In order for pressure gauges to continuously provide accurate readouts, they must be regularly calibrated using the correct technique. Although calibrating these precision gauges takes time and involves thorough attention, it is entirely necessary to avoid costly errors. Whether you are an expert in this field or have never worked with pressure gauges before, it is beneficial to review the essential details associated with the calibration process. In this blog, we will discuss everything you need to know when it comes to pressure gauge calibration.

When it comes to aviation safety, every event, from taxiing to parking the aircraft, should be treated with an equal amount of respect and attention to detail. While most consider the flight to be over as the plane approaches the apron, mistakes involving the parking brake may result in significant damage and expenses. Although the majority of aircraft use chocks placed by ground crew members to park the vessel in the correct place, there are several circumstances where the tarmac is off-limits for personnel. Additional cases where parking brakes are employed to maintain aircraft position include deicing, ramp holds, and emergency stops. In this blog, we will detail the design and function of the parking brake in order to give you a better understanding of this often unappreciated component.

When a pilot is operating an aircraft, there are various flight conditions that they must keep an eye on for safety and efficiency. One of the most important values to know during flight is one's altitude, that of which is the distance of the aircraft in relation to the ground below it. There are various ways in which altitude may be measured, one common way being the use of an aviation radio altimeter, or aircraft radar altimeter. With a radio altimeter, the distance between the aircraft and the terrain below can be determined with ease, allowing a pilot to conduct a safer landing in low-visibility conditions. In this blog, we will discuss the functionality of a radio altimeter and its design, allowing you to better understand how such devices are used.

Avionics, or aviation electronics, are devices and systems implemented in aircraft to replace the traditional mechanical and analog equipment used by pilots. With avionics, the flight crew can execute an operation safely and efficiently, regardless of whether a mission is to transport passengers between destinations or intercept a hostile aircraft. There are many reasons as to why avionics are advantageous, examples including their offered safety, all weather options, fuel reduction capabilities, improved performance and handling, and much more. To help you become more familiar with avionics equipment, we will cover the most common types that are found in most aircraft.

Auxiliary power units (APUs) are electrical power and heat sources used in mobile systems and operate independently from the main engine that is responsible for propulsion. Some of these mobile systems include passenger cars, buses, trucks, ships, and aircraft. Within aircraft, APUs generate on-board electricity for air conditioning and other related systems, especially during on-ground, and take-off procedures.     

A threaded insert, or threaded bushing, is a fastener component that may be installed in the surface of a component for the means of establishing a threaded hole. While threaded inserts may commonly be used for threaded hole repair, they may also increase the durability of softer materials, enable holes to be established in thin materials, avoid machining requirements, or be used to shift between unified and metric threads. In order to optimally install such components, a tool known as a threaded insert riveter is commonly used.

A typical aircraft will contain a plethora of fasteners, each specifically employed for varying means such as securing components, installing assemblies, and much more. Dzus fasteners in particular are common to aircraft construction, and they are regularly implemented for the means of attaching removable skin panels onto aircraft and other high-performance vehicles. As Dzus fasteners present an ease of installation for aircraft fixtures, understanding their use and common types can be helpful when searching for the right fit for a particular application.

A rechargeable battery is a type of electrical battery that may be discharged and recharged multiple times, rather than serving as a one-time use power source. As a common component of countless electronic devices, electric vehicle systems, and aircraft, it is important that rechargeable batteries are well managed and protected to ensure their continued efficiency and functionality over many cycles. With a device known as a battery management system (BMS) a rechargeable battery may be managed for the means of protection, monitoring, control, and more.

While there are various aircraft that may be unpressurized, the majority of commercial airliners and business aircraft will utilize a pressurization system for the benefit of passengers and crew members. At the high altitudes that many aircraft operate at, the presence of low air pressure can result in insufficient oxygen density that is hazardous to individuals. While an oxygen tank may be used to combat this, such solutions are not efficient for aircraft in which many individuals are aboard. As such, the pressurization control system is implemented for numerous aircraft in order to protect all individuals from hypoxia.

Resistors are electronic devices that are designed to impede the flow of current running through their bodies, allowing for the protection of sensitive electronics while also opening up the opportunity to control and manage voltage values for specific applications. As a technology that was first invented in 1959, resistors now serve almost all electrical circuits. With a variety of resistor types featuring different constructions, materials, tolerance values, and other characteristics, finding the correct type often depends on the specific needs of the operation. In this blog, we will discuss the carbon film and metal oxide film resistor in particular, allowing you to best understand the differences between two very common electrical circuit components.
