For an aircraft to remain airworthy and safe to operate, it must meet stringent quality guidelines and regulations that focus on part conditions, maintenance, and approval. To prevent damage to various parts and systems and their subsequent failure, aircraft engineers take advantage of a process known as heat treatment. Generally, this process will cover a wide variety of parts ranging from landing gear components to the individual bearings and joints of assemblies, ensuring that they all perform with high reliability and integrity. In this blog, we will discuss the heat treatment of aircraft components, allowing you to better understand how such processes are carried out for a number of items. Read more >>

For airlines that require high amounts of power for their standard set of operations, having a device that provides energy for functions outside of propulsion can be highly beneficial. Common to large aircraft such as commercial airliners, devices such as Auxiliary Power Units (APU) are regularly used for the vehicle to operate autonomously without the aid of a ground power unit, high pressure air start cart, external air conditioning unit, or other various ground support equipment. In this blog, we will discuss the design and operation of auxiliary power units, allowing you to better understand how they augment the operations of various aircraft. Read more >>

Aircraft lighting is a crucial aspect of flight safety, ensuring that pilots and passengers have the ability to see their surroundings to safely move around a cabin, interact with controls, and more. Aircraft cockpit lighting and panel lighting solutions in particular serve an extremely important role, providing pilots visibility to efficiently operate and monitor all aircraft instruments, switches, breakers, and more. In this blog, we will discuss the main aspects of aircraft cockpit lighting, allowing you to better understand how pilots maintain safety and control during low visibility conditions and night operations.

Aircraft landing gear can come in a variety of forms, the most common being those that utilize wheels. With a tire and wheel assembly, the entire weight of an aircraft can optimally be supported during takeoff, landing, and taxi procedures. To ensure that even the most massive commercial transporters are supported, wheels are engineered to be extremely strong, yet lightweight. To best understand how the tire and wheel assembly efficiently provides for aircraft ground procedures, one must learn how they are designed and how they function. Read more >>

Preparing for numerous possible weather conditions is a crucial part of flight planning, and it allows for operators to ensure that flight paths can be optimally made using the most efficient and safe routes. Turbulence is one of the most impactful forces on aircraft parts, often accounting for upwards of $100 million annually for the maintenance and efficiency impacts faced by the general aviation sector in the United States alone. To create optimal flight paths while accounting for weather, technology has consistently advanced to increase the capabilities of weather systems for more accurate and real-time forecasting. In this blog, we will discuss the future of weather systems and how upcoming technologies will improve flight planning. Read more >>

A transponder is a wireless communications, monitoring, or control device that picks up and automatically responds to an incoming signal. The term is a contraction of the words transmitter and responder. An aviation transponder has multiple interrogation modes, or formats of pulsed sequences from an interrogating Secondary Surveillance (SSR) or similar system. Multiple modes exist, such as modes 1-5 for military use, and modes A-D for civilian use. In this blog, we will discuss everything you need to know about mode C transponders. Read more >>

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...
