ADSB An Industry Perspective

1
ADS-B An Industry Perspective

• New Technologies Workshop
• Washington, DC
• January 10, 2007

2
ADS-BAutomatic Dependent Surveillance - Broadcast

• Why?
• Why so soon?
• Why does the FAA support ADS-B?
• Why might the aviation community support ADS-B?
• Why is the FAA developing a Proposed Rule for
  ADS-B?

3
ADS-B Why?

• Reduce Surveillance Costs for FAA
• Surveillance applied in locations where radar
  does not exist today.
• Gulf of Mexico
• Mountainous Airports
• Superior update rate
• Facilitates reduced separation standards
• Facilitates future capacity enhancements
• Much of the JPDO CONOPS hinges around ADS-B type
  applications.

4
ADS-B Why so soon?

• Ground Based infrastructure replenishment
  decisions in the 2020 timeframe drive commitments
  today.
• Retrofit cycles
• GA (10 year equipage cycle)
• Commercial Aviation ( 7 year cycle)
• Assumes up to 10 years of prior development to
  field the avionics
• Question might be why so long?

5
ADS-BWhy does the FAA support ADS-B?

• Transition from ground based surveillance to
  satellite centric operations
• Divestment
• Strategic Investment decision with positive long
  term cost / benefit
• Support aviation community demand
• Enhances safety and capacity

6
ADS-BWhy might the aviation community support
ADS-B?

• General Aviation
• Flight Information Service Broadcast (FIS-B)
• Traffic Information System - Broadcast (TIS-B)
• Supports reduced costs imposed by FAA
• Situational Awareness and Safety enhancements
  akin to current Capstone program in Alaska

7
ADS-BWhy might the aviation community support
ADS-B?

• Commercial Aviation
• Supports future reductions in separation
  standards from current standards to meet
  2020-2025 demand.
• 5 mile enroute / 3 mile terminal separation
  standards are unlikely to meet this demand
• Supports future capacity enhancements
• With navigation enhancements, will benefit
  arrival and departure rates
• Establishes the foundation for future cockpit
  safety and situational applications
• VFR like separations in some cases
• Surface surveillance applications

8
ADS-BWhy is the aviation community working
through RTCA to develop recommendations for a
Proposed Rule associated with ADS-B?

• Establishes a collaborative model where FAA and
  aviation community develop the future in a
  collaborative manner
• Road to NexGen passes through ADS-B
• Lays the foundation for future system
  enhancements
• Addresses many of the transition issues of
  moving to a aircraft centric NAS

9
Challenges

• The Transition Plan
• The Equipage Curves
• The Cost Benefit story
• The Consequences of Failure

10
Transition Plan

• The Proposed Rule
• Accomplished in the 2007 2010 timeframe
• The Implementation Begins
• Gulf of Mexico and Eastern Seaboard
• 2010 timeframe
• The ADS-B Infrastructure
• Deployment complete in 2015 timeframe
• Benefit accrues to early equippers
• The Effectivity Date (2020 timeframe)
• Near 100 equipage is required
• Ground Based Radar removals begin

11
Equipage Curves

• G A uses a 10 year equipage cycle
• GPS or GPS / WAAS requirements
• Challenges relative to backup scenario where
  surveillance source (GPS) is not available
• Regional Community uses 7 year retrofit
• Lack of Inertial introduces GPS backup concerns
• Augmentation may be required
• Commercial Carriers use 7 year retrofit cycle
• Augmentation may be required

12
Cost Benefit story

• Business Case is annualized through 2035
• Pay back to FAA and to Aviation Community is not
  immediate
• Aviation Community ADS-B business assessment is
  challenging
• Lays the groundwork for future benefit
• Establishes the foundation for enhanced
  Surveillance and Navigation

13
Cost Benefit story

• Fundamental Issues/Questions are
• Do you believe in the projections of at least
  double current capacity in 2020 -2025?
• Do you believe the transition ever goes away?
• Do you believe the service provider or the
  aviation community can make fundamental, earth
  changing decisions in isolation?

14
Consequences of Failure

• Do you believe in the projections of at least
  double current capacity in 2020 -2025?
• 100 seater projections
• 13000 today
• 27000 by 2025
• Do you believe the transition ever goes away?
• Plans and Vision are easy
• Transitions are Hard
• Do you believe the service provider or the
  aviation community can make fundamental, earth
  changing decisions in isolation?
• JPDO vision of 2025
• Were having difficulty in delivering ADS-B out
  by 2020

15
Summary

• One thing for sure, we need to move in this
  direction over time.
• Dont want to have to re-equip again before 2025.
• Retrofits or deliveries accomplished today need
  to support 2025 applications
• Dont want to change the aircraft architecture
• Dont want throw away equipment
