About x-plane:
X-plane is a flight simulator similar to the Microsoft flight simulator however it has many advantages in rendering aircraft performance and flight model realism. As a pilot myself I compared an aircraft I have personal experience flying the cessna 172, and found x-planes flight model to be more realistic.
