Amendment: To seek members feedback on the airspace and procedures for Exercise Arnhem Thunder 2021

The issue


The Royal Australian Air Force (RAAF) will now be operating fast jet aircraft out of both Darwin and Tindal during Exercise Arnhem Thunder 2021 (AT21). Previously we advised that fast jets would not be operating out of Darwin Airport. There is no change to the proposed airspace, however there may be increased congestion and delay at Darwin Airport.

Please see the amended paper below for further details.

Details of previous submission:

Elements of the Royal Australian Air Force (RAAF) will be conducting Exercise ‘ARNHEM THUNDER 2021 (AT21)’ over the period 17 May – 04 June 2021.

AT21 is a high-end military activity, involving a wide range of tactical flying activities across Northern Territory, with aircraft operating from Darwin and Tindal.
