Proposed decommissioning of Leinster, WA non-directional beacon

Broken Hill Proprietary Company Limited (BHP) is proposing to decommission the Leinster (LST) non-directional beacon (NDB).

The issue

While LST NDB is a privately owned NDB, it is currently part of Australia’s backup navigation network (BNN).  However, removal is not expected to adversely impact the important function of the BNN, as adequate coverage is provided by other navigation aids. 

Decommissioning of the LST NDB will result in the following changes to the Aeronautical Information Package (AIP):  

• removal of the LST NDB details from ERSA 
• removal of the YLST NDB approach and GNSS Arrival procedures 
• modification of routes that reference LST NDB 
• updating of charts and other documentation to remove reference to the navaid.  

The existing required navigation performance (RNP) approach procedures will not be affected.

Purpose

BHP, as the owner of the LST NDB, is proposing to decommission the navigation aid.

Airservices is seeking feedback from aircraft operators and other industry stakeholders to understand, if and how, the LST NDB is being used and whether decommissioning it will have any impact on their operations.
