Avionics Architecture Standards as an Approach to Obsolescence Management

Abstract : Obsolescence management techniques can be categorized as either production engineering based techniques that attempt to control an existing situation or design based approaches that attempt to minimize the initial problem. This paper addresses system architecture design as an approach to obsolescence management. The work of the ASAAC program in developing open architecture standards designed to exhibit a high level of obsolescence robustness is described. Other issues that relate to the financing and organization of obsolescence management are also discussed.
