This paper briefly outlines how a combination of various computational methodologies could reduce the enormous computational costs envisioned in using advanced CFD codes in gradient-based optimized multidisciplinary design (MdD) procedures. Implications of these MdD requirements upon advanced CFD codes are somewhat different than those imposed by a 'single' discipline design. A means for satisfying these MdD requirements for gradient information is presented which appears to permit: first, some leeway in the CFD solution algorithms which can be used; second, an extension to 3-D problems; and third, straightforward use of other computational methodologies. Many of these observations have previously been discussed as possibilities for doing parts of the problem more efficiently; the contribution here is observing how they fit together in a mutually beneficial way.
