ATM – More Dependency on Comm. and Surv.

A Performance Based Approach

• Doc 9883 Manual on Global Performance of the Air Navigation System– Notion of a performance based air navigation system emanated from

industry practices that have evolved for many years outside of aviation.– Based on following principles:

• Strong focus on desired/required results through adoption of performance objectives and targets

• Informed decision making, driven by the desired/required results; and• Reliance on facts and data for decision making.

– Assessment is periodically checked through performance review, which requires adequate performance measurement and data collection capabilities.

– Performance based approach is a pragmatic tool in• Planning changes• Developing changes• Optimising the System (Continuous Performance Improvement)

Performance Based NavigationPerformance Based Surveillance

PBN – current definition Annex 6 & 11

• Performance-based navigation (PBN).– Area navigation based on performance requirements

for aircraft operating along an ATS route, on an instrument approach procedure or in a designated airspace.

Note.— Performance requirements are expressed in navigation specifications (RNAV specification, RNP specification) in terms of accuracy, integrity, continuity, availability and functionality needed for the proposed operation in the context of a particular airspace concept.

PBC - ICAO OPLINKP amend Annex 6, 11?

• Performance-based communication (PBC). – ATS communication services and capability based on

performance requirements for aircraft operating along an ATS route, on an instrument approach procedure or in a designated airspace.

Note.— Communication performance requirements are allocated to system components in an RCP specification in terms of communication transaction time, continuity, availability, integrity, safety and functionality needed for the proposed operation in the context of a particular airspace

PBS - ICAO OPLINKP amend Annex 6,11?

• Performance-based surveillance (PBS). – ATS surveillance services and capability based on

performance requirements for aircraft operating along an ATS route, on an instrument approach procedure or in a designated airspace.

Note.— Surveillance performance requirements are allocated to system components in an RSP specification in terms of surveillance data delivery time, continuity, availability, integrity, accuracy of the surveillance data, safety and functionality needed for the proposed operation in the context of a particular airspace concept.

RNP - ICAO

• Navigation specification. A set of aircraft and flight crew requirements needed to support performance-based navigation operations within a defined airspace. There are two kinds of navigation specifications:– Required navigation performance (RNP) specification. A

navigation specification based on area navigation that includes the requirement for performance monitoring and alerting, designated by the prefix RNP, e.g. RNP 4, RNP APCH.

– Area navigation (RNAV) specification. A navigation specification based on area navigation that does not include the requirement for performance monitoring and alerting, designated by the prefix RNAV, e.g. RNAV 5, RNAV 1.

RCP - ICAO OPLINKP amend Annex 6, 11?

• Required communication performance (RCP) specification. – A set of requirements for air traffic service provision, aircraft

capability, and operations needed to support performance-based communication within a defined airspace.

Note: The term RCP, has been revised to align the concept of PBC with the concept of PBN. The term RCP is now used in the context of a specification that is applicable to the prescription of airspace requirements, qualification of ATS provision, aircraft capability, and operational use, including post-implementation monitoring (e.g. RCP 240 refers to the criteria for various components of the operational system to ensure an acceptable intervention capability for the controller is maintained).

RSP - ICAO OPLINKP amend Annex 6, 11?

• Required surveillance performance (RSP) specification. – A set of requirements for air traffic service provision,

aircraft capability, and operations needed to support performance-based surveillance within a defined airspace.

Note: The term RSP is used in the context of a specification that is applicable to the prescription of airspace requirements, qualification of ATS provision, aircraft capability, and operational use, including post-implementation monitoring (e.g. RSP 180 refers to the criteria for various components of the operational system to ensure an acceptable surveillance capability for the controller is maintained.

PBCS - RSP/RCP – ICAO FPL

• Currently, there is potential for an ATSP to misapply Air Traffic Services to an operator or aircraft type because no specific RCP or RSP definition is available in the FPL.

• Specific RCP/RSP definition is needed by ground system automation to enable reliable application of Air Traffic Services to suitably equipped aircraft that meet RCP/RSP specifications.

PBCS - RSP/RCP – ICAO FPL

• ICAO Flight Plan makes provision for RCP allocation in Item 10 with reserved designators. •Asia/Pac ICAO 2012 guidance specifically states that ATSP should process reserved RCP designators without error.• No similar provision with reserved designators was made for RSP allocation in Item 10 but does make mention of use of SUR/ in Item 18.

RSP/RCP – OPLINKP amend PANS-ATM Doc4444?

• Item 10a

Note 7.— Guidance material on the application of performance-based communication, which prescribes RCP to an air traffic service in a specific area, is contained in the Performance-Based Communication and Surveillance (PBCS) Manual (Doc 9869).

• Item 10b If the descriptor D1 is used, the performance-based surveillance level that can be met are specified in Item 18 following the indicator SUR/. Guidance material on the application of performance-based surveillance, which prescribes RSP to an air traffic service in a specific area, is contained in the Performance-Based Communication and Surveillance (PBCS) Manual (Doc 9869).

P1 RCP 400 (See Note 7)P2 RCP 240 (See Note 7)P3 RCP 150 (See Note 7)P4–P9 Reserved for RCP (See Note 7)

RSP/RCP – tactical indication in aircraft

• Aircraft provides the flight crew with alerts in case of equipment/capability failures, e.g.– Communication Means failure (e.g. SATCOM FAULT)– Definitive connectivity loss (e.g. VHF3 DATALINK FAULT)– Failure of ATC Data Link (e.g. ATC DATA LINK FAULT)

BUT• There is no RCP/RSP indication directly displayed to the flight

crew.

