Airplane Sensors

From this description you can see that a plane has four different moveable control surfaces, as shown here:

The plane also has two different sensors mounted on the wing:

The L-shaped tube is called a pitot tube. Air that rams into this tube during flight creates pressure, and that pressure moves the needle on the air-speed indicator in the cockpit. The small opening on the right is a whistle that sounds as the wing nears a stall. The larger opening visible near the cockpit is used for ventilation.
