+# TOPIC 8
+Develop an R-based software, which will perform the following tasks:
+1. Download from the OpenSky Network online database the observations of the trajectory of a randomly selected aircraft on a randomly selected flight over at least five days, in uninterrupted continuity, perform the selections in the graphical user interface (GUI) of your R script,
+2. determine the characteristics of each trajectory according to the parameters: diffusion distance, straightness, duration of travel, mean travel velocity and fractal dimension, using the R library trajr, (4) perform basic statistical analysis of the parameters of daily trajectories from
+3. arithmetic mean, variance, quartiles, boxplot, estimate of the density
+function of the experimental statistical distribution, analyze and interpret them.
+4. Demonstrate the
+application of the developed software support on a selected example of use. In the final project report,
+describe the problem, describe the method and the developed software support in the R environment,
+present and interpret the results, and form a conclusion.
