Models a FCSFunction object.
One of the most recent additions to the FCS component set is the FCS Function component. This component allows a function to be created when no other component is suitable. Available mathematical operations are described in the FGFunction class. The function component is defined as follows:
The function definition itself can include a nested series of products, sums, quotients, etc. as well as trig and other math functions. Here's an example of a function (from an aero specification):
