Product-Service systems (PSS) introduce the alternative for manufacturing firms to address sustainability in early development. In aeronautic industry, sustainability is an issue that challenges the innovation capabilities. The question if engineering tools and software are apt to manage innovation aspects guides the study in this paper. The study embarks from tools which can be categorised as knowledge based tools, and concludes that there are constraints that delimit the use in innovation projects. However, some of the constraints are more related to the approach rather than to the tools as such.
