Many who have ridden within an aircraft are familiar with the various types of interior lighting typically featured within interiors and cabins, those of which play important roles in enhancing safety, comfort, and functionality for passengers and crew members alike. Despite this, fewer may be aware of the diverse array of lighting systems integrated into the exterior of a typical commercial aircraft, each having a critical function in facilitating safe operations in the air and on the ground. In this blog, we will examine the main types of external lighting systems that are present on aircraft, providing a basic overview of their distinct design features, operational roles, and regulatory importance.

Ensuring passenger and crew safety in routine operations and emergencies where controlled cabin air is unavailable is important in modern aviation. As aircraft climb to cruising altitudes, atmospheric pressure and oxygen levels decrease significantly, so reliable systems are often needed to provide breathable air. This blog explores some notable types of oxygen delivery systems, highlighting how they function, where they are used, and the advantages and challenges associated with each one. Read more >>

Aircraft interior cleaning is a critical procedure that ensures a safe, hygienic, and pleasant environment for passengers and crew members alike between commercial flight operations. Given the confined space and high frequency of use in commercial operations, the interior of an aircraft can quickly accumulate dirt, germs, and wear, making regular cleaning essential. In this blog, we will go over the detailed and systematic approach taken to maintain the cleanliness and functionality of various components within an aircraft. Read more >>

In mechanical engineering and machinery, the terms "bearings" and "bushings" often emerge in discussions surrounding the reduction of friction between moving parts. Despite their shared goal of minimizing wear and facilitating smoother motion, these components possess distinct characteristics, applications, and design intricacies. This blog post aims to shine a light on the differences between bearings and bushings to provide a comprehensive understanding that is both professional and accessible. Read more >>

Gas turbine engines play a central role in modern aviation, powering numerous aircraft across the skies. However, these engines depend on a critical component known as the ignition system to function effectively. In this blog, we will discuss the basic components and working principles of aircraft gas turbine engine ignition systems so that you can have a better understanding of them. Read more >>

To control an aircraft's various systems and functions, different technologies have been employed to manage these larger-than-life vessels. Since the advent of aircraft control systems, maneuvering an aircraft has never been easier. In fact, aircraft control systems play a crucial role in ensuring the safe and efficient operation of airplanes. To better understand how they work, we will explore and compare three common types used in aircraft: hydraulic systems, cable systems, and fly-by-wire systems. Read more >>

To ensure that your aircraft remains airworthy, preventative maintenance and inspection is necessary, and since the Wright brothers first took flight in 1903, several improvements have been made to such processes. For instance, the corrosion resistance of aircraft has been enhanced by improving materials, surface treatments, insulation, and protective finishes, and these changes have been aimed at reducing the overall maintenance effort required while boosting reliability. Despite these improvements, the control of corrosion requires continuous preventative maintenance. Read more >>

In the aviation industry, there are numerous standards, criteria, and approval processes that aircraft parts are subjected to. Because aircraft operate under a wide range of environmental conditions and are expected to endure various stressors, the parts and components they are composed of must meet certain compliance measures. However, aircraft parts can be divided into several categories based on how they are manufactured. Read more >>

When encountering freezing temperatures, it is imperative that all aircraft undergo appropriate anti-icing and deicing measures before takeoff to circumvent the buildup of ice. As different aircraft—such as commercial jets—are predisposed to accumulating more ice than others due to their shape and operational factors, certain items composing the vehicle require additional attention to detail during construction to mitigate complications caused by ice. As ice can rapidly form on all areas of an aircraft, including the engine(s), ice protection systems are critical for the following parts of a plane: wings, aerofoils, power plant(s), high lift devices, and control systems. Within this blog, we will discuss the fundamental basics of deicing and anti-icing equipment, and why they are crucial for ensuring passenger safety and vehicle stability.  Read more >>

Printed circuit boards, or PCBs, are a common element of countless electronic systems. Coming in the form of a flat substrate with various embedded electronic components and copper traces, PCBs act as a medium that collects and connects components to one another in a very controlled manner. While a majority of circuit boards perform the same roles, their exact makeup and design will differ based on the application and environment in question. For example, many modern aircraft that are highly electrified take advantage of printed circuit boards for standard system functionality, but unlike the PCBs that may be found in a home computer, these boards must be rigorously designed to withstand the demanding needs, intensive stresses, and environmental conditions present during flight.
