SmartPath® GBAS Value Summary
• Increased airport capacity: SmartPath unlocks capacity constraints
– Offers precision approach where ILS cannot due to geography
– Enables flexible approaches,(26), improved accuracy versus ILS
– Airport benefits from increased revenue (landings fees, concessions, etc.) and cost
avoidance (capacity increase w/o adding runways)
• Lower life-cycle cost: SmartPath is more cost efficient than ILS
– One SmartPath GBAS serves all runways, initial acquisition cost is lower
– Lower maintenance cost
– Lower flight inspection cost
• Safety: SmartPath improves safety
– Certification pedigree
– Signal stability (immune to signal bends inherent in ILS)
• Reduced noise/shorter routes: Variable glide slopes, RNAV/RNP to GLS finals
– Airlines benefit: fuel and emission savings, increased schedule flexibility, avoid noise
violations
– Airports benefit: increased capacity and schedule flexibility, improved community
relations

GLS Uses Existing Aircraft Architecture – Reduces Training
Costs & Maximizes Operational Benefits
• ILS look alike
– Glideslope
– Localizer
GLS – GPS Landing System
ILS – Instrument Landing System

CAT-I Certification
Certification Process
• System Design Approval (SDA) – Manufacturer
– Ground station system design meets
requirements
– Developed to appropriate design assurance
levels
• Facility Approval – Owner/ANSP/Airport
– Ground station installed
– Flight test completed, approach flyability,
VDB coverage
• VDB = VHF Data Broadcast (i.e. ground-toairborne signal in space)
– Maintenance technicians trained, certified
• ANSP = Air Navigation Service Provider (e.g.
FAA in the U.S.)
Operational Approvals
•First To Certify:
• Bremen Germany; German Type Approval
received 30 Nov
•1st International Certification of
SmartPath
•Newark New Jersey: 28 Sept 2012
• Houston Intercontinental;:April 2013
•Sydney Australia Q2 2013
• Malaga Spain Q3 2013
• Brazil Q4 2013
• Service Approval – Operator/Airline
– Aircraft equipped
– Pilot, crews trained

Single RPAT Concept
RPAT: 2.5 Degree on 30L with 3.2 on North. FAFs displaced 3.8nm
1. Both turns are 2.0nm radii
2. Both FAFs are 3.99nm apart
3. The north runway assumes current ILS
operations of 3 degrees

Dual RPAT: 2.5 on South, and 3.2 on North.
FAFs laterally offset and 6.4nm apart.
Note the altitude differences on the waypoints
below based on the associated GPS

SmartPath® Delay Savings
• Off-Load (6) Aircraft to Secondary Runway/Hr
• 55 minutes Delay vs. 315 minutes Delay
• Arrivals – compacted demand (even small queues)
generate significant cumulative delays and increased
operating costs for arriving aircraft – $65 per min
• A single runway, AAR of 30, demand of 30, will
generate 200 – 400 delay minutes per hour ($26K ops
cost) -- US also considers Passenger Value of Time
(PVT) $35 p/hr per passenger for investment
decisions
• PVT is equal to or greater than ops cost
• Moving a small number of aircraft out of the queue to
an offload runway reduces delay significantly
