MPAR Existing Radar O&M Cost UpdateJune 21, 2007

Radar O&M Cost Data Collection

• Being developed in response to MPAR Working Group Action Item # 2007-1.2, “Complete life cycle cost analysis for legacy radar systems”



Purpose

• Form key input for overall cost benefit analysis for MPAR Business Case

• Systems to be included – 171 WSR-88Ds (NEXRAD)– 47 Terminal Doppler Weather Radars (TDWR)– 135 ASR-9s/Mode-S– 149 ASR-11s– 118 Long Range Radars (LRR)

• ARSR-1 through 4• FPS-20/60



Methodology

• Adopt standardize Work Breakdown Structure (WBS) to ensure consistency between FAA radar and NEXRAD costs

• Collect and analyze historical data for baseline

• Projected costs include– standard inflation– failure rate estimates of major components

WBS # WBS Element Definition

5.1Preventative Maintenance

All activities associated with preventive maintenance of hardware and software, including activities specific for certification.

5.1.1Preventative Maintenance/Certification

All activities associated with scheduled FAA staff and prime contractor conducted non-recurring and recurring maintenance activities to retain a system in a specified condition. It includes all maintenance to accomplish periodic inspections, condition monitoring, critical item replacements, and calibration. It includes servicing requirements (e.g., lubrication, fueling, etc.), the loading of software updates, and certification activities.

5.1.1.1 ARSR-1/2

All activities associated with scheduled FAA staff and prime contractor conducted non-recurring and recurring maintenance activities performed on the ARSR type 1 and 2 LRRs.



Challenges

• Inability to collect detailed cost information• Inability to breakout corrective and

preventative maintenance costs• Inconsistent terminology• Collecting and integrating NEXRAD tri-

agency cost information

NEXRAD Team Composition

• National Oceanic & Atmospheric Administration– Tim Crum– Marty Williams– Russ Cook

• Department of Defense– Mike Spaulding

• Office of Federal Coordinator for Meteorology– Mark P. Weadon

• Federal Aviation Administration– Magda Batista-Carver



NEXRAD Unique Cost Factors

• Archival costs• NEXRAD Radar Operations Center (ROC)• Product Improvement Categories

– Performance Enhancement (e.g., Dual Polarization, Radar Product Generator Refresh, etc.)

– Obsolescence– Reliability (e.g. Open Radar Data Acquisition

(ORDA), trigger amplifier, etc.)



Next Steps

• O&M Cost Working Group– Continue to collect and analyze cost data– Complete final report by October 2007

• PAR Working Group– Use O&M Cost final report as a key input to a PAR
