NAV03.2 — RNP 1 in TMA Operations

Performance-based navigation distinguishes between RNAV and RNP Specifications, both of which rely on area navigation techniques which allow aircraft to operate on any desired flight path within the coverage of station-referenced navigation aids or within the limits of the capability of self-contained aids, or a combination of these. An RNP 1 specification allows an aircraft to fly a specific path between two 3D-defined points in space; to this end, the RNP 1 specification requires a lateral performance accuracy of +/- 1NM 95% of the flight time, on-board performance monitoring, alerting capability and high integrity navigation databases.

Where ANS providers have established SID or STAR and where higher performance requirements than those of RNAV 1 are required in order to maintain air traffic capacity and safety in environments with high traffic density, traffic complexity or terrain features, they shall implement those routes in accordance with the requirements of the RNP 1 specification, including one or more of the following additional navigation functionalities:

(a) operations along a vertical path and between two fixes and with the use of:
(i) an ‘AT’ altitude constraint;
(ii) an ‘AT or ABOVE’ altitude constraint;
(iii) an ‘AT or BELOW’ altitude constraint;
(iv) a ‘WINDOW’ constraint;

(b) the radius to fix (RF) leg.

Establishment of RNP1 SID or STAR is not imposed as obligatory requirement by the PBN Regulation (EU) 2018/1048 (business decision on having SID or STAR is up to an individual stakeholder). However, the PBN regulation does prescribe obligatory set of specifications to be complied with, where a stakeholder had decided to establish SID or STAR. Individual ANSPs, airports and aircraft operators outside of the Applicability Area 1 may implement this functionality on a voluntary basis. In this case they will need to evaluate the business case for the implementation of RNP 1 procedures according to local circumstances.

NOTE 1: System improvements for controller support tools which may be required are covered by other Implementation Objectives like ATC12.1 (MTCD, conflict resolution support info and MONA), ATC02.9 (STCA) and ATC02.8 (APW).

NOTE FOR MILITARY AUTHORITIES: It is the responsibility of each military authority to review this Objective IN ITS ENTIRETY and address each of the SLoAs that the military authority considers RELEVANT for itself. This has to be done on top and above of the review of "MIL" SLoAs which identify actions EXCLUSIVE to military authorities.

Expected Performance Benefits

Increased situational awareness and indirect benefit to both ATC and pilot through reduction of workload during RNP operations.
Increased capacity through efficient and improved systemisation of SID/STARs based on RNP 1, particularly on curved paths using Radius to Fix functionality.
Operational efficiency
Reduction in fuel burn and potential to reduce track miles through optimised TMA procedures using the Radius to Fix Functionality.
Cost efficiency
Emissions and noise nuisance reduced by use of optimal flight procedures and routings.
