Flying an unmanned aircraft operates on a number of aerodynamic principles as described above in this section. However, aerodynamics also carry risks. For unmanned rotor aircraft, there are two potential risks.
Downwash
The downward deflection of air created after a wing profile interrupts the undisturbed airflow is also called downwash. Due to the shape and position of the wing profile, downwash will always occur when lift is generated by a wing.
