Introduction2007 air traffic data link services

• North Atlantic Region benefits from data link
• In 2004, traffic levels exceeded pre2001 levels
• NAV CANADA has reduced communication costs to
  users by 50
• 55 of the fleet use either FMC WPR or FANS 1/A
  ADSC for automatic position reporting

PDC DATIS via ACARS
U.S. oceanicairspace boundary

• Pacific SubRegion benefits from data link
• Reduced separations to 50/50 NM and 30/30 NM
  (trials)
• User preferred routes and reroute (trials) for
  all city pairs in South Pacific
• Weather deviations
• Automatic position reporting
• 80 of the fleet in South Pacific use CPDLC and
  ADSC, based on FANS 1/A, 60 in the Central
  Pacific, and 30 on average in the entire Pacific

And then some

• What will we do with
• HF voice
• INMARSAT Aero Classic Satellite Service
• And what about
• Voice communications, e.g., INMARSAT, Iridium
• Data communications, e.g., HF Data Link, Iridium,
  Swift Broadband, Internet Protocol Suite (IPS)

• Review operational data and advise based on
  results
• Data link ? VHF, Satellite, HF data link
  performance
• Satellite voice ? Security procedures

8
Continued operational safety

• Fluctuations in performance levels for commercial
  satellite services
• Backups and redundancy
• Dissimilar technologies, e.g., Iridium, HF data
  link, INMARSAT, data/voice
• What are the performance criteria, what needs to
  be monitored, and what is the decision process
• What about predicted performance?

9
Standards guidance material

• ICAO completed standards and guidance material
  for RCP
• Provisions for RCP in Annex 6 and Annex 11
• Manual on RCP ? ICAO Doc 9869
• RTCA SC-189/EUROCAE WG-53 completed standards for
  data link services
• Continental Safety and Performance Standard
• Oceanic Safety and Performance Standard

10
Performance-based operations

• Balances capability performance of
• Communications, e.g., DCPC
• Navigation, e.g., RNAV/RNP
• Surveillance, e.g., ADS-C
• Air Traffic Management
• Builds on what we have to improve

11
Performance-based communications

• RCP type specifies communication transaction
  time, continuity, availability, integrity
• Other operational factors may be relevant, for
  example
• Messages or phraseology, transaction types, and
  intended use
• Interactive capability of voice communication
• Airground integration capability of data
  communication
• Performance monitoring and alerting
• Adapting the airspace to changes in performance
  level

12
Objectives and benefits

• Promotes a competitive market for aeronautical
  communication services enabling costeffective
  alternatives that meet business needs in a more
  timely manner
• Provides means to demonstrate communication
  performance using a variety of acceptable methods
  in lieu of time consuming data collection and
  empirical analyses
• Defines needed operations based on
  communication performance levels that are not yet
  obtainable with current technology
• Enables varying service levels in common airspace
  to a fleet of aircraft with varying communication
  capabilities and performances

13
Applicability

• When a change is implemented in air traffic
  management (ATM) and/or flight operations
• And the change is predicated on communication
  performance
• Safety management and monitoring

14
What it does

• Establishes operational criteria
• Determines capability and performance criteria
  based on intended operations in oceanic, en
  route, terminal, and airport domains
• Considers voice and data communications
• Considers global seamless operations
• Specifies RCP type and other relevant operational
  factors
• Not based on any particular technology

15
How it is used

• Performance-based criteria is used to
• Determine viability of a particular technology
• Qualify, certify, and approve various parts of an
  implementation
• Manage performance levels needed to provide a
  basic level of service and, for eligible
  operators, higher levels of service
• Real time monitoring and alerting (air and
  ground)
• Historical monitoring and evaluation
• Adapting the airspace based on the results of
  monitoring

16
Candidates for implementation

• Reduced separation minima, new procedures, or
  increasing airspace capacity that requires a
  communication capability and performance
• Operating in airspace with a basic level of
  service and, for eligible operators, with higher
  levels of service
• Provision and use of air traffic service using
  non-traditional technology or mixed technologies
• Communication capability installed on aircraft
  whose performance is suitable for use in some
  airspace, but not in others

17
PARC (Who - What)

• Performance-Based Operations Aviation Rulemaking
  Committee (PARC)
• Operates under the FAA Administrators legal
  authority in accordance with 49 USC 106(p)(5)
• Comprises members from the aviation community at
  large and FAA
• Provides recommendations to FAAs Senior
  Management for action implementation
• Effective in implementing RNAV/RNP

18
PARC Communications Working Group

• Roadmaps, etc.
• Build consensus among aviation stakeholders
• Communicate fundamental capabilities
• Assess benefit and investment
• Set metrics to measure success of FAA
  implementation programs

Roadmap for Performance-Based Communications
19
Outlook

• Complete industry-coordinated Roadmap for
  Performance-Based Communications by
  September 2007
• What are the applications for performance-based
  communications
• What standards are needed and schedule
• What is the strategy for aircraft type
  certification, operational approval, and
  implementation

20
Outlook

• Develop scenario outlines for implementation of
  RCP type, considering
• Voice and Data communications to increase
  capacity
• Oceanic and domestic (en route, terminal area,
  airport)
• Operating in airspace with a basic level of
  service and, for eligible operators, with higher
  levels of service
• Some existing communication capabilities and
  performance that are suitable only for basic
  level of service
• Performance monitoring, alerting, based on RCP
  type, and adaptation
