How does an airplane turn in the air? How does it rise to a higher altitude or dive back toward the ground? First, let's consider the angle of attack, the angle that a wing (or airfoil) presents to oncoming air. The greater the angle of attack, the greater the lift. The smaller ...
An altimeter measures this air pressure to show the altitude of the airplane, or, how high it is above se a level. But the altimeter does not show how high the plane is above the ground. A plane might be flying at an altitude of 15,000 feet, but it would be only a thousand feet...

but of a design more similar to the wing on an airplane. Wind passing over the wing produces thrust, and a small tab on the end of the tail attached to the wing controls the angle of attack. The rudder controls the direction of the hull, and the keel keeps the saildrone upright. The...
