To properly maintain and regulate aircraft elevation, altimeters are used to measure aircraft altitude. Constructed to calculate the height, or altimetry, from aircraft to the surface below, there are varying types of altimeters that can be used to achieve this specific reading. Having this in mind, although not all altimeters are used solely for flight, four primary altimeter types are commonly seen amongst aircraft. These include barometric altimeters, radio altimeters, GNSS (GPS, Galileo, etc.), and laser altimeters. Of these four instruments, we will discuss each and their uses below, which are most commonly used today, and why each is practical for different types of aircraft.

A diaphragm valve is a bi-directional, on/off throttle valve used to control fluid by regulating the area through which media (such as a fluid) can enter and exit the valve, thereby changing its speed and velocity. The name diaphragm valve comes from the thin, flexible membrane used to control the opening and closing of the valve. They can be made from materials including stainless steel, plastic, or even single-use materials. Diaphragm valves are similar to pinch valves, but use a linear compressor to push the thin diaphragm into contact with the valve body. They provide discrete and variable pressure control and can be either manually or automatically actuated.

RF connectors are a type of connector used to transmit radio frequency signals by connecting transmission lines to various applications. In this blog, we will discuss five of the most common types of RF connectors: Bayonet Neill-Concelman (BNC), Subminiature A (SMA), Subminiature B (SMB), N-Type, and Threaded Neill Concelman (TNC). Before we look at RF connectors, it is important to understand how coaxial cables work. For a connector to transmit a radio frequency, there must be a transmission line. Coaxial cables are the most commonly used transmission line, as they have both inner and outer conductors, meaning coaxial cables experience less loss of signal and can be used in close proximity to metal objects without interference.

A swept wing is the most common planform for transonic and supersonic jet aircraft. Swept back wings are by far the most common, but forward and variable sweep wings are also in use. You may have noticed an aircraft with swept wings and found yourself wondering why they look that way. The purpose of swept wings is to reduce drag, therefore allowing an aircraft to fly faster. However, how they do this is not as simple to explain. Essentially, sweeping the wings makes the aircraft feel as if it is flying slower. In turn, this delays the effect of supersonic airflow, therefore delaying wave drag.

If you work in aviation, you will undoubtedly have heard the term TSO. In an industry with so many different technical terms, parts, and practices, acronyms and abbreviations like TSO can become difficult to remember. This blog will cover TSOs, or technical standard orders, in detail.

For the typical aircraft engine to operate efficiently, it requires an optimal fuel and air mixture for propulsion generation. As an aircraft increases its altitude, however, low atmospheric pressure causes engine performance to drop as drawing in high amounts of oxygen becomes more difficult. To remedy such situations, some aircraft utilize what is known as a turbocharger. As an equipment piece that pressurizes oxygen for more optimal combustion, the turbocharger is paramount to the safe and efficient operation of many aircraft. Alongside their benefits, it is also important to understand the effect that they can have on the aircraft exhaust system and how to properly care for them.
