Terminal Lugs: Everything You Need to Know

Electrical terminals come in a variety of styles. While most people are familiar with ring terminals and spade terminals, terminal lugs often go unnoticed. Like all electrical terminals, terminal lugs create a secure link between a cable and a fixed … Read More

Yaw Dampers: Keeping Airplanes Steady During Flight

Ever wonder how airplanes are able to stay so steady during flight? The answer is yaw dampers. As their name suggests, yaw dampers reduce or “dampen” an airplane’s yaw. The end result is a smoother, steadier flight. To learn more … Read More

The Beginner’s Guide to Keyed Washers

Washers are commonly used with bolts and nuts. Without them, the head of a bolt may dig into the surface of the fastened object, crushing and damaging the object. Washers prevent this from happening by distributing the bolt’s load across … Read More

Inspection Ports: Streamlining Aircraft Inspections

It’s no secret that airplanes undergo a lot of inspections. Commercial airliners typically undergo D-checks every six to 10 years and A-checks every four to six months. D-checks involve heavy maintenance like checking airframes and engines, whereas A-checks involve light … Read More

What Is a One-Pole Toggle Switch?

Toggle switches offer a simple and effective electrical control solution. They are often found in aircraft cockpits where they allow pilots to control various systems. There are different types of toggle switches, however, such as one-pole toggle switches. Toggle Switches … Read More

What Factors Affect Takeoff Distance?

Not all airplanes have the same takeoff distance. Also known as obstacle clearance takeoff distance, takeoff distance is the total horizontal distance an airplane requires to accelerate and take off to a specific altitude — typically 35 to 50 feet … Read More

Why Do Some Airframe Bolts Have a Hole in the Shank?

Airframe bolts play an important role in aerospace engineering. Like all bolts, they are used to fasten parts. You can secure two or more parts together by running a bolt through them. Installing a nut onto the end of the … Read More

The Beginner’s Guide to Pipe Unions

Disconnecting and reconnecting pipes can be laborious. Assuming the pipes use permanent fittings, you may have to cut them. An alternative to permanent fittings, however, is pipe unions. Pipe unions eliminate the need for cutting while allowing pipes to be … Read More

What Is Ground Effect in Aviation?

The altitude at which an airplane flies will affect its flight characteristics. At high altitudes, they typically experience better fuel efficiency. The air is less dense at high altitudes, so airplanes generate less drag. At low altitudes, conversely, the dense … Read More
