What Is a Circuit Breaker?

Circuit breakers play an important role in the electrical systems of airplanes. A typical airplane has hundreds if not thousands of electrical devices. With circuit breakers, a sudden surge of current won’t damage these devices. What is a circuit breaker … Read More

Understanding Stabilators and How They Work

Most airplanes don’t have completely flat and smooth wings. Rather, their wings feature adjustable flight control surfaces. Elevators, for instance, are hinged control surfaces that allow pilots to control the airplane’s pitch. In addition to elevators, some airplanes feature stabilators … Read More

What Are Non-Metallic Washers Used For?

Washers are commonly used to protect parts from the load of threaded bolts. When driving a bolt into a part, you’ll expose the part to mechanical stress. The head of the bolt will press against the upper surface of the … Read More

What Are Secondary Flight Controls?

Modern airplanes are equipped with a variety of control mechanisms. Consisting of knobs, levers, dials, pedals and buttons, they allow pilots to control the airplane. In addition to primary flight controls, however, there are secondary flight controls. To learn more … Read More
