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.

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 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. Across most accidents that occur within the commercial aviation sector, a majority are due to human error. Human error can cause many types of accidents, ranging from a miscalculation by a pilot to incorrect directions provided by an air traffic controller. As one of the three primary causes of accidents, incorrect or poor aircraft maintenance can result in a variety of issues that can lead to dangerous situations. On top of presenting a safety risk, negligent maintenance can also cause delays, financial burdens, and other issues for the airline or aircraft operator. As such, being more on top of maintenance scheduling and ensuring that procedures are carried out correctly is paramount to the safety of an aircraft.

Most people have used autopilot in a car and feel comfortable with using it. When discussing aircraft, however, many people might cringe at the thought of an aircraft pilot using autopilot. However, what many people do not know is that it is quite normal for technologically advanced planes, particularly bigger business aircraft to have an autopilot framework. Regardless of whether you're new to the mechanics behind autopilot frameworks, you're likely very much aware of the important reasons for pilots to choose to use an autopilot system. They do it to control the plane with practically zero requirement for human navigation. It's an inventive and convenient element that takes a portion of the weight off the pilots' shoulders. With the autopilot turned on, pilots can concentrate on different parts of the flight, for example, observing climate, direction and that's just the beginning. For more information on how the autopilot system works and how it benefits the pilot and cabin crew, read on below.

Aluminum was once the primary material used in aerospace applications. However, in modern jet aircraft, it accounts for just 20% of the construction. However, because of the demand for lighter weight aircraft, composite materials such as carbon-reinforced polymers and honeycomb materials continue to increase in usage across the modern aerospace and aviation industries. Further requirements such as the need to withstand high temperatures, pressures, and corrosion have paved the way for other materials once considered impossible for use in aerospace. One such material is stainless steel, which has seen increased usage in newer aircraft components.This blog will explain uses of and differences between aluminum and stainless steel in modern aircraft.

Electric airplanes could change the manner in which we travel. Along with a significant decrease of CO2, electric aircraft would also bring about a decrease in sound contamination, and with no requirement for air terminal runways, we'll see a lot increasingly downtown air terminals, combined with less flying limitations. Electric planes truly can possibly change the manner in which we work, travel, and live. For example, numerous individuals need to live in the open country, however are denied by an absence of business. Electric aviation would empower them to drive, by means of air, to neighborhood urban communities for work. Inside urban areas themselves, it would encourage short excursions utilizing 4-6 seat taxi planes – making it simple to rapidly make a trip from south to north London, or from San Francisco to Palo Alto, for instance.

Aircraft hangars are just as common as aircraft themselves. Anywhere you see aircraft, odds are there is a hangar not too far away. Apart from storage, hangars serve a crucial purpose in the aviation industry: maintenance. Maintenance hangars differ significantly from a line or storage hangar. Traditional hangars have a simple function: to house aircraft safely and securely. On the other hand, maintenance hangars are broad, wide-open arenas with the lone purpose of conducting major maintenance, repair, and overhaul (MRO) on aircraft....

Landing gear is an integral part of any aircraft, and perhaps the most important part of landing gear is the struts. The struts are the piece of equipment that bears the brunt of the force an aircraft experiences when it touches back down on ground after flight. Struts ensure that even a rough landing doesn’t cause serious damage to your entire plane. There are four common types of landing gear struts: rigid struts, springs steel struts, bungee cord struts, and shock or oleo struts...

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.
