SITL runs flight-stack software against a simulated vehicle. It is a lower-risk way to test logic and mission scripts; it does not simulate every mechanical or regulatory hazard.

Your exercise
Identify a supported PX4 simulation workflow and describe the environment and version you would record.
Practice in simulation or at safe low voltage unless supervised by qualified personnel. Follow official equipment safety guidance.
Record your engineering notes
Capture a hypothesis, your observations, test evidence, failure cases or the next experiment. These notes stay in your browser unless you export them.

What is the core advantage of SITL?
Practice quizzes are formative and can be retried. Answers are evaluated in your browser; they are not proctored exams.
