Aircraft rely on a complex navigation system that allows pilots to better orient themselves in the sky during flight. Common navigation instruments include aircraft systems and radio navigation aids (navaids) that are situated on board, and they all help to determine the position of the vehicle in the sky. Prior to takeoff, pilots must input a predetermined route into the flight management system of their aircraft, enabling them to monitor their route on cockpit screens throughout the flight. Aircraft navigation systems pinpoint the location of their respective aircraft and other vehicles present in the sky, in addition to mountains, airports, and poor weather conditions.

Conveyor belts are crucial components of the conveyor system in the industrial sector, as they are utilized mainly for the distribution, movement, and handling of materials in places like warehouses, factory assembly lines, and airports. Think of the conveyor belts travelers wait near in order to receive their luggage from the belly of the aircraft, or the assembly lines that people package food in. They move a number of items, including coal, sand, and grains. As such, you can find them in a number of industries, including manufacturing and packaging as well as power plants and clothing production. With a variety of applications, the belt itself needs to suit the system it is a part of, and there are many things to keep in mind when selecting your own. Below is a conveyor belt selection guide created for you.

In piping systems and applications that require the flow of fluids through a system of tubes, valves are used to control the flow of liquids and gasses by creating impenetrable barriers. With many materials and sizes of valves on the market available for different temperature and pressure ratings, on/off valves will typically be one of two configurations: ball valves or gate valves. Both are mainly intended to stop or start flow, but each has its own benefits, so your choice of which to use for your applications depends on the nature of your operations. As such, this blog will provide a brief overview of both ball valves and gate valves, as well as their unique characteristics and the settings in which each should be used.

In complex electrical systems, there are a number of devices that keep sensitive wires and cables protected and organized. An example of such components are wiring harnesses or cable assemblies, which serve to organize, consolidate, and protect electrical conductors. As wiring harnesses are generally customized according to application, they can dramatically improve a system’s efficiency.

Whether you are a beginner or an experienced professional, all pilots must be able to steadily rely on their devices for safe flights. The better equipped a pilot is with strong tools, he will be able to fly longer, make better informed judgements, and climb and descend with more ease. In addition to an altimeter, a barometer, and a GPS, a pilot should have a reliable variometer. A variometer shows climb and descent rates at its most basic, but there are a few types of variometers available for purchase. For your better understanding, this blog will cover what these devices do and how to choose the right one for your applications.

A simple mechanical component, bell cranks find many uses within commercial industries, including those pertaining to aircraft, automobile, and architectural construction. A specific crank that allows motion along an angle, bell cranks are commonly manufactured to operate with a 90- or 180-degree angle, but can ultimately be designed with an angle ranging from 0 to 360 degrees. For insight into bell cranks of various kinds and the mechanisms they are used for, we will briefly highlight some of the applications they serve.

Properly functioning refrigeration equipment is a necessity in any environment that may be inhabited for an extended period of time. Through access to adequate cooling measures, food spoilage may be delayed by slowing the growth of pathogenic bacteria. While most land-based facilities contain large refrigeration units, it is generally more challenging to set up and maintain the same in aircraft and ships. Due to the reduction in space and lack of access to power grids, aircraft and marine-based refrigeration units must be explicitly designed with these variables in mind. In this blog, we will discuss everything you need to know about marine refrigeration, including its various components and their nuances.

In a vehicle with a marine diesel engine, the fuel system maintains the quality of fuel through reliance on a fuel pump and a fuel injector. Ideally, the fuel within the engine has high combustion efficiency, which means that the particles of fuel quickly go through atomization, making fuel mix with air in the correct proportion. The engine relies on the proper timing and pressure of fuel injection in order to allow for proper atomization in the combustion chamber. This process relies on two main parts: the fuel pump and the fuel injector.

Capacitors are one of the many circuit elements that are a building block of modern electronics, and every electronic device will contain at least one capacitor in its assembly. In their most basic form, capacitors are passive components that temporarily store electric charges, and this simplistic operation is essential for the functionality of countless devices. As capacitors come in a number of forms with different ratings, it can be beneficial to have a basic understanding of how capacitors work and the varying options that are available.

Maintenance is an essential part of owning and operating any aircraft. The parts that make up these engines have a limited life that affects their ability to perform optimally, so they must be periodically replaced or repaired as needed for the engine unit itself to remain effective. A good pilot knows that without proper maintenance, these machines would quickly fail in their tasks. To ensure the engine's durability and a longer life, you need to maintain it. This will help limit wear on components that can directly or indirectly impact performance in various ways.

Engine life is highly dependent on the wear engines face, their operational use, the manufacturing processes they endure, overhaul procedures they are subjected to, and the aircraft they are installed into. While it is typically the manufacturer that sets engine removal times, other factors contribute to their eventual removal. In fact, certain engine types and their related components necessitate the removal or replacement of specific parts. That being said, this blog will cover the importance of aircraft engine removal and when such procedures should be carried out.
