This chapter gives a description of the requirements on the design and analysis of new Flight Control Laws (FCL's) for the ADMIRE model. The ADMIRE model is currently augmented with "conventional" FCL's. These are to be replaced with new FCL's based on new non-linear design methods. The current ADMIRE FCL's shall be used for the purposes of comparison with the new FCL's. The objective of the design task is to show the potential of different non-linear methods for aircraft flight control. © 2007 Springer-Verlag Berlin Heidelberg.
