V: Change our velocity Let's start with V for velocity. The way we change our velocity is pretty straightforward. We can change our power setting, and we can change our altitude, switching potential energy into kinetic energy. Because velocity is squared, it generally does the most for us. CL : Change our coefficient of lift The CL is " a function of the shape of the wing and angle of attack. " Changing our angle of attack is straightforward-we modify pitch with elevator control. We have some control over the shape of the wing as well. " But wait! " you say. " Our wing is fixed! We cannot change it! " Not so. We can! And fun fact, when we do, it technically becomes a new airfoil. When we add in flaps, we change the shape of our wing and change how much lift it produces. We can also change the shape of the wing and increase lift with leading edge devices like slats. Now you know why all those STOL airplanes have such fancy wings. 44 FLIGHT TRAINING AUGUST 2024 Leading edge devices (above), while less common in GA aircraft, help create more lift. These are particularly valued in the tailwheel and short takeoff and landing community. Some flaps (below) both change the camber of the wing and add surface area, creating even more lift.
