The Century IIb autopilot model is derived from the Century III development with the
pitch axis portions removed and a new 3D model in place of the Century III 3D model.
Required files required not in this folder are:
Aircraft/Generic/century2b.nas, and
'your aircraft folder'/Systems/CENTURYIIB.xml (the autopilot configuration).
The model and cascaded PID controller design attempt to recreate the performance
and pilot interface described in

Piper Aircraft used this autopilot from the mid 1960's through the mid 1970's.
It is used by the pa24-250-CIIB in FlightGear and the real pa24-250 N7764P has a
Century IIB autopilot.
The pa24-25-CIIB implementation uses the nasal file
Aircraft/Generic/century2b.nas
and the following xml files:
Aircraft/Instruments-3d/Century-IIB/AutopilotMode.xml,
Aircraft/Instruments-3d/Century-IIB/autopilotModePanel.xml,
Aircraft/Instruments-3d/Century-IIB/Century-IIB.xml, and
Aircraft/Instruments-3d/Century-IIB/Century-IIBPanel.xml.
The autopilot config file is Aircraft/pa24-250/Systems/CENTURYIIB.xml.
