The Rockwell Collins website doesn't have anything about this plug-in. The Eclipse Marketplace, the place where all these plug-ins are hosted, doesn't appear to offer the possibility to acquire it which could mean that the product you're trying to acquire is discontinued.
However, to confirm this, I recommend contacting the original developers of the application through the following link: https://www.rockwellcollins.com/Contact_Us.aspx
