The GNLU in the RJ is more akin to an FMS that is found in a 737 rather than an A320, but we have simulated it to a similar depth as our UNS-1 in the 146. The GNLU is, however, a much more modern and complex unit, with more advanced features than the UNS-1 so there should be plenty to keep you busy. Like our UNS-1, we have simulated as much as possible to be functional using the real-world FMS manuals, including the ability to create holding patterns and runway extension waypoints, view Top of Climb and Top of Descent points, and monitor other navigation and performance data.
There has been a significant rewrite of the autopilot code in the RJ as that was required to allow us to properly simulate how the various aircraft systems all integrated with each other (Flight Guidance System, AutoThrottle, FADEC, Thrust Rating Panel, etc), so there have been improvements to the autopilot across the board. The RJ is also capable of CAT3 autolands in the real world and in the sim, which these autopilot improvements have been crucial for.
With regards to a release date we have nothing to announce at the moment, but do keep an eye on our social media channels as we'll be sharing more information on the RJ Professional soon.
