Ground-Based Navigation AidesGround-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

•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

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
• 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

Airline Commitments• Aircraft with GBAS capability today: 53(Continental, Qantas, Air Berlin, TuiFly,
Sonair, Air Vanatu, FedEx)• 60+ Airlines have ordered GBAS capable Boeing/Airbus aircraft• Boeing orders estimated at 1000+ airplanes (B787, B747-8, B737NG)
• GBAS standard on B787 and B 747-8
B 787 orders A 380 orders with GBAS option
895 orders by 57 customers
