The paper discusses issues of developing a special measurement standard intended for the calibration of aircraft mass, mass center coordinates and inertia moments measuring instruments. The mathematical model of a special standard has been developed. It is based on the analytical principles for the determination of the mass center coordinates and inertia moments of homogeneous bodies with a regular geometric shape. The main sources of measurement uncertainty have been identified. Expressions for determining the uncertainty caused by deviations in the shape of the elements of which the measurement standard’s modules are composed, and uncertainty caused by heterogeneity of the standard’s material were obtained. The technical requirements to special measurement standards, complete with the scheme for the transfer of measurement units using special standards, methods of their calibration have been developed. Special standards have been created. Measuring instruments verification methods using special standards have been developed and approved.
