ADS is the new standard for the conceptual design of the modern generation of light aircraft. The know-how of OAD was translated into ADS, a powerful software tool which is now on the market and available for aircraft designers, amateur builders, universities and research institutes.

Didier Breyne, founder of OAD, has a degree in mechanical engineering. He has several years of work experience in nuclear physics as Project Manager for a research centre. In addition, he has several years of experience in the development of software for modelling atmospheric activity.

The development of ADS takes several years, since he is also working on the design of a light aircraft. Based on his experiences in conceptual design, he understands that the conceptual design is an essential stage in the development of a product.

Although there is no lack of literature on the subject, he could not find a 'roadmap', nor even a software package for doing the conceptual design of his light aircraft quickly, easily and with accuracy.

At this point came the idea of ADS, which took six years to develop.
