Most people are familiar with memory cards, which are small flash drives commonly used in phones and digital cameras. Also known as flashcards, they are able to store media and data files permanently and are intended for primary, portable memory in devices such as phones, cameras, and other handheld equipment. There are many types of memory cards, including Secure Digital (SD) cards, CompactFlash cards, SmartMedia, Memory Stick, and MultiMediaCards, so it can be useful to understand the different uses for each.

As a passenger on a commercial flight, you may have noticed the dimming of the cabin lights both before takeoff and in the final moments of descent before landing. This procedure not only happens in the cabin, but also in the cockpit as part of an important safety measure for all on board. If you are curious as to what dimming the lights has to do with safety, read on as we discuss why this simple procedure takes place on commercial flights.

A power supply is a device that is used to convert the electrical current that enters from a power source to the voltage and current values necessary for powering a load. In electrical systems, the load is a device which consumes electrical energy in the form of current and transforms it into other forms like heat, light, work, etc. A power supply must transfer current in a controlled manner to a wide range of loads, sometimes simultaneously, all without letting changes in the input voltage or other connected devices affect the output. A power supply can be external, such as charging devices for a laptop computer, or internal, as in larger devices like desktop computers. Furthermore, a power supply can either be regulated or unregulated. In a regulated power supply, the changes pertaining to the input voltage do not affect the output, whereas in an unregulated power supply, the output depends on the input.

When discussing any form of unmanned or remote-controlled aircraft, many are all too quick to label them as a aircraft drone. While the term “drone” has now been widely adopted, it can become confusing when the same term used to describe a simple hobbyist option is also used to refer to a high-tech military weapon used on the battlefield. Each of these varying “drones” has its own name, and such aircraft may come in the form of a UAV, UAS, RPA, and more. In this blog, we will provide a brief overview of the most common types of aircraft that fall under the drone umbrella, allowing you to better understand the differences between each.

While an aircraft is traversing the sky, it must be able to maintain communication with ATC operators, collect important weather and global positioning data, receive internet connectivity for crew and passenger use, and much more. All of these functions are made possible through the use of various antennas that are situated across the body of the aircraft, each of which serves a unique function. In this blog, we will discuss the various aircraft antennas that are featured on modern aircraft and their individual functionalities.

An aircraft alternator is a piece of electrical equipment that supplies the aircraft with the necessary power to operate optimally. A malfunctioning alternator prevents an aircraft battery from charging properly, which can leave a pilot grounded until the issue is resolved. Such situations are less than ideal for passengers and aircrew that cannot afford delays or setbacks.

The airframes of aircraft are assembled and held together with the help of different types of fasteners. When building an aircraft, it is very important to choose the correct bolts, as they are responsible for holding the entire airframe together and a lot is at stake. Bolts fasteners that are designed for holding two or more parts together. In this blog, we will discuss what should be taken into consideration while choosing the right bolts.

Aircraft expertise, quality work, and high capabilities are crucial while repairing an aircraft engine. Most repair facilities do not discuss intangibles, but these items can impact a successful repair project and costs. Without an inspection of the engine prior to the quotation process, it will not be easy to estimate an accurate repair cost. Debris-related problems are not the same as the routine planned removal, and different repair operations can widely vary in price. As such, it is important that aircraft mechanics and engineers define prices with ample information on a need.

Potentiometers are a type of three-terminal resistor, featuring an adjustable tapping point that allows a device to act as an adjustable voltage divider with variable potential. Potentiometers can come in various types to accommodate different applications, each differing in its design and functionality. Trimpots, otherwise known as trimmer potentiometers, are specialized potentiometer devices that are used to adjust, tune, and calibrate electrical circuits. As components that are common to a number of electrical applications and systems, it can be useful to have a basic understanding of the trimmer potentiometer.

A reed relay is a type of relay that utilizes an electromagnet to control one or more reed switches. Consisting of a reed switch, a coil, optical diode, and connection terminals, reed relays are devices with a low-resistance metallic switch path that provides an inherent isolation between the control voltage operating the coil and the signal being switched.
