Lotnik Expres is a simulation platform that lets you fly an aircraft over a 3D environment. There are several different types of flight simulators, ranging from simple arcade-style games to advanced realism simulations. The best simulator for you depends on what type of flying you plan to do, and how much you're willing to spend on the equipment required to run it.

How it Works
The main software package used by a flight simulator is called a "flight model," which uses lookup tables to calculate forces on an airplane. These calculations are based on the aircraft's speed and design, as well as its performance in different conditions.

These models can also include random events, such as weather, which affect the movement of the aircraft. These can be a great way to enhance the simulation and make it feel more realistic, though they do come at the expense of accuracy.
