Takeoff and landing
- faster air flow → lower air pressure
- slower air flow → higher air pressure
- lift - Since the aerofoil is asymmetrical, the air above the wing has to cover a longer distance, so it travels faster than the air on the lower side. According to Bernoulli´s principle, the pressure of a flowing gas is lower when the speed is greater, therefore the pressure above the wing is smaller than that under the wing. The difference of pressure creates lift. Lift increases with speed.

As a milestone in the history of aviation, Oszkár Asboth´s first helicopter made its first flight in 1928.
The range of applications of unmanned aerial vehicles ('drones') keeps growing.
High speed generates a lift on airplane wings due to their asymmetrical profile.
