Agi, with regards to the systems, it looks like there is partial implementation. The Collins PL21 is a really interesting piece of kit, but I have not had time to use it on a cross country to understand its depth. The Carendo B350i for P3Dv4 also has a partial implementation of the PL21, and I really like it, especially as compared to a traditional FMS/CDU setup.
a. startup and shutdown procedures
b. engine controls and operations
c. autopilot controls and operations
d. partially operation of the electrical, pneumatic, hydraulic, fuel systems.
3. Emulation of Proline 21 avionics suite. Currently there is only one layout that will allow you to operate the aicraft in all scenarios. Many improvements will come in the future.
4. Installation in the 3D cockpit of the default X-Plane 11 FMC.
I’m watching this video now to get a feel for the systems. For sure I haven’t found a manual yet. That’s probably to be expected given the price. BTW, I consider watching this video necessary to operate the aircraft, since there doesn’t appear to be a manual. There are numerous bits of information that I found useful, like the YD switch being inop and having to press both AP buttons in order for it to engage.
