If you exclude or abstract too much, you may get false positives or false negatives. If you leave in too much, the model checker spends most of its time checking unnecessary code, wasting precious time and memory.
There are several different approaches you can take to obtaining a model of the system. They are, in increasing order of preference:
Yawing motion: Yawing motion means the sideways motion aircraft regarding the lateral axis. In other words side to side motion of the aircraft.
Models: Building an accurate model of the system is a major and critical step in program model checking. You need to create models of both the application to be model checked and the environment in which it is run, including all the input data and eve
