Standards & Practices Update

We are pleased to announce that RP A-11, Personnel Qualification Requirements Operational Weight and Balance Control for Military Aircraft, and RP A-13, Weighing Reconciliation Techniques for Military Aircraft, are being posted to the SAWE website.

RP O-1, Offshore Terminology, is awaiting final approval and will be posted to the website sometime in January.  It is the result of a series of 20+ meeting of members of the Offshore Industry Committee in Houston, TX.

A revised RP-8, Weight and Balance Data Reporting Forms for Aircraft (Including Rotorcraft and Air-Breathing Unmanned Vehicles), is awaiting final approval and will be posted to the website upon completion.

Project Proposals for RP M-4, Vendor Weight Control for the Marine Industry , and RP A-6, Standard Coordinate System for Reporting the Mass Properties of Flight Vehicles, to become ANSI-SAWE Standards have been posted as well.

More information on RP A-11: The purpose of this document is to provide a recommended set of requirements for qualifying civilian contractor personnel to perform weight and balance control activities/tasks on operational military aircraft. Those tasks include but are not limited to the completion of military aircraft weight and balance control system forms, the creation and maintenance of aircraft weight and balance handbooks, the creation and approval of aircraft weight and balance flight clearance forms and the actual measurement of the weight and balance (center-of-gravity) of military aircraft.

More information on RP A-13: The objective of this Recommended Practice is to document methods and practices that have proven effective in the reconciliation of significant differences between measured weight and balance values obtained from actual weighing measurements and predicted values. These proven methods are applicable to most military aircraft, including transport, fighter, and unmanned aircraft, and are applicable to weighings accomplished using a variety of measurement equipment including portable weighing platforms, permanently installed weighing platforms, and top-of-jack load cells. Procedures and calculations relating to applying measured data towards the end product of calculating Basic Weight and Center of Gravity are well established in other industry standards and are beyond the scope of this document. For example, it is not the intent of this RP to address the details of any aircraft’s weighing procedure, but rather to provide guidance on what to do if weighing results are significantly different from predicted.

More Information on RP O-1 : To insure consistency across all weight management documents, in a multinational and multicultural project such as an offshore oil industry project, a centralized Weight Management Definitions document has been created.  At the onset of each project, a similar, weight management specific, definitions document should be issued to clarify weight management terminology to be used on that project.  This document starts with weight management terms as defined in ISO 19901-5: 2003.  Additional terms commonly used for weight management but not defined by ISO are also defined herein and, to the extent possible, have been defined per their most common industry usage
