APV Procedures Design Workshop

Following the successful workshop held at Sofia last 22nd May, the SHERPA consortium is pleased to announce that the second SHERPA project Workshop will take place in Tallinn (Estonia) on the 13th September 2012, from approximately 9h to 17h.

This second workshop will be held at the Estonian Air Navigation Services (EANS) premises located close to Tallinn airport.

The main objective is to provide initial guidance to all the attendees as part of the national Stakeholder teams involved in APV implementation activities in the following areas:

  • APV/LPV concept;
  • ICAO PANS-OPS LPV affected chapters: design criteria, database coding issues, obstacle evaluation and protection areas, data accuracy, charting, Channel Number assignation...;
  • Lessons learnt from previous projects, regarding limitations on database coding (i.e. discrepancies between PANS-OPS and ARINC 424 database standard);
  • Specific issues to be addressed regarding data quality assurance;
  • Overview of LPV procedure validation methodology;

This second workshop coincides with the start of SHERPA's WP2000, where participants will perform initial activities required to publish LPV procedures at their selected scenario.


SHERPA is a collaborative project funded by the European Commission 7th Framework Programme through the European GNSS Agency (GSA), that proposes, aligned with ICAO and Eurocontrol recommendations, an approach in support to the implementation of APV procedures, by undertaking pre-operational actions at local Stakeholders level in a coordinated manner, and to map the implementation of EGNOS into the States PBN strategy.
