Pressure gauges were first created during the industrial revolution with the advent of the steam engine to monitor gas levels indicative of current engine operation. While essential throughout history, pressure gauges have evolved to provide countless devices with quick, reliable pressure readings for both gasses and fluids. However, as technology continues to modernize, analog pressure gauges are slowly fading in use, as digital gauges are gaining popularity for their capability of performing like analog gauges, but with additional benefits. However, the applications of analog pressure gauges should not be dissuaded, as there is various equipment that excels with their presence. Below, we will highlight the pros, cons, and overall differences between analog and pressure gauges which makes them unique. Read more >>

When working with a printed circuit board (PCB), it is vital to incorporate one or more resistors as a means of controlling current flow and for the benefit of other applications. These include dividing voltage, generating heat, matching and loading circuits, controlling gain, powering LED lights, and fixing time constraints. For any electronics project you might partake in, it is important to understand what exactly a resistor is, how it functions, and how to choose the right design. As such, this blog will provide a brief overview of all you need to know. Read more >>

In addition to full-scale wings, aircraft have a smaller set of wings known as “winglets.” The winglets extend off the end of the aircraft’s wings at an upward or downward angle as a means of increasing efficiency. Winglets function to decrease drag and can decrease fuel consumption by up to 4%. The ability to identify and understand how airplane winglets work is crucial to forming a more precise working knowledge of aeronautics, so the following blog will provide an overview for your benefit.

When it comes to safety, there are a lot of requirements that aircraft must meet to create a reasonably prepared environment for emergencies. Fire extinguishers are a common safety protocol in most public places, and a passenger aircraft is no exception. In fact, a strict passenger to portable fire extinguisher ratio must be maintained within most aircraft. Extinguishers are stored in both the cabin and the flight deck, and a variety of materials are used depending on the severity of the fire. This blog will cover the different types of extinguishing agents as well as the ideal situation in which each should be used in flight. Read more >>

The aircraft lavatory and wastewater system is quite interesting, making it possible to have a functioning restroom for passengers while traveling at extreme altitudes. While there are rumors that waste is simply dumped out of the aircraft during flight, this is simply not true. Rather, the wastewater system relies on a transfer chain and various assemblies to effectively and cleanly function. In this blog, we will discuss how the airplane water and wastewater system functions, allowing you to better understand how lavatory service is provided while in flight. Read more >>
