Introduction

Project: Develop STD Format for Weight Reporting in Aviation IndustryBackground

During the 71st SAWE Int’l Conf in Germany, Dominik Wacht, Head of the Airbus MP, presented “Mass Properties challenges in the Extended Enterprise environment” during the Airline Affairs break out session. Robert McIntosh, his Boeing counterpart expressed that Boeing faced the same challenges. Other OEM and suppliers reps at the meeting also agreed that there were opportunities for improvement in the relationship, especially on data reporting. The diversity of Weight Report templates in use by all parties led to unnecessary workload and often times to confusion.

It was recognized by all a pressing need for standardization and this project was born. It is also a double test case: a) Industry working together to develop STDs through SAWE and b) pursue development as SAWE RP but working under ANSI rules and eventually submit the RP as candidate to become an ANSI STD (SAWE’s first).

The Drivers

• Concentrate on aviation industry. Other industries encouraged to benchmark work. • A Standard to report essential weight & CG data in an efficient manner. • A consistent format to be called out in a SOW that will facilitate understanding. • A standard which includes a recommended report format for each phase so primary

contractors know where to look for a datum and can easily compare reports from multiple vendors.

• A standard segmented enough to only require that data which is necessary for each phase of the lifecycle process including at a minimum; pre contract contractual ‐maximum weight development, design status reporting, first article verification and production weight verification so the cost of vendor mass properties to the platform is no more than necessary.

• A timeline driven Weight reporting method that would allow the Weight report to be reduced in size and scope as the design matures from Development to Production.

• A value added Standard Practice for Weight Reporting that can be used to satisfy everyone involved without having to customize multiple report formats for various customers.

• To develop a RP/Standard for establishing, maintaining and managing the Mass Properties data and reporting requirements for a system throughout it's lifecycle driven by customer needs.