Note: Appropriate procedures (refer to GOLD) and associated training is required to ensure failure notifications to ATSP.

RSP/RCP – tactical indication to controller

• ATM ground system automation provides the controller with alerts in case of equipment/capability failures, e.g.– Communication failure. (e.g. ACARS FAULT)– CPDLC transaction timeouts. (e.g. NO RESPONSE RECEIVED)– ADS-C periodic reports overdue.

Note: If ground system provides indication to controller for action then controller can assess suitability of communications and surveillance for continued application of ATS service based on workload

BUT• There is no real time monitor of actual performance to indicate

“RCP/RSP unable” directly to the controller.Note: Appropriate procedures (refer to GOLD) and associated training is required for equipment/capability failures e.g. aircraft SATCOM failure?

PBCS – an introductory history (1)

• In 1991, the 10th ANC endorse the Future Air Navigation System concept. – This becomes known as the communications, navigation, surveillance/air

traffic management (CNS/ATM) systems concept.

• In 1996, at the 4th meeting of the Aeronautical Mobile Communications Panel (AMCP/4) recognises the absence of objective criteria to evaluate communications performance.

• In 2000 AMCP is renamed the Operational Data Link Panel (OPLINKP)

• In 1997, the Air Navigation Commission tasks OPLINKP to develop the concept of Required Communications Performance (RCP).

• In 2001, OPLINKP completed a concept of RCP and the Air Navigation Commission solicit State comment.

• In 2002, OPLINKP were tasked to develop a manual on RCP and as necessary develop SARP’s and procedures relating to the use of RCP in ATS.

PBCS – an introductory history (2)

• In 2003, the 11th ANC endorse recommendations to :– Confirm development of RCP– Investigate further areas including:

• Relationship of RCP to separation studies and interoperability• RCP Types and Allocations• Safety performance monitoring

• In 2007, Annex 6 - Operation of Aircraft, – Amended to introduce concept of RCP in the provision of ATS.

• In 2007, Annex 11 – Air Traffic Services and Doc 4444 PANS - ATM, – Amended to introduce definitions and associated procedures for RCP.

PBCS – an introductory history (3)

• In 2007, RTCA DO-306/EUROCAE ED-122 Safety and Performance Standard for Air Traffic Data Link Services in Oceanic and Remote Airspace (Oceanic SPR Standard) is published.– Provides operational, safety, and performance requirements for data link

services that support specific ATS functions in oceanic and remote airspace.

– Specifically provides RCP/RSP allocations for reduced separation standards

• In 2008, ICAO Doc 9869 Manual on Required Communications Performance is published.

• In 2010, ICAO Global Operational Data Link Document (GOLD) is published.– Appendix B – RCP Specifications– Appendix C - RSP Specifications– Appendix D – Post Implementation Monitoring and Corrective Actions

PBCS – an introductory history (3)

• In 2011/12, GOLD Edition 2 is developed with planned completion April 2013.– The GOLD, First Edition, Appendix C, refers to “surveillance performance

specifications.” The GOLD, Second Edition, will refer specifically to “RSP specifications.”

• In 2012/2013, OPLINKP develop proposals to:– Rename ICAO Doc 9869 “Manual on Required Communications

Performance” to “Performance Based Communications and Surveillance (PBCS) Manual”.

– Move guidance material from GOLD Edition 2 Appendix B – RCP Specifications, Appendix C – RSP Specifications, and Appendix D – Post Implementation Monitoring and Corrective Action into PBCS Manual.

– Amend Annex 6 Part I and Annex 11 to include standards associated with PBCS similar to PBN and refer to guidance material in Doc 9869 PBCS Manual.

RCP – Required Communications Performance

• RCP concept seeks to manage the performance of communications supporting evolving ATM concepts and emerging technologies. This is achieved by:– Determining an RCP type for the communications

capabilities supporting an ATM function; then– Prescribing the RCP type(s) related to the

communications system(s) supporting the ATM functions within that airspace; and

– Complying with the prescribed RCP type(s) through initial qualification, operational assessments, and post implementation monitoring/analysis/corrective action of the communications systems.

RSP – Required Surveillance Performance

• RSP concept seeks to manage the performance of surveillance supporting evolving ATM concepts and emerging technologies. This is achieved by:– Determining an RSP type for the surveillance

capabilities supporting an ATM function; then– Prescribing the RSP type(s) related to the surveillance

system(s) supporting the ATM functions within that airspace; and

– Complying with the prescribed RSP type(s) through initial qualification, operational assessments, and post implementation monitoring/analysis/corrective action of the surveillance systems.

FANS1/A - A Performance Based System?

PBCS - Continuous performance improvement

Enabling Benefits with PBCS

• Operational improvements (e.g. 30/30NM and 50NM Long) are predicated on certain communications (e.g. CPDLC at RCP240), surveillance (e.g. ADS-C at RSP180), and navigation requirements (e.g. PBN RNP4).

• We have an obligation to ensure that aircraft and operators are meeting these requirements.

• We have PBN that prescribes navigation specifications (e.g. RNP4 and RNP10) for 30/30NM and 50NM long.

• We need to implement PBCS and prescribe appropriate RCP and RSP specifications for the current 30/30NM and 50NM long separation and other functions predicated on communication and surveillance performance.

PBCS – Enabling Benefits with PBCS

• In summary, the performance-based approach is seen as a means to:– expedite and maximize operational benefits gained from

an existing fleet of data link capable aircraft– to expand the provision and use of data link

capabilities, where beneficial,– ensure global harmonization and operational

seamlessness of data link implementations.– take into account the overall operational capability and

performance needed for the intended operations.
