Aircraft are made from millions of individual items, and as knowledge is key, it is best that pilots familiarize themselves with how various systems and assemblies function on board the vehicle. In particular, as the function of engine mechanics may only be briefly reviewed in rudimentary flight training, a pilot should still take the time to study various aircraft engines and the parts that construct them; in the future event regarding engine issues while in the air, this information can aid pilots in determining the best course of action.
Aircraft corrosion is a persistent problem for aircraft operators. Corrosion deteriorates the aircraft structure and its internal components, making it dangerous to operate and expensive to repair. More than that, there is no real way of reversing the effects of corrosion, which can make aircraft inoperable in just a matter of years.
Many aircraft feature propeller assemblies that are used to generate the thrust necessary for flight, and it can be highly beneficial to understand how such processes work. Just like the wings on each side of the fuselage, propellers operate on the principle of lift, manipulating the flow of air to adjust air pressure for forward propulsion. In this blog, we will discuss propellers in more detail, allowing you to have a better understanding of their functionality and the method in which thrust is produced.
Automotive relays are switches that turn electrical circuits on and off. They come in different shapes, sizes, and can be found in cars, gas valves, alarm systems, and more. Relays are typically used to enable a low amperage circuit to switch a high amperage circuit on or off. Relays can also be used to switch multiple things at the same time with the use of one output. When a single output is connected to multiple relays, you are able to simultaneously open continuity and/or close continuity. In this blog, we will be covering how automotive relays work and their circuit design to better understand these helpful devices.
In the world of aviation and aircraft safety, some things never change.

A full authority digital engine control (FADEC) is a system consisting of a digital computer, known as an electronic engine controller (EEC) or engine control unit (ECU), and its related components that control all aspects of an aircraft’s engine performance. FADECs are used in both piston and jet engines. In this blog, we will discuss FADEC’s functions and advantages in detail.
Throttle hold is a flight mode for remote control (RC) aircraft. It is controlled by the throttle hold switch which, when activated, controls the throttle at a pre-set percentage of engine idle, regardless of the collective pitch stick position. It is used to practice autorotations, and as a safety measure to help prevent accidental spool up, wherein the rotors of the helicopter begin rotating unexpectedly. Throttle hold can also help minimize damage after a crash. In this blog, we will discuss the benefits of throttle hold.
The thrust management system (TMS) is a part of the aircraft’s Flight Management System, and it allows for pilots to set computerized control over throttle. Similar to the cruise control systems commonly found in automobiles, such devices can increase the efficiency of flight operations for the benefit of pilots. Furthermore, such systems may also be advantageous for safety reasons as well, making them useful for pilots and aircraft. In this blog, we will discuss thrust management systems, allowing you to better understand how they are used and what functions they can provide.
The onset of the COVID-19 pandemic disrupted nearly every industry around the world. Aviation was no different, and, in fact, was one of the most harshly affected industries of all. Flights were canceled, traveled restrictions were imposed, and companies felt the effect. This has led to two main problems: a significant drop in fuel demand & fuel price, and the problem of storing all the grounded aircraft. Within the field of aviation, the jet fuel market has been by far the hardest hit. Although a vaccine is on the horizon, it is expected that the demand for jet fuel will remain low into the near future. As low demand for flights leaves many companies struggling to survive, the aviation jet fuel market could take years to recover....
While aircraft contain a plethora of advanced technologies and systems that have made flight one of the safest methods of traveling by far, there are still incidents in which they face tragic accidents.

Cosmic ionizing radiation is a form of ionizing radiation that comes from outer space. A very small amount of this radiation reaches the earth and at flight altitudes, passengers and crew members are exposed to higher levels of this radiation. The World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) inform the public that ionizing radiation may cause cancer in humans and is also known to cause reproductive problems such as miscarriages and birth defects.
The nature of air travel means that aircraft have to be able to withstand a myriad of conditions both light and extreme. Something no aircraft wants to go up against is lightning, but air travelers expect a hassle-free experience, and delays or cancellations are only an option in the most extreme conditions. Lightning, while not ideal, is not necessarily cause for grounding an aircraft. Instead, aircraft manufacturers take measures to protect their machinery from the elements.....
If you’ve ever boarded an airplane from outside the terminal via a ladder, you might have been close enough to see the engines of the plane. Upon closer inspection, you might notice that at the center of the engine point is a depiction of a spiral, which spins and eventually turns into a white spinning symbol once the engines start spinning at full speed. Sometimes the symbol doesn’t resemble a spiral, rather it looks like a comma, or a typhoon symbol, or even a wobbly crescent. Sometimes you’ll see that there is no symbol at the center of the spiral. But what significance do these symbols, if present, have?
From takeoff to landing, all aircraft require some sort of electrical power for important functions such as navigation, intercoms, COM and NAV radios, and more. With in-flight entertainment and increasingly modernized systems, this need for electricity is ever more present. To get power, aircraft often use electric power generation through generators and alternators. Both of these systems produce power for the aircraft but differ in method, as well as have various benefits and drawbacks when compared to each other.
The aircraft electrical system is a network of components that transmit, distribute, and store electrical energy. Most modern aircraft have a 28 volt direct current electrical system, which typically consists of a battery, the master switch, alternator, an ammeter and a loadmeter,. Through the electrical system, the aircraft’s taxi lights, landing lights, radio equipment, interior cabin lights and other equipment are supplied with power. For a detailed look at some of the important components and the roles they play, read below:
In aviation, each piece of machinery has an important role. Parts need to be tough and dependable to put up with the rigors of air travel.
