Proactive Action

Action organisation: Virgin Australia
Action number: AO-2013-095-NSA-022
Date: 07 August 2015
Action status: Closed

Virgin Australia reported that, on 7 June 2013, the following changes were made to its flight policies:

Flight Mode Annunciator Changes. Virgin Australia policy is that Flight Mode Annunciator [FMA] changes should be announced by the PF [pilot flying].

Due to high workload, FMA changes below 500AFE [above field elevation] only need to be made if required by specific aircraft operations manual.

The PM [pilot monitoring] should announce the change if missed by the PF.

Current issue status: Adequately addressed
Status justification:

The ATSB is satisfied that the change in policy requiring the announcement of flight mode changes has adequately addressed the safety issue.
