It enables the instructor to create and carry out in-class online assessments, and facilitates organized instant communication for large classes. It is intended to improve the overall quality of a lecture by providing the instructor with continuous feedback on the students' understanding of the material.
X-Plane is a flight simulator that reads in the geometric shape of any aircraft and then figures out how that aircraft will fly. It does this via an engineering process called "blade element theory", which involves breaking the aircraft down into many small elements and then finding the forces on each little element many times per second. These forces are then converted into accelerations, which are then integrated to velocities and positions. This gives X-Plane the most realistic flight model available for personal computers.
