Many aircraft are equipped with either a 14- or 28-volt direct current electrical system. Some systems are more advanced than others, but the basic aircraft electrical system comprises the following components: alternator/generator, battery, master/battery switch, alternator/generator switch, bus bar, fuses, & circuit breakers, voltage regulator, ammeter/load meter, and the associated electrical wiring. In this blog, we will discuss the main parts of aircraft electrical systems.

The aircraft hydraulic system is an extremely important element of numerous aircraft, allowing for high amounts of energy to be transferred for the actuation of systems and flight surfaces. As a system that relies upon contained liquids under pressure, hydraulics may be used for opening cargo doors, deploying landing gear, actuating aircraft rudders and spoilers, operating windshield wipers, and much more. As hydraulic systems help both small and large tasks be carried out, their proper functionality is paramount. While a number of factors can affect the functionality of hydraulic systems, the most important are temperature and pressure.

Networks are critical for supporting business, fostering communication, providing entertainment, and beyond. A key component of every network is the network switch, which allows devices within the network to connect to transmit data and share resources. The network switch operates at the Data Link layer of the OSI model (layer 2). It receives packets being sent by devices connected to its physical ports and redistributes them through the ports that lead to the device to which the packet is intended to go. They are also able to work at the network layer, layer 3, where routing occurs. While switches are used in networks based on ethernet, Fibre Channel, ATM (Asynchronous Transfer Mode), and InfiniBand, the majority of switches use ethernet.

Whether they are electromechanical or solid state, relays, solenoids, and contactors are all examples of switches. However, they all have differences and unique characteristics that make them better suited to different applications. This blog will cover all three and discuss certain considerations to make when deciding which device is best for you.

When watching a propeller aircraft begin to operate as the engine is turned on, it can be astounding to witness just how fast propellers can spin. Due to the speed at which propellers are operated at for achieving sufficient thrust, it can be difficult to see which way they are revolving. Furthermore, one may wonder if there is a standard for direction, and whether all move the same way. While a grand number of propellers tend to spin in a clockwise direction, there are some outliers that present the opposite operation.

Flight control surfaces are common aircraft devices that allow for pilots to manipulate the flight dynamics of the vehicle. Coming in the form of aviation parts such as ailerons, elevators, rudders, spoilers, and flaps, flight control surfaces are paramount for the efficiency and optimization of piloting and flight. As aircraft often operate in environments where they may face strong winds, prop washer, or jet efflux hazards, various means of protection are implemented in order to ensure the safety of such components.

On any fighter type jet, a circuit breaker panel is found on the underbelly or side of the cockpit, right below where the pilot would sit. Much like a circuit breaker you would find at home, the aircraft circuit breaker would be like a box or panel that acts like a protective device for opening a circuit automatically when excessive current is flowing through it. A circuit breaker may be reset to restore the circuit after a fault causing excessive current has been corrected. Essentially the circuit breaker panel is an electrical protecting safety device which is why most homes, helicopters, airplanes, and other facilities must have a circuit breaker.

Precision shims are useful aircraft mating components, allowing for the gaps between mating components to be filled in order to provide a precise fit for assemblies. As a result, utilizing precision shims can save a great amount of manufacturing costs as individual parts do not need to be precisely machined in order to operate efficiently in the assembly. Additionally, precision shims can protect the surfaces of mating components, extending their service lives and further decreasing the amount of assembly time and money it takes to maintain a system. In general, the two main types of precision shims that are commonly used include laminated shims and edge bonded shims, each providing their unique benefits to assemblies.

Within the realm of aviation, there are many types of vehicles that fall under the Federal Aviation Administration’s official definition of aircraft. These include airplanes, rotorcraft, airships, gliders, paramotors, and hot air balloons. In regards to airplanes in particular, they are described by the FAA as a fixed-wing aircraft that are heavier-than-air and engine driven. While a plethora of fixed-wing aircraft types exist for various civil, military, and government applications, most share common major components that allow them to perform flight operations with ease. Across all fixed-wing aircraft types, the common major components include the fuselage, wings, empennage, and landing gear.

The Fixed Base Operator (or FBO) is a commonly used term in the business aviation industry. However, despite this, few people really know what a Fixed Base Operator is. The term originated in the United States after World War I, a time when the aviation industry was essentially completely unregulated. The majority of pilots were either stunt performers (called barnstormers) or very short-distance commuter pilots in retired military aircraft. These pilots would often land in open fields on farms where they would make camp. These temporary bases were the original civilian airfields.
