Navigation Services Overview

1. Navigation Services Overview Eastern Service Area NAVAIDS Program Execution Meeting JC Johns Director Navigation Services

2. Navigation Services By Another Name Positioning, Navigation and Timing (PNT) Positioning, the ability to accurately and precisely determine one's location and orientation two dimensionally (or three dimensionally when required) referenced to a standard geodetic system (such as World Geodetic System 1984, or WGS84); Navigation, the ability to determine current and desired position (relative or absolute) and apply corrections to course, orientation, and speed to attain a desired position anywhere around the world, from sub-surface to surface and from surface to space; and Timing, the ability to acquire and maintain accurate and precise time from a standard (Coordinated Universal Time, or UTC), anywhere in the world and within user-defined timeliness parameters. Timing includes time transfer.

3. Efficient, Flexible Routing Vector Free - Streamlined Arrivals - Departures All Weather Approaches Navigation Services Vision • Provide safeandcost effective position, navigation, and timing services (PNT) to meet the operational needs of aviation customers.

4. FAA Satellite Navigation Program

5. Ground-Based Navigation Aides • Only a handful of ILS are being added (congressional) • Sustainment effort is minimal and focused on MK-1D and MK-1E systems • Long Term sustainment effort will be focused on Cat II/III runways • DME service continues well into the future • Sustainment effort robust, replacing obsolete systems • Establishing efforts ongoing in support of CFIT(CAST) • NextGen initiative to support enroute and terminal solutions Distance Measuring Equipment (Slant Range - UHF) Glideslope (Vertical Guidance - UHF Frequencies) • VOR drawdown has begun • Each legacy VOR that is eliminated reduces overall cost to FAA • Critical VOR’s will be maintained at certain waypoints and facilities for the foreseeable future Localizer (Lateral Guidance - VHF Frequencies) VHF Omnidirectional Range

6. Lighting Systems • Maintaining Safety Standards and Requirements • To help enable instrument approaches at airports • Types of Airport lighting currently being addressed • PAPI, VASI, MALSR, ALSF, REIL, Taxiway Indicators • New Initiatives • Reducing Life-Cycle Cost of Lighting Systems: • Maintenance costs • Energy consumption reduction • LED’s

7. Wide Area Augmentation System (WAAS) Architecture 38 Reference Stations 3 Master Stations 4 Ground Earth Stations 2 Geostationary Satellite Links 2 Operational Control Centers

8. WAAS Benefits • Serves all classes of aircraft during flight operations in all weather conditions at all locations throughout the National Airspace System (NAS) • Provides precise navigation and landing guidance to pilots at all airports, including thousands that have no ground-based navigation aids • Overcomes obstacles to ground-based systems, such as mountainous terrain • Reduces operating and maintenance costs associated with ground-based navigation aids • Makes more airspace usable to pilots, provides more direct en route paths, and provides new precision approach services to runway ends • Through international cooperation provides a global navigation system for all users • WAAS addresses the following performance gaps: • Lack of precise navigation capabilities that can handle the continuing growth in air traffic • Lack of stable vertical guidance in all weather conditions • Inconsistencies in global use of GPS and its augmentations • Aging of navigation systems that are expensive to maintain

9. Ground Based Augmentation System (GBAS) Capabilities • Represented in the US by Local Area Augmentation System (LAAS) • One LAAS covers multiple runway ends • LAAS eliminates ILS critical areas • Supports offset landing thresholds and flexible glide-path to mitigate wake turbulence • Contributing technology for high precision terminal area navigation services • Closely Spaced Parallel Approach • Simultaneous Independent Approach • Precise positioning for terminal area navigation RNAV and RNP • Benefits: • Replaces aging navigation systems that are expensive to maintain • Increases efficiency of arrival and departure operations and improves usage of runway capacity • Supports fuel efficiency and noise abatement initiatives • Improves access to airports during extremely low visibility operations

10. Automatic Dependent Surveillance (ADS-B)

11. Path to Performance-Based NAS • The Next Generation Air Transportation System (NextGen) Defines Capabilities Needed to Meet Demands For the 2025 Time-Frame • The Roadmap for Performance-Based Navigation Defines the Area Navigation (RNAV) and Required Navigation Performance (RNP) Goals

12.
