The European Commission Implementing Regulation (EU 2018/1048) stipulates that RNP approaches with vertical guidance have to be implemented at all instrument runway ends.
Approach procedures to lateral navigation (LNAV), lateral/vertical navigation (LNAV/VNAV) and lateral precision with vertical guidance approach (LPV) minima are to be implemented by:
- December 2020 on runways currently served only by non-precision approaches; and
- January 2024 on runways currently served by precision approaches.
EUROCONTROL supports the implementation of these procedures, bringing stakeholders together through the RNP implementation Support Group (RAiSG) to share best practices and lessons learned. Documentation associated with this group is available on the EUROCONTROL’s working group RAISG Onesky Teams (accessible only to registered users).
A unique number, the SBAS channel, is required for RNP approaches to LPV or LP minima. EUROCONTROL used to be the focal point in Europe for distributing and managing the SBAS channel numbers. This function was taken over by ICAO in 2019 when a unique world-wide allocation mechanism was put in place.
- the PBN map tool to illustrate the status and plans for implementing RNP approaches in the European Civil Aviation Conference area;
- an FAS DB tool that that computes the relevant cyclic redundancy check (CRC) remainder and generates an electronic file as well as a text description to support LPV procedure publication. It generates the final approach segment (FAS) data block which is required for all SBAS-based approaches.
