FAA Roadmap for Air Traffic and Weather Surveillance
Multi Function Phased Array Radar2Federal Aviation

Air Traffic and Weather Surveillance Snapshot• Air Traffic is expected to more than double
by 2025 and will exacerbate the air traffic delay problem.
• Weather is the major contributor to delaysaccounting for 65% of all delays.
• Current weather and surveillance radar networks are aging (new to 40 years old).
• Many are nearing the end of their service life and will require expensive service life extension programs (SLEP)
• FAA Enterprise Architecture Roadmaps include decision points for replacing current conventional rotating radars.

Cooperative Surveillance• The FAA is migrating to the Automatic Dependent
Surveillance - Broadcast (ADS-B) concept– Transforms the nation's air traffic control system from one that relies
on radar technology to a system that uses precise location data from the global satellite network (i.e., GPS)
– ADS-B is a crucial component of the nation's Next-Generation Air Transportation System
• The Surveillance/Positioning Backup Strategy Alternatives Analysis Report (mitigation of GPS loss on ADS-B): – “recommends that the FAA retain approximately one-half of the
Secondary Radar Network as a backup strategy for ADS-B”– “terminal area primary radar coverage will not be reduced from
current levels”

FAA Enterprise Architecture Surveillance and Weather Roadmaps
2011 - Decision Point (77) initial acquisition review decision for NextGen primary radar system including Wx and Aircraft surveillance requirements
2014 - Decision Point (104) to replace legacy terminal radars (ASR-8, ASR-9) with NextGen primary radar system including Wx and Aircraft surveillance requirements
2018 - Decision Point (91) to replace Wind Shear systems, and NEXRAD with NextGen primary radar system
2020 - Initial Operational Capability for NextGen primary radar system including Wx and Aircraft surveillance requirements

JPDO Alignment
• Next Generation (NextGen) Air Transportation System Integrated Plan
– “Develop a system-wide capability to Reduce Weather Impacts”
– Strategy provides for “Research areas to develop enhanced weather observations and forecasts, and integrate them with decision support tools to enhance capacity and efficiency of the airspace while improving safety.”

Conclusion• National primary radar network
required for foreseeable future• FAA requirement is a subset of the
National Requirement• Collaboration with other agencies
is essential for best value solution• MPAR is a technology research
effort• MPAR could be part of a
multi-agency Family of Solutions
