This document provides the means for establishing a system of mass properties management and control during the acquisition phases (pre-concept, concept exploration, demonstration/validation, engineering & manufacturing development, production & deployment, operation & support, major modification) of heavier-than-air aircraft programs. It contains a set of recommended practices from which selection may be made or tailored to satisfy the discrete requirements of each program.
The contractor shall develop achievable mass properties objectives and assist the customer (government) in specifying Performance Specification mass properties requirements. During the initial development of, or any subsequent change to, mass properties objectives, the contractor shall give particular attention to substantiating data, mass properties dependent design information and the mass properties uncertainties and consequences. Throughout the contract life cycle, the contractor shall maintain cognizance of the vehicle mass properties limits whether established by contract, system performance or by subsystem design. The compatibility of total system mass properties requirements with configuration requirements shall be assessed to assure that program objectives can be met.
Notes:
This document is also applicable to Uninhabited Air Vehicles (UAVs) which are re-usable and/or re-configurable in the field. For UAVs that are not re-usable and not re-configurable in the field, see Recommended Practice No. 9, Weight and Balance Control System for Guided Missiles.

Personnel Qualification Requirements — Operational Weight and Balance Control for Military Aircraft https://www.sawe.org/product/sawe-rp-a-11-2015/ Tue, 05 Apr 2022 21:45:00 +0000 https://www.sawe.org//?post_type=product&p=5725 Scope The qualification requirements in this recommended practice are applicable to all civilian contractors supporting weight and balance on operational military aircraft. Purpose 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.  ]]> Scope The qualification requirements in this recommended practice are applicable to all civilian contractors supporting weight and balance on operational military aircraft.

Weighing Reconciliation Techniques for Military Aircraft https://www.sawe.org/product/sawe-rp-a-13-2015/ Tue, 05 Apr 2022 21:45:00 +0000 https://www.sawe.org//?post_type=product&p=5726 Scope 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. Purpose This SAWE Recommended Practice provides guidelines for reconciling weight and balance measurements against predicted values for military aircraft.  ]]> Scope 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.
