Presented to Friends & Partners of Aviation Weather AWTT PROCESS UPDATE Presented to Friends & Partners of Aviation Weather Rick Heuwinkel, ARS-100 October 8, 2003

Outline Users’ Concerns Re: Input to FAA Requirements Process Map of Current User Input Points AWTT Role Approaches to Solutions Roadmap Input from Expert Users S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

Requirements Process: Common Complaints Present development process yields a patchwork of multiple, overlapping, and potentially inconsistent products Products are introduced without consideration of regulatory impact Providers define WHAT products are required and HOW they will look and then ask users to approve after it is too late to make changes S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

User Input to Aviation Weather Requirements ATA MetCom CAST JSC AWTT User Meetings RTCA Ad hoc (e.g., GFA) ICAO Ad hoc meeting with associations IATA FAA Low Cost Moderate Cost Expert Input Oversight Direct written or voiced complaints from users FPAW MNS & Requirements AWRP PDT user teams UNAs System development teams: TDWR LLWAS ITWS CWIS CDM Wx Apps Team S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

User Input Summary Numerous groups have input to requirements, overall investment is substantial Same representatives serve on many groups, individual commitment is substantial Some groups provide needed oversight on a broad range of issues Other groups provide technical expertise on design of specific products Both types of involvement are needed and can’t be done by same group S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

AWTT Flow Chart Data/Product for users Sponsorship of Users’ Needs User Needs Analysis Initial concept of use (ConUse) D2 User Needs Analysis (refined) ConUse (refined) D3 Initial ConUse approval AVR approvals or approval plans in place Initial approval of requirements Enter AMS Process, if needed D4 Final ConUse approval Final AVR approvals in place Final approval of requirements AMS Process, if needed, completed Operational Platforms Release product for operational use by selected users (AWTT Board decision) Data/Product for users Sponsorship of Users’ Needs R&D and Controlled Testing Experimental Application D1 D2 D3 D4 Assign new needs (ARS-20 coordinate ATS/AVR/NWS decision) Select/fund R&D projects to support needs (ARS-20 coordinate ATS/AVR/NWS decision) Release product for testing under FAA test plan (e.g., display on ADDS) (AWTT Board decision) ASG Decision S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt Optional Path

Contents of UNA & ConUse Identify users (decision makers) Document operational decisions requiring weather information Describe ideal information needed to support operational decisions Specify performance metrics (how good is good enough?) Identify needed Rule/guidance changes Describe needed user training Define needed access architecture (ConUse only) S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

Approaches to Solution Systemic: Develop a roadmap to address to show plan to reduce product proliferation and manage unintended regulatory impact Product Specific: Obtain more effective input from user experts on individual product design S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

Roadmap Shows migration path from existing products to new product suite: Identifies product mergers and replacements Done for each weather category and user class Identifies regulatory impacts & develop plan for rule/guidance change, domestic & international Identifies priorities for supporting research S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

Roadmap Production FAA/NWS draft Roadmap based on: Mission Needs Statements Current UNA & ConUse documents Current research plans AWTT Users Group review and comment Iterate as needed S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

Enhance Input from Expert User Teams for Product Design Document/validate results from ongoing expert user teams Document early in ConUse & update frequently Publish ConUse early & employ systematic review Enhance expert user teams Employ Users Needs Analyses before R&D Selectively add user teams during R&D & document results in ConUse for systematic review Enhance AWTT User Meetings for oversight Systematic web review of UNA/ConUse documents Double meeting frequency to quarterly? S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

Constraints User input processes must adhere to Federal Advisory Committee Act and Administrative Procedures Act Increased PBO emphasis on measured performance improvement Reduction in accidents Increased capacity & efficiency Limited time & travel resources for requirements processes, both sides S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

Summary To improve requirements, FAA will develop, with user input: A roadmap showing migration to fewer but better product suites with fewer unintended regulatory constraints Improved users technical input to product design. Both managed thru enhanced AWTT users meetings S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt
