The issue
This proposal notes the following key issues:
- Conditional status of TRA ‘NIMBUS’ west of RAAF Amberley will be RA2.
- Multiple air routes affected. Diversion routes to be published in the Aeronautical Information Publication Supplement (AIP SUPP).
- Access to TRA is limited to exercise participates, aircraft with a declared emergency or undertaking operations in the preservation of life and/or property.
