<H2>Introduction</H2>

This index provides links to all on-line help texts currently available for the FDC toolbox. In the future, more sophisticated lists will be developed. See also the list of <A HREF="#References">references</A> for more information about the FDC toolbox.<BR><BR>

<A NAME= "ACmodel"></A><H3>Non-linear aircraft model</H3>

The FDC toolbox contains a generalized non-linear aircraft model. The aircraft-dependent parts of this model were designed for the De Havilland 'Beaver' aircraft, but it shouldn't be too difficult to adapt the model for other types of aircraft. This model is stored in the S<SMALL>IMULINK</SMALL> system <I><FONT SIZE=2 FACE="Arial","Helvetica","Sans Serif"><A HREF="beaver.htm">Beaver</A></FONT></I>. This contains the following subsystems (the table reflects the ordering within the system <I><FONT SIZE=2 FACE="Arial","Helvetica","Sans Serif">Beaver</FONT></I> itself, showing the full 'path' of each subsystem):<BR><BR><BR>
