X-Plane comes with a Cessna 172 by default. It’s an competent plane and it is what I have flown since I got X-Plane 11 back in May of 2017. I wanted more realism so I purchased the after-market Cessna 172 by Airfoil Labs.
It was buggy and presented several challenges to flying. I had to learn how to land all over again. There were several graphical issues that prevented me from flying the AFL 172 at all. I got fed up and uninstalled it.
After reading posts from other sim pilots on X-Plane.org’s forum, I discovered another approach. Now, I fly the default Cessna 172 with the Reality Expansion Pack ($19.99) installed on top of it.
The aircraft experience feels more immersive, because I’m not just flying a virtual plane, I’m managing the entire aircraft from when I approach it on the tarmac to take-off to flight to landing and finally when I park it. I even conduct maintenance on it like I would a real airplane.
The REP has been very stable, too. There was one sound error that occurred, but removing the Cessna 172 from the list of possible AI aircraft fixed the problem.
So far, I’m very impressed with this approach.
