  1. NACES ADVANCED ELECTRONIC SEQUENCER PROGRAMFUTURE ADVANCED SEQUENCER TECHNOLOGY (FAST) AIRCREW SYSTEMS ILSMT BRIEFING

  2. FAST PROGRAM BACKGROUND • 99 AFFORDABLE READINESS INITIATIVE SUBMITTED TO REDUCE COST OF CURRENT NACES SEQUENCER BY 50 PERCENT USING COMMERCIAL OFF THE SHELF COMPONENTS. • NACES P3I PHASE II PROGRAM TO DEVELOP ADVANCED CAPABILITY TECHNOLOGY SEQUENCER CONCEPT ALSO USING COMMERCIAL OFF-THE-SHELF (COTS) COMPONENTS FOR REDUCED COST. • DECEMBER 98 MERGER OF BOTH PROGRAMS TO DESIGN, MANUFACTURE AND QUALIFY AN ADVANCED ELECTRONIC SEQUENCER WITH COTS COMPONENTS FOR NACES.

  3. FAST PROGRAM DESCRIPTION • PROGRAM • QUALIFY ADVANCED SEQUENCER AND APPROVE ECP TO MEET NACES LOT 16 PRODUCTION INSTALLATION • DEVELOP OBSOLESENCE PLAN TO CONTROL COTS COMPONENTS • 10 YEAR WARRANTY FOR FAST CONCURRENT WITH PRODUCTION • NAVICP PBL TO SUPPORT BASELINE AND FAST IN THE FLEET • TECHNICAL • EVENT TIMING NOW BASED ON AIRSPEED, ALTITUDE AND NOW ALSO RESULTANT DECELERATION. LIMITS PARACHUTE OPENING LOADS. GOOD FOR EXPANDED AIRCREW POPULATION • CONTINUOUS SENSING FOR IMPROVED FAULT TOLERANCE AND OPTIMIZED PERFORMANCE • NEW REDUCED PARACHUTE DEPLOYMENT TIMING “BACK OF BOAT” MODE • IMPROVED DATA RECORDING CAPABILITY • TEMPERATURE COMPENSATION OF SENSORS • SURFACE MOUNT TECHNOLOGY • ADA95 LANGUAGE • EXPANSION CAPABILITY TO INTERFACE WITH EMERGING TECHNOLOGIES
