FAA Satellite Navigation – Status Briefing 13 Federal Aviation Administration January 5, 2007 WAAS Avionics Avionics –Garmin GNS-480/CNX-80 – Available Now Estimated 4,000 units sold (as of late 2006) –Garmin 400/500 Series Upgrade – Available January 2007 Of the 70,000 units sold, roughly 18,000 have pre-paid for the upgrade (as of late 2006) –Rockwell Collins unit supporting high-end FMS users (initial delivery to FAA for approval) - Expected March 2008 –Rockwell Collins WAAS LPV Upgrade for Challenger 604 (FAA flight inspection aircraft) - Scheduled for August 2007 –Chelton, CMC, Universal, and Thales – Expected availability 2007/2008

FAA Satellite Navigation – Status Briefing 14 Federal Aviation Administration January 5, 2007 Preparing Airports for WAAS WAAS Provides a Space-Based ILS-like Approach –No ground navigation hardware required –WAAS uses the same ILS obstacle evaluation area and procedure criteria * Airport Infrastructure Needed –Paved runways over 3200 ft. long by 60 ft. wide –Non-precision runway markings (or better) –Runway safety zone Airport Infrastructure Recommended to Obtain the lowest possible minima – Parallel taxiway (reduces decision height, but not mandatory) – Medium Intensity Runway Lights (reduces visibility and provides for night operations) Steps To Prepare Airport 1)Review information on getting an instrument approach at: 2)Contact Airport District Office to determine Infrastructure requirements/improvements 3)Determine if required level of airport survey exists, is scheduled, or will be acquired. * The same terrain issues that can prevent an ILS approach also pertain to LPVs.

FAA Satellite Navigation – Status Briefing 15 Federal Aviation Administration January 5, 2007 Local Area Augmentation System (LAAS)

FAA Satellite Navigation – Status Briefing 16 Federal Aviation Administration January 5, 2007 LAAS Benefits Precision Approach Service - CAT I/II/III One LAAS Serves All Runway Ends Potential for Reduced Facility Costs Guided Missed Approaches Provides Guidance for Complex Approaches Siting Flexibility allows service where ILS Can’t be installed May eliminate some ILS Critical Areas Tighter Spacing Due to More Accurate Navigation Parallel Simultaneous Instrument Approach Procedures

FAA Satellite Navigation – Status Briefing 17 Federal Aviation Administration January 5, 2007 Multiple Approach Capability of LAAS 70,000 square mile service volume could include other nearby airports Similar set of reciprocal way-points can define missed-approach, go-around procedures, SIDs and STARs VDB transmission include Differential GPS corrections Final approach segment (FAS) Way-point data listing blocks Ground station and approach ID Omni-directional VDB Radiates out to 150 miles (line of site) Pilot selects one of several “approved” approaches Control codes select VHF frequency and approach listing blocks of way-points LAAS GPS RXVHF TX Angled Approach Straight Approach Sectored Approach Parallel Approach Curved Approach
