Navigation Services Vision
  • Provide safeandcost effective position, navigation, and timing services (PNT) to meet the operational needs of aviation customers.
slide4

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 VORs will be maintained at certain waypoints and facilities for the foreseeable future

Localizer

(Lateral Guidance - VHF Frequencies)

VHF Omnidirectional Range

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 Initiative
    • Reducing Life-Cycle Cost of

Lighting Systems:

      • Maintenance costs
    • Energy consumption reduction
      • LEDs

waas benefits
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
ground based augmentation system gbas capabilities
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
gbas gbas prototypes and scat 1 installations
GBAS, GBAS Prototypes, and SCAT-1 Installations

Installed

  • Multiple companies researching/developing versions of GBAS
    • USA – Honeywell / Raytheon (JPALS) - France - Thales
    • Russia - NPPF Spectr - Denmark – GM Merc/Lens,
    • Japan – JCAB/ENRI - Korea - KARA,

Planned
