Introduction toRequired Communication Performance (RCP) andRequired Surveillance Performance (RSP) SOCM/2 Christine Falk 8-10 February 2012
Introduction • Guidance & Directives 2. Required Communication Performance - RCP 400 - RCP 240 3. Required Surveillance Performance - RSP 400 - RSP 180
Guidance PublicationsFor RCP and RSP • ICAO Doc 4444 and ICAO Annexes 2,6,10, and 11 • Global Operational Data Link Document (GOLD), 14 June 2010 -- Derived from these documents • RTCA DO-306 Safety and Performance Standard for Air Traffic Data Link Services in Oceanic and Remote Airspace (Oceanic SPR Standard), 11 October 2007 • ICAO Document 9869, Manual on Required Communication Performance, First Edition, 2008
Authorization Requirement ICAO Annex 6, Chapter 7 7.1.3 For flights in defined portions of airspace or on routes where an RCP type has been prescribed, an aeroplane shall, in addition to the requirements specified in 7.1.1: a) be provided with communication equipment which will enable it to operate in accordance with the prescribed RCP type(s); and b) be authorized by the State of the Operator for operations in such airspace.
Performance Based Operations RNP RCP Balances capability & performance of: N C (RCP) • Communications ATM (RNP) • Navigation (RSP) • Surveillance S • Air Traffic Management (ATM) RSP RNP – required navigation performance RCP – required communication performance RSP – required surveillance performance
Required Communication Performance A statement of communication performance necessary for a particular operation or service. • Operationally derived and not based on any specific techniques, technologies and/or architecture. • Defined for an operational communication transaction (two-way) • Includes both human and technical elements • Applies to both voice and data link communications
RCP specification is… • A label that defines a performance standard for operational communication transactions (e.g. RCP 400) • Provides allocations to the air traffic service provider (ATSP), communication service provider (CSP), aircraft operator and aircraft system • Denotes operational values for: • Communication transaction time • RCP Continuity • RCP Availability • RCP Integrity
RCP definitions Operational communication transaction - The process a human uses to send an instruction, a clearance, flight information and/or a request. The process is completed when that human is confident that the transaction is complete. RCP Communication Transaction Time - The maximum time for the completion of the transaction after which the initiator should revert to an alternative procedure. RCP Continuity- Probability that a transaction can be completed within the communication transaction time given that the service was available at the start of the transaction. - Either expiration time (ET) or nominal time (TT) of 95% RCP Availability - Probability that a transaction can be initiated when needed. RCP Integrity- Probability that a transaction is completed with no undetected errors.

Required Surveillance Performance - RSP • Defines high-level surveillance system performance requirements. • Operationally derived and not based on any specific techniques, technologies and/or architecture. • Includes both ground and airborne systems. • Supports a particular ATM application (e.g. reduced separation)
RSP specification is… A label (e.g. type 400) that represents the values assigned to surveillance performance parameters for: • Surveillance data transit time • RSP Continuity • RSP Availability • RSP Integrity Provides allocations to the air traffic service provider, communication service provider, aircraft operator and aircraft system
RSPdefinitions Surveillance data transit time-The required time for surveillance data delivery. RSP Continuity-The required probability that surveillance data can be delivered within the delivery time parameter given that the service was available at the start of delivery. - Either Overdue Time (OT) or nominal delivery time (DT) of 95% RSP Availability -The required probability that surveillance data can be provided when needed. RSP Integrity-The required probability that surveillance data is delivered with no undetected error.
