Add aircraft weight and balance impact to requirements

  • The requirement definition is in the Build or Revision status. You cannot specify weight and balance impact on active requirement definitions.
  • The requirement definition is not locked.

In a requirement definition, you can specify the impact that the work has on the weight and balance of the aircraft. When a requirement definition applies to several models of an aircraft assembly, you can specify a different weight and balance impact for each model, if required. This information helps your organization keep track of the total weight and center of gravity of each aircraft on which the requirement is performed.

Maintenix provides the report called the Weight and Balance Impact report that lists all the requirements completed on a given day that have an impact on the aircraft weight and balance, and that shows the value of these impacts. The report can be sent by email automatically to a controller who communicates this information to the flight crew. Information on how to configure the report server to send the report by email is provided in the Maintenix Administration Guide. You can also generate the report manually at any time.

  1. On the details page of the requirement definition, click the Details tab.
  2. In the Weight and Balance area, click .
  3. On the Add Weight and Balance page, provide the following information and click OK:
    • Minor Model: Select the model of the assembly to which the impact you are defining applies.

      When adding weight and balance impact for the first time on the requirement definition, you must add one to the Default model of the assembly to which the definition relates. If you have already defined the Default weight and balance impact, you can select another model of the assembly from the list.

      The list only displays the models that relate to the assembly and that do not have a weight and balance impact already defined in the requirement definition.

    • Weight: Enter the impact of the requirement on the weight of the aircraft. The default unit is pounds; your Maintenix administrator can change this unit if needed.
    • Moment: Enter the impact of the requirement on the balance (in moment) of the aircraft. The default unit used for moment is inch-pounds; your Maintenix administrator can change this unit if needed.
      Tip: You can edit the values assigned to a weight and balance impact by selecting the impact and clicking . To delete a weight and balance impact, select it and click . You cannot delete the Default weight and balance impact, but you can edit its values.
