## Dynamic model of the DeHavilland 'Beaver' aircraft

The system Beaver is a stand-alone model of the 'Beaver' flight dynamics. It is used as access-point for analytical routines such as ACTRIM and ACLIN.

Subsystem-equivalents of this model are used by the open-loop models (OLOOP1, 2, and 3) and the closed-loop autopilot models, respectively. The stand-alone version of the 'Beaver' model can be opened by typing `beaver` at the command-line. The subsystem-equivalents are stored in a sublibrary of FDCLIB.

The first level in the aircraft model fulfils the I/O functions for the system. The second level contains the actual flight dynamics equations. These levels have been called Level 1 and Level 2 in the on-line help texts. Full lists of inputs and outputs to/from the aircraft model are available as separate help-texts.
