I recently came across a FS2020 user who discussed this feature and uploaded a video displaying 4 minutes leading up to and including landing and taxiing.
The user didn't detail how they did it - ergo, I had to conduct some research and discovered the methodology.
I finally tried this feature out on the A320 Neo - and I must say, it worked pretty darn well overall.
The only issue the co-pilot was causing, was a constant over-speed warning throughout the flight until setting up for landing. This overspeed was causing the aircraft to overshoot some waypoints on the flight plan. In this instance, 2 wp's were overshot and the co-pilot had to maneuvre/circle back to correct this.
I opted to alternate passenger seats from internal Wing View and internal Engine View.
It was an absolute blast. I can only imagine if a 3rd party dev (freeware or payware) jumps onto this - the possibilities are almost endless. Great immersion.
And, the Co-Pilot landed qualitatively/safely and taxied to the gate. No injuries to passenger, or damage to aircraft.
So if you weren't aware of this feature, or you were aware and haven't tried it yet - it's well worth it.
