Aircraft bearings are an essential part of countless systems and devices that are crucial for flight. They are used to keep the moving assemblies of aircraft in good working order and are in many different aircraft parts. Aircraft bearings are usually made from steel or other solid materials and are available in many different sizes. The most common aircraft bearing installation location is within a socket, allowing for flight control surfaces to be connected to the aircraft's frame. Aircraft bearings can also be installed through the staking method, that of which is used to secure aircraft parts to the aircraft's structure. Aircraft bearings are an essential part of aircraft maintenance and keep aircraft in good working order.

The buildup of ice on the wings of aircraft and other surfaces can be highly detrimental to flight, detracting from the aerodynamics of structures which can lead to losses in performance and various hazards. To avoid such issues, aircraft utilize various methods to remove ice as it forms, and such solutions are known as de-icing equipment. As there are various types of aircraft de-icing systems that can be used, each varying in its advantages and drawbacks, it can be useful to have a basic understanding of the most common forms.

As technology continues to advance over the years and more processes are automated, there is a growing worry that many positions may become obsolete as human employees are replaced by robots. Within aircraft maintenance sectors, it is a desire of many companies to ease the workload of technicians through automation, but this is not an immediate call for concern. Rather, the human component of the technician workforce is something that is not foreseen to be automated anytime soon, nor may it ever. As such, it begs the question of how technician processes can be assisted by automation for increased efficiency and accuracy.

Operating any vehicle safely, whether it be an automobile, ship, or aircraft, requires the constant monitoring of fuel levels. Airplanes, in particular, demand the most narrow tolerances with regard to operating conditions. How then can pilots have the most up-to-date information on current fuel levels? In this article, we will discuss the various fuel system indicators set in place today and how they help commercial and private aircraft operate safely.

What Are Relays?

Relays are electric switches that use electromagnetism to convert small, electrical stimuli into larger currents. The conversion is executed by activating electromagnets in an electrical input to form or break existing currents. Often found in circuits, relays are used to reduce the current that flows through the primary control switch. A relatively high capacity relay can be turned on and off by using a lower amperage switch, timer, or sensor.

Bearings are components found in countless moving assemblies, facilitating and constraining motion while mitigating friction between moving surfaces. Bearings also come in numerous types, including variations such as the cylindrical bearing, rolling bearing, plain bearing, and more. When one procures and implements bearings within an assembly, it is important that they are handled and mounted correctly for the means of protecting the bearing and ensuring that it will perform optimally. If bearings are not cared for prior to and during the mounting process, they can face excess wear and tear, presenting the possibility of part failure which can lead to assembly damage—or worse. In this blog, we will briefly discuss bearing mounting, ensuring that your bearings are implemented correctly for their optimal functionality.

Ground support equipment (GSE) refers to the various equipment at an airport that is used for servicing aircraft between flights. This equipment can range in type, many being used for ground power operations, aircraft mobility, or cargo & passenger loading procedures. Due to the roles that such equipment serve, it is important that they are well maintained and properly used to avoid breakdowns or hazardous situations. In this blog, we will discuss the basics of GSE maintenance, ensuring that you understand how to properly care for your various investments.

Before a new airplane ever makes its voyage flight, it undergoes dozens of safety tests to ensure airworthiness. Engineers endeavor to put new aircraft through all the environmental stressors it will face as part of standard operating conditions, and in addition, they push planes to their limits by subjecting them to extraordinary conditions. This blog will discuss the various stress tests aircraft must undergo before holding passengers or cargo.

An aircraft’s motion in flight is dynamic and controlled by a series of different parts. Unlike other modes of transportation, airplanes move in a three-dimensional plane. The three axes that an aircraft can rotate in are yaw, pitch, and roll. Movement on any axis will shift the center of gravity and require a counter-movement to maintain a level and comfortable flight. While pilots manipulate many different aerodynamic devices to maintain level flight, this blog will focus on an often overlooked part called the rudder.

Before flight and after takeoff, it is imperative that all aircraft undergo appropriate anti-icing and deicing measures to circumvent the buildup of ice when exposed to freezing temperatures. As certain aircraft are predisposed to accumulating more ice than others due to their shape and operational factors, certain items composing an aircraft require additional attention to detail upon construction to mitigate complications caused by ice accumulation. As ice can rapidly form on all areas of an aircraft, including the engines, ice protection systems are critical for the following systems of an aircraft: wings and aerofoils, power plants, high lift devices, control systems, and ice protection systems. Within this blog, we will discuss the fundamentals behind the basic operations of deicing and anti-icing systems and why they are crucial to ensuring passenger safety and vehicle stability.

While supplemented oxygen is necessary when flying at high altitudes, have you ever considered how breathable air is provided to the cabin? Within most commercial aircraft, air is divided equally between two ratios: recycled air and bleed air provided by the engine or auxiliary power unit (APU). Before this air can be circulated to the cabin and exposed to passengers, it must first undergo filtration to ensure quality, breathability, and comfort. As an installed feature among many fixed-wing aircraft, high-efficiency particulate air (HEPA) systems ensure circulating air is not only free from pollutants, but also help protect against dust, dirt, fibers, microbes, allergens, and more. Within this blog, we will go over the fundamentals of cabin air filters, how they are constructed, and why they serve a large role in keeping the cabin and crew safe.

In aircraft systems such as the engine, lubrication serves to protect moving assemblies through the reduction of friction and heat. No matter how thorough or precise the manufacturing process is, there will always be microscopic imperfections on assembly surfaces that can break or seize when coming into contact with other irregularities. Beyond damaging the surface of a particular component, broken off pieces may continue to flow through a system, resulting in more wear and tear to various structural parts. To prevent these hazards from affecting the service life of a particular assembly, it is important to properly implement and manage lubrication on regular intervals.

Whether an aircraft is preparing to take off, is in cruise, or is about to land, pilots are regularly in communication with individuals outside of the aircraft for safer and efficient operations. While talking over the phone in an automobile is an illegal act that is quite dangerous, communication during aircraft operation is paramount as it allows for the pilot to safely conduct their operations without the risk of running into other aircraft or other hazardous situations as they communicate with air traffic control and others. From traditional radios to up and coming communication devices, there are numerous ways in which pilots can communicate with others.
