Who are you? We are the engineers from Abbott Aerospace UK Ltd.

Why do You do this for free? A lot of the library material does not originate with us so, with good conscience, we cannot charge for that part of the library. There are issues with commercializing the material that we create, copy protection, customer support and pricing at the right level. By making everything available free of charge it lets us concentrate on content.

How is the library funded? The library is funded using revenue from the engineering service side of Abbott Aerospace UK Ltd., and by the donations of the people who find the library useful.

I would like to help the library by volunteering my time. How do I do that? At the present time we are unable to accept any offers of help. In the future we would like to work with a group of volunteer engineers. At this time we have not developed the digital infrastructure to make this possible. You can help by making a donation of any size.
