<h2>
Aircraft trim program <i>ACTRIM</i>
</h2>
<p><i>ACTRIM</i> is a Matlab program, which can be applied to Simulink
implementations of non-linear aircraft models in order to determine
steady-state trimmed-flight conditions.</p>
<p><i>ACTRIM</i> has been written for
the Simulink <i><a href="beaver.htm">Beaver</a></i> model, which can be
opened by typing <code>beaver</code> at the Matlab command line. The trim
routine can also be applied to other aircraft models in Simulink if they use
exactly the same definitions of the input and state vectors as the system
<i>Beaver</i>. However, if this is not the case, it is relatively easy to
adapt the source code <small>ACTRIM.M</small> for the new situation (it is
recommended to take a closer look at the source-code to see how it works).</p>
