2024 AGENDA

The Minimum Operational Network (MON) is aimed at reducing the number of conventional navaids, required as a backup infrastructure and contingency resource in the case of GNSS outage, to a minimum. In the Netherlands this program started with phasing out the first set of radio navigation beacons around ten years ago, while the rest of the superfluous navaids in the Amsterdam FIR have been progressively taken out of service in the 2019-2023 timeframe.

All ILS and DME stations still continue to operate; while four VORs in the country have been retained as a fallback and resilience network to manage the impact of GNSS disturbances. All other NDBs and VORs have been decommissioned. But how did we come to this promising story? What did we gain and what were the trade-offs made? How far is the implementation of PBN procedures in the Netherlands (before and after MON)? And how do we see the operational functioning of the MON and its evolution into the future?

Join Alejandra and Bart in this session to learn more about the practices and lessons learnt, and how industry and ANSP have worked together towards a successful outcome!
