Abstract
Nowadays, everybody can hear about different drone technologies, as they continuously appear in everyday life. It is easy to see on the internet how many possibilities are available with a drone. The hobby use of aerial photography can be regarded as basic, but this photographic feature can also be used for professional purposes, such as at different festivals, weddings, and by the police. However, operating a drone is still not a toy-like activity. Especially for larger drones, but also for smaller ones, several steps are necessary to operate them safely. Sometimes it occurs, especially for older or slightly damaged drones, that testing and diagnostic are necessary to obtain information about the malfunctions. Educational purposes are also important in engineering education, and basic drone education should be extended with diagnostic viewpoints. This paper introduces different diagnostic techniques for drones, our own experiences, and their usability in education.
