AdministrationFebruary 28, 2008

Peak Aircraft Traffic Over The US



Future Planning Assumptions• By 2025 , Aviation is Expected to Increase

By a Factor of 2.7

• The NAS Will Transition to Satellite Navigation Technology

– Provide Performance-Based Navigation Services to Enable RNAV & RNP

– Position Navigation Timing (PNT) is a critical enabler for NextGen

– New Navigation Services Must Be Cost-Beneficial

• Legacy Services With Negative Benefits/Cost Will Eventually Be Removed Cost

• Resources Will Be Limited



Global Navigation Satellite System (GNSS)



Global Positioning System (GPS)Space Segment• 24 Orbit Slots• 6 Orbital Planes• 4 Satellites Per Plane (Nominal)• 55 Degrees Inclination• Orbit at 10,800 Miles• Orbits Once Every 12 Hours

Control Segment• 5 GPS Monitor Sites• 13 NGA Monitor Sites• 2 Operational Control Centers

User Segment• Military & Civil Receivers• Precise Positioning Service (PPS)• Standard Positioning Service (SPS)

WAAS Procedures to be Published to All Instrument Runways in the NAS by 2018



Summary of RNAV(GPS) - Minima

LPV - Localizer Performance with Vertical

WAAS avionics minima

LNAV/VNAV – Lateral Navigation With Vertical

Baro-VNAV, or WAAS Avionics

LNAV - Lateral Navigation

Non-Precision Approach (NPA)



WAAS Avionics Status

• General Aviation– Garmin WAAS Receivers Sold ~26,000– Bendix-King Bringing Products to Market

• Business & Regional Aircraft FMS Avionics– Rockwell-Collins: Expecting CRJ/Canadair 604 STC

approval in FY‘08 – Canadian Marconi Corporation (CMC): Integrate WAAS

Into Honeywell Primus 2000 FMS by December 2008. – Universal Navigation Systems (UNS) Avionics: WAAS-

Enabled Capability in Dual Thread UNS-1 FMS TSO in 2007

• Air Carrier & Cargo Aircraft– Southwest Airlines

• Equipping 200 Boeing 737 with Rockwell Collins' GPS-4000S for Required Navigational Performance (RNP) operations

– Federal Express (FEDEX)• Equipping 253 Cessna Caravan Aircraft with Garmin GNS-

530W WAAS avionics and GMX-200 multi-function displays• Starting to equip 48 Q400s with Universal UNS-1F avionics

• Helicopter Aircraft Implementing WAAS



Preparing Airports for WAAS

Steps To Prepare Airport1. Review information on getting an instrument approach at:

http://avn.faa.gov/index.asp?xml=ifp/index

2. Contact Airport District Office to determine Infrastructure requirements/improvements

3. Contact the ADO or FPO to determine survey needs and/or check the status of FAA-sponsored surveys at:

[email protected].

• 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)



Local Area Augmentation System (LAAS)

• Precision Approach For CAT- I, II, III

• Multiple Runway Coverage At An Airport

• Terminal Area Procedures for Arrival and Departure



Current Activities

• Integrity Analysis and Prototype Development• LAAS System Design Approval (SDA) Process • LAAS Operational Implementation at Memphis Airport• International Cooperation and Development• CAT-III Research & Development Activities



Agana, Guam

Frankfurt, Germany

Rio De Janeiro, Brazil

Malaga, Spain

LAAS/GBAS International Efforts

Sydney, Australia

Bremen, Germany



Summary

• The FAA is Implementing Satellite Navigation Systems Needed to Support Performance Based Navigation and NextGen

• The WAAS Program Has Matured Through Development and is Rapidly Progressing Through Operational Implementation

• The First Certified LAAS is Expected In Late 2008

• Satellite Navigation is a Cornerstone of the Next Generation Air Transportation System (NextGen)
