS is used by Traffic Management Specialists to monitor, evaluate and manage air traffic based on current and anticipated traffic loads. Specialists use ETMS to evaluate the projected flow of traffic in the National AirSpace (NAS) and to develop optimal plans for its management, while also ensuring that traffic demand does not exceed system capacity.

RLM is involved in the on-going support and enhancement of ETMS. Our expertise includes distributed communications processing and infrastructure, external system interfaces, and application development.

RLM architected, developed and maintains the network addressing application program interface (API) on which ETMS inter-process communications are based. RLM provides on-going analysis of ETMS network throughput and makes recommendations for enhancements to maximize system network efficiency.

RLM develops, maintains, analyzes, and supports nearly all ETMS external interfaces. These include ARINC, National Airspace Data Interchange Network (NADIN), NAS, international air traffic data providers, and Runway Visual Range (RVR).

RLM provides rapid prototyping and implementation of advanced traffic management concepts and supports their timely assimilation into the ETMS. This requires a broad understanding of the many interdependencies, interfaces and support requirements for the components that comprise ETMS.

In the past fifteen years, the RLM team has been recognized by the DOT Volpe Center in several Group Achievement Awards. The most recent award was for the ETMS Tech Refresh Initiative, a major systems migration of ETMS from the Unix to Red Hat Enterprise Linux platform. RLM was noted for the quality and timeliness of its resolution to migration issues, particularly those related to network addressing application program interface (API). The RedHat migration was completed in one-third of the original scheduled time with the total cost of $10 million, far lower than the projects initial $25 million estimate.
