Keywords: multidisciplinary, optimization, indirect method, distributed criteria

The philosophy of the new approach to multi-disciplinary optimization of aircraft parameters by a target criterion are formulated in view of requirements of aerodynamics, flight dynamics & control, and strength. The idea of a local de-composition of the initial problem into mono-disciplinary subtasks with special criteria, Local Distributed Criteria (LDC), is used. The regular method of LDC formation is proposed on the basis of sensitivity functions.
