While aircraft in general differ from one another, and this is especially the case with UAS, they do have certain aerodynamic and structural principles in common. This chapter deals with these shared flight principles, i.e., the physical phenomena and structural basis that allow an aircraft to take off.

Construction methods and components – as well as their limitations and restrictions – are also discussed. As stated above, it is important to apply the topics in this chapter to your specific UAS. The same applies when reading the data connection sections, in which you are taught the basics of radio wave propagation and the specific application of control and flight modes.

Finally, this chapter discusses maintenance and provides important information for ensuring your unmanned aircraft has a long life.

It is structured as follows:
