Modern aviation has steadily shifted away from traditional electromechanical gauges that were long found in aircraft cockpits, now having embraced more efficient integrated Electronic Flight Instrument System (EFIS) technology. For pilots, aviation engineers, or flight enthusiasts, gaining a deeper understanding of EFIS components and their capabilities is essential. As such, be sure to read on as we provide an overview of these components for your benefit. Read more >>

Since the advent of flight data recorders, accident investigators have been able to help airline industries and manufacturers discover new ways to increase the safety of flight operations. First introduced in the early 1900s, flight data recorders are electronic devices that are installed within aircraft to record and collect data on many flight parameters and instructions that are sent to aircraft systems. Throughout their history, many improvements have been made to such devices to increase their capabilities and assist in investigations. In this blog, we will discuss the history of the flight data recorder, allowing you to understand how they have been developed over the years and how they are used for accident investigation.

An annunciator relay is a device used to indicate dangerous states and operating conditions in control rooms, on control panels, and in mimic diagrams. Annunciator relays feature a robust construction that ensures they are reliable and also suitable for use in harsh ambient conditions. Annunciator relays provide three distinct advantages. For one, their pre-configured messages provide time-saving startup and use. Secondly, their robust mechanical construction ensures reliable and durable ...

While aviation accidents are extremely rare in occurrence, there is always a possibility of an incident happening at some point. As such, it is important that investigators are able to properly understand the events leading up to the accident, as well as secure the data of various avionics and systems. With the flight recorder in flight management system, commonly referred to as a black box, personnel can investigate aircraft accidents during a recovery to analyse what went wron...

If you are involved or well versed in the aviation world, you may know the ATA 100 list and the various ATA codes that are included within. As a referencing standard for commercial aircraft documentation, the ATA 100 has been a useful tool for countless pilots, engineers, and aircraft maintenance technicians for a number of years. Although some may be familiar with the list itself, many may not know what ATA stands for, or may be unaware of the contents that it includes. In this blog, we will discuss the history and the incl...

One of the most important aspects of building an engine is the verification and adjustment of bearing clearance. Doing this helps establish a solid and reliable rotating assembly foundation. Unfortunately, there is no quick and easy shortcut to checking bearing clearances, but this blog will cover the basics of how to measure bearing clearance while informing you of how to avoid some common mistakes.

Most people know the difference between plugs and receptacles. In short, a plug is the “male” counterpart that functions as an electrical connection. This part is then attached to the “female” counterpart, which is called the receptacle. They can be placed anywhere where there is an electrical conductivity in the household or in the workspace. In the United States, the receptacle and plug are made up of three plugs that must be fitted into three holes. However in other countries, the plug and receptacle take different forms, which can range from two plugs to just one plug. For more information on common connector plugs and receptacles, read this handy guide below. Read more >>

With the debut and advancements of the instrument landing system (ILS), aviation navigation was revolutionized. With such guidance, aircraft are able to utilize instrument-based techniques to safely guide aircraft of all types through the approach and landing procedures, ensuring a secure and cautious touchdown during even some of the most challenging environmental conditions. In this blog, we will discuss how aircraft utilize radio technology, glide slope indicators, and other instrument...

Welding plays a central role in the construction and upkeep of many types of aircraft, particularly in vessels where strength, weight, and material compatibility need to be carefully balanced. Even as composite materials and bonding adhesives become more prevalent, welded metal assemblies remain essential to many structural and functional systems. In this blog, we will explore which aircraft components are commonly welded and how this practice contributes to reliability, efficiency, and long-term airworthiness across various platforms.

When flying in a plane as either a passenger or employee, it is no surprise to say that aircraft are very loud during their operation. When leaving an aircraft, many may be familiar with feeling ear barotrauma which comes in the form of a “clogged” sensation. This is due to a number of noises that are caused both by the aircraft, as well as from outside forces acting upon the plane. To mitigate the effects of soundproofing and protect passengers and employees from heari...
