I was wrong. If you activate APPR mode before intercepting the last fix, the aircraft will fly it perfectly.
Similar issues here, flight plan will not load and NAV does not work.
What is the flightplan you are trying to load?
Just to make everyone aware of one thing in this avionics set which is different compared to the Garmins.
When you load a direct A to B flightplan without any enroute waypoints or procedures set, you end up with only ORIGIN and DEST in the flight plan.
This is not a valid mission statement for these avionics and no flight path will be generated (no line on the map).
To solve this, put the the destination into the enroute plan.
Click the DEST line (1), this will copy the airport into the scratchpad.
Then click the line next to TO (2). And press EXEC.
This will put the destination into the enroute plan and now it will generate a flight path.
Another trap pilots might fall into is to have only arrival/approach procedures selected but no departure or enroute waypoints.
This might have you end up with something like this on the LEGS page.
You are now on a DISCONTINUITY because the plane doesnāt know how to connect the dots from where you are.
This is a simple fix too:
Click the line with the next waypoint which is CI21 here (1) and make it your active direct to waypoint (2) and then press EXEC.
It should now look like this
I would advise to do this after takeoff so it will generate the path from where your plane is currently at and LNAV autopilot will immediately capture it.
Here is another thing about LNAV autopilot.
Previous versions in the sim allowed you to just press NAV and the autopilot would fly you to the flight path no matter what. This was not accurate.
Instead in this case. LNAV will only be armed (white on the PFD)
This is fine. Now to have LNAV become active (green) you need to intercept the flight path (magenta line on the map).
You can do this by hand flying or using heading mode, to set a heading that intercepts the flight path.
When the plane gets close enough to the magenta line, LNAV will become green and the autopilot will now flight the path.
Just keep in mind before taking off, check your LEGS page and the map to see if a valid flight path is generated.

So, still not a fan of the flight model, BUT did have a bit more success with landings by keeping a bit of power in till touch down, and slowly powering down, as mentioned by Bishop(dev) up above. The takeoff is still a trainwreck though !!
Is the PFD-MFD wind direction and speed indicator modeled in AAU1? If so, how is it enabled as my current setup does not show that functionality.

It is not shown on the ground, only once you reach a certain speed (like 30kts or so).
- The plane will switch units based on your in-sim units setting
Is there a possibility to change this and bring back the setting? When I fly airliners, I normally fly european airlines, hence KGS, however, when flying private jets, even in Europe, most of them have their units in LBS, even european operators. Itās not practical to change the units in the sim everytime I want to fly the CJ4.

Thanks Bishop398. I just took a takeoff test and saw the wind direction and speed indicator come aliveā¦ 
Thanks so much for the detail, I will try your procedure and report the results. I was attempting to load KPDK to KECP.
So far your instructions are working nicely, and many thanks. My next test will be to check the legs and intercept the flight path, turning LNAV from white to green. I will also complete my entire flight from KPDK to KECP including an ILS approach.

Had some great flights last night and the navigation was spot on. However, I am noticing some control issues with my Thrustmaster Extreme 3D pro. CJ4 pitches up severely during takeoffs and landings. Pitched the nose down around 5-10 degrees with the elevator adjustment, but no improvement. I will work on calibration, which may have been impacted by the last upgrade. Had a similar issue with the Longitude.

How do you expand the map so you can see the whole flight path? It doesnāt zoom out far enough
The zoom levels currently modeled are the only zoom levels available in the real aircraft. Longer flights will not be able to be seen in total. To review the flight plan, you can use PLAN map mode and MFD ADV on the FMC.

Additionally, when you press UPR Menu (panel below the MFD) and select OFF, you will get a expanded map. Which offers a bit more space.

I donāt get wind speed or direction at any flight speed 
Iām not trying to beat a dead horse on this topic, but it was reinforced recently when I decided to complete a bunch of the landing challenges.
Several of them involve the CJ4. Upon activating the landing challenge, you are put in the air on final and usually around 120 kts with flaps 15. I trim nose down to relieve a lot of forward pressure that I need to apply to descend. When Iām fairly stable, at a good speed, and lined up, Iāll drop the gear. I remain on descent. When I then drop flaps 30, the pitch up is very strong and I find myself pushing the stick well forward to get back on descent. It feels very unnatural.
Now, this could all be totally normal, and Iām just an armchair pilot that doesnāt know aerodynamics any more than I understand quantum mechanics. But doing back to back landing challenges is really triggering my Spidey-senses on the flight model.
Iād be curious to see what others think if they go back and fly several of the CJ4 landing challenges.

Excellent tip/advice, especially the āDirect Toā method. Good stuff!
Anyone else now having issues with the CJ4 throttle, or seeing a partial reverse thrust on the hud when bringing throttle to zero?
After AAU1, things worked as expected. Using the Xbox controller, I have throttle set to Y (increase) and B (decrease). If I press and hold a button, it would continuously raise and lower the throttle. Now after the Canada update, if my mouse or camera center dot is over a control in the cockpit, the throttle is unresponsive to the controller inputs. I can press and hold until the cows come home and the throttle will not change. I have to move my camera or mouse to a āneutralā area with no controls under them to get throttle control back on the controller.
Iāve also noticed now if I press and hold the throttle decrease button, the hud will show the engines kick in to reverse thrust. Not enough to be functional, but the gauges go red to indicate reverse thrust and the lever shows 1% in reverse. Iām pretty sure the engines do increase rpmās a bit too.
