Weight estimation in aircraft design is very challenging due to the high number of variables involved in the creation of an accurate weight model, the numerous relationships between them and the high degree of uncertainty associated with the problem itself. This paper discusses a preliminary study on the use of fuzzy logic as an aid to the knowledge capture phase of the weight estimation process for aircraft structures. The results highlight the importance of multidisciplinary analysis in weight estimation from the preliminary stages of the aircraft design process.
