**2.5. Comparison of various UAVs**

**Figure 5** shows a comparison of the four different types of UAVs based on their average weights, payload size and flight time; **Table 1** on the other hand summarizes their in-flight specifications. For each category, a model UAV was selected. The values shown were obtained from the respective manufacturer documentation and/or operator's manual of each product. On **Table 1**, the advantage of the hybridization can clearly be seen, as it resulted in

higher flying altitude, wider control range, increased speed and longer flight time compared to the other UAV types.
