Implementation Methodology

One of the main objectives of P-RNAV introduction is to achieve an ECAC wide consistent design and operation of RNAV in Terminal Airspace. To this end, Terminal Airspace procedures that require P-RNAV approval will have been designed by the Air Navigation Service providers according to a common methodology. This common methodology is outlined below. It also includes the reference documentation that is applied in the various design and implementation steps.

		Consider Benefits of Terminal Airspace optimisation using P-RNAV e.g. ATC Workload reduction, fuel reduction, ACFT equipage cost (Cost benefit analysis) Viability of phased implementation to ease transition fromoperational perspective Associated ATC Procedures required to reap benefits. Impact of P-RNAV / Conventional Nav. Mix on ATC and Operators (e.g. Effects on operators not P-RNAV approved) Nav infrastructure requirements & associated RNAV flight checking PANS-OPS Procedure design: limitations & opportunities (e.g. Training of designers) Decision & Action - Time scales for all actions associated with P-RNAV implementation Notification of intent by operators to implement P-RNAV (These items may only be of relevance to States regularizing their RNAV applications by implementing P-RNAV) Guidelines & Reference Material
		Evaluation Phase (Qualitative Analysis) Proposed P-RNAV route placement [subject to NAV infrastructure availability & coverage] Consider P-RNAV procedure design (PANS-OPS) Re-design of Terminal Airspace volume, if required Re-design of ATC sectorisation, if required Quantitative Analysis ATM safety case to assess acceptability of proposed routeing and airspace changes; incl FTS/RTS as required. If acceptable, continue with PANS-OPS procedure design for P-RNAV certified aircraft Guidelines & Reference Material
		APPLICATION OF AVAILABLE STANDARDS AND GUIDANCE ON Minimumcomplexity Way-point naming Validation of procedures (e.g. flight checking & flyability for all ACFT. types) 3.a ENSURE AVAILABILITY OF REQUIRED NAVAIDS Determine current P-RNAV coverage Establish means of flight checking 3.b ENSURE ACCURACY AND INTEGRITY OF ASSOCIATED CO-O0RDINATE DATA Verify WGS/84 compliance and associated AIS processes 3.c P-RNAV PROCEDURE PUBLICATION AIP description incl. coding advice, charting, advice on when to engage RNAV/FMS (e.g. LNAV); non P-RNAV procedures Application of available standards and guidance Guidelines & Reference Material
		Introduce P-RNAV ATC procedures as per ICAO (e.g. use of waypoints for tactical routeings, aircraft RNAV contingencies) supplemented by Local procedures, as required Local procedures for handling non-approved Aircraft Publication of ATC procedures in local operations manuals and related documents Guidelines & Reference Material
		Adapt local FDPS for processing of aircraft PRNAV equipment info; Implement capability for automatic and systematic display of individual aircraft RNAV equipment information to ATC; (Radar or Flight Strip) Guidelines & Reference Material
		Schedule and perform Local ATC training, taking into account Local real-time simulations Guidelines & Reference Material
		As required by National Authority Documentation of processes and applied standards Address local peculiarities & local risk mitigation where required Detailed requirements dependent on requirements set by state authority taking into account material agreed through EUROCONTROL safety regulation material Guidelines & Reference Material
