Can conventional navigation procedures be used after 6 June 2030?

The PBN IR expressly excludes the use of conventional navigation procedures as from 6 June of 2030, except in the event of PBN contingencies, i.e., situations where, for unexpected reasons beyond the control of ATM/ANS service providers, GNSS or other methods used for performance-based navigation are no longer available.

From 6 June 2030, PBN will be the normal means of navigation, supplemented with navigation supported by CAT II/III landing systems, where necessary.
