Validation of landing weight

Issue number: AO-2010-081-SI-03
Who it affects:
Issue owner: Cobham Aviation Services Australia
Operation affected: Aviation: Air transport
Background: Investigation Report AO-2010-081
Date: 09 February 2012

Safety issue description

The operators procedures did not include a validation check of the landing weight generated by the flight management system which resulted in lack of assurance that the approach and landing speeds were valid.

Proactive Action

Action organisation: Cobham Aviation Services Australia
Action number: AO-2010-081-NSA-028
Date: 09 February 2012
Action status: Closed
A number of enhancements to procedures were introduced as a result of this occurrence. In the first place, prior to departure, the landing weight from the aircraft’s load sheet is required to be entered onto the landing take-off and landing data (TOLD) card. Then, prior to establishing the approach speeds, the pilot monitoring is now required to call out the landing weight from the FMS, and the pilot flying will confirm this with the expected landing weight that is written on the TOLD card and call ‘landing weight checked’.
   
Current issue status: Adequately addressed
Status justification: The Landing weight is now transposed from the loadsheet to the TOLD card for comparison with the FMS prior to approach preparations.
