When implementing wire or cable assemblies within an aircraft or general space, it is important that they are well organized for the ease of installation, inspections, and maintenance. One of the most simplistic, yet reliable, methods of wire and cable management is to use lacing and tying. Cotton or nylon cord serves as the most common materials for such procedures, each providing their own resistances for protection. As wires and cables may be tied or laced in various ways, it is best to have an understanding of each method and how they may be implemented.

Resistors are a common component regularly found in electrical circuits, capable of reducing current flow, adjusting signal levels, dividing voltages, terminating transmission lines, and much more. With their many abilities, resistors are essential for the proper and safe operation of countless electronic devices and applications.

A Dual In-Line Package (DIP) switch is a set of electrical switches packaged in a small box or housing. They are designed to be mounted on printed circuit boards to provide a range of electrical inputs to an electronic device based on the position of the individual switches. They are typically arranged in a line or, in the case of a rotary DIP, a circle. DIP switches serve as an alternative to jumper blocks. Their main advantages are their ability to quickly change positions and the fact that there are no parts to lose. However, the popularity of DIP switches has waned in recent times thanks to the rise of customizable software configurations.

In an air compressor, the head gasket serves to form a seal between the cylinder head and the valve plate assembly. After prolonged use, the inner portion of the gasket will likely begin to deteriorate, causing a leak within the compressor pump. The head gasket is also susceptible to damage and should be inspected whenever the pump is serviced. If your compressor isn’t working up to standard, replacing the gasket head may be the solution. In this blog, we will cover the twelve steps to replacing the head gasket on an air compressor.

An aircraft flap is a high-lift device mounted on the wing-trailing edges of an aircraft where they increase an aircraft wing’s lift. Flaps also produce extra lift when an aircraft is taking off and, when they are extended, increase the curvature of the wing to help the aircraft generate lift even at low speeds. Essentially, aircraft flaps adapt to aid in whatever phase of flight your aircraft is in. Despite them all carrying out relatively similar functions, there are multiple types of aircraft flaps. In this blog, we will discuss the six most common types and explain their unique characteristics.

Ground power units, a crucial part of any hangar, are vehicles used to supply power to an aircraft parked on a runway or in a hangar. Every ground power unit, or GPU, provides a specified power through the use of an electrical system, a battery pack, and a gasoline, diesel, or small turbine engine. Since their inception, GPUs have allowed for ground support equipment to both become smaller and increase in efficiency. But what exactly does a GPU do, and what are the different types? This blog will explain the types of GPUs, their function, and mistakes to avoid when buying one.

When establishing or replacing parts for piping, tubing, and other similar systems that feature many interconnected components, it can oftentimes be difficult to find exact fits for connecting installations. For fluid applications in particular, or for those where fluids must not enter a system, having imperfect fits can lead to leaking, damage, and more. As such, parts often require a middle component to act as a compressed seal to close off the assembly. An O-ring, or packing, is a torus-shaped mechanical gasket that is used in such instances, providing countless assemblies with sealing action through its simplistic design. As O-rings are widely used across many applications as one of the most common sealing components, understanding their construction and functionality can be highly beneficial.

In regards to electronics and electrical systems, potentiometers are a type of three-terminal resistor that allows for the manual adjustment of resistance to govern current flow. With their various types, potentiometers serve many applications such as audio, television, motion control, transducers, and computations as a variable resistor or rheostat. To best understand how potentiometers can be used for a particular system, it is best to be aware of their functionality and common types.

Flight recorders, otherwise known as a “black box”, are flight instruments that record and store the state and performance of an aircraft during operation. Two components, the flight data recorder and the cockpit voice recorder, are the standard parts that make up each flight recorder. Together, the flight recorder is able to record pertinent information from the aircraft flight instruments and cockpit such as altitude, speed, vertical acceleration, pitch, pilot cockpit communication, radio transmissions, and much more.

While the average flyer might not be as familiar with aircraft powered by turboprop engines and propellers, they are found in many single, twin and commuter aircraft. Single and twin engine aircraft use the Pratt & Whitney PT-6 turboprop engine, a popular option with power spanning from 500 to 2,000 shaft horsepower.

The attitude indicator, sometimes known as the artificial horizon, is a flight instrument that denotes an aircraft's orientation relative to the earth's horizon and provides immediate indication of any orientation changes. It shows rotation about the longitudinal axis to indicate the degree of bank, and the lateral axis to display pitch.

Like automobiles, aircraft mount batteries that are used in the ignition sequence for the engines and auxiliary power unit (APU). Unlike car batteries however, aircraft batteries are responsible for much more. If there is an electrical generation failure during a flight, the batteries will be required to provide power until the aircraft can land, and can also be used to restart the engines if a flame-out occurs.

Control surface failures are thankfully rare, but easily some of the most stressful malfunctions a pilot can face. Occurring mostly during takeoff, a control surface failure compounds an already tense moment, adding to the issues and factors a pilot already faces in such a situation. Thankfully, by keeping a clear head and taking prompt action, the pilot can prevent an accident from occurring.

As you prepare to go on a long car journey, you will likely need to check the fuel levels of your car. Luckily for you, there is a handy dial in the dashboard of your car which indicates your fuel supply. A pilot has a similar routine inside the cockpit, however, the miles covered are significantly more and the implications far more costly. Additionally, the fuel system of an aircraft is far more complex than in a car. Luckily for the pilot, a variety of fuel system indicators provide a comprehensive view of the system’s health.

On an aircraft, there are multiple electrical systems that play their part in ensuring the proper functioning and sustaining flight. Just like your house needs an electricity source, an aircraft needs a reliable source of power that will not only start up the aircraft but keep it running with all the various aircraft lights and indicators.

There a few key components of an electrical system that are found in all aircraft. While they may be more advanced in some aircraft, the underlying principles and features of an electrical system are the same throughout the various makes and models. There are switches, backup batteries, alternators, and voltage regulators. Like a typical electric system, electrical energy needs to be diverted and stored to prevent system outages.

Aircraft material failures are one of the leading causes of aircraft engine failure. One of the most prevalent failures involves aircraft metal fatigue. The term refers to the exposure of metal aircraft components to continuous load stress, which leads to the accumulation of microcracks, and thus the weakening of said components. Determining whether aircraft metal fatigue will occur is not a matter of if, but when. Let’s examine how metal fatigue is caused over the life cycle of an aircraft, and how manufacturers determine fatigue limits and inspection.

Believe it or not, but traveling by plane is significantly safer than by car. The many protocols, regulations, and safety nets commonly used in aviation simply outclass those implemented in standard vehicles. So, when a plane crashes, it comes instantaneous news and investigators work tirelessly to find out what happened. And their first clue is the aircraft black box.
