When operating an aircraft, it is always important to ensure that every system and component is well maintained to preserve airworthiness and safety standards. The aircraft jet engine in particular is a section that requires thorough maintenance as the extreme conditions that aircraft undergo during flight operations can cause damage and inevitable failure if left unchecked. In this blog, we will discuss why jet engine maintenance is important, how it is conducted, and more. Read more >>

ADS-B technology (Automatic Dependent Surveillance Broadcast) is a rising solution in the world of aircraft control. It combines GPS, satellite, and computer processing capabilities with the goal of gradually phasing out the reliance on radar, a longtime cornerstone of aviation navigation. Instead of traditional radar, the ADS-B system determines its position via satellite navigation and broadcasts it, allowing it to be tracked. The information is received by air traffic control ground stations as a replacement for secondary surveillance radar, as a ground-based interrogation signal is not needed. Read more >>

The new normal is a phrase that has cropped up numerous times this year and in the current COVID 19 climate, it’s no surprise to anyone. The new normal is a phrase that describes a world with a new set of commonalities. Masks is the best example of this, but so are things like ventilators and respirators. These words are being used several times a day in teh news and in some sectors, every language. If you’re not familiar with what a ventilator or a respirator are, read on below. In this article we will discuss the two and describe their similarities and their differences. Read more >>

Pressure transducer, pressure transmitter, and pressure sensor are often used interchangeably. This is not entirely correct. First, let’s look at the differences between pressure transducers and transmitters. In its most basic form, a transducer is a device used to measure pressure, load, force, or other factors, and convert the reading into an electronic signal. A transmitter also converts a reading into an electrical signal, but subsequently amplifies, modifies, and sends the signal to another receiver. Read more >>

A hard disk drive (HDD), otherwise referred to as a hard drive, serves as the data storage device of a computer. HDDs are considered a “non-volatile” storage device, meaning that the data stored on them will not be lost when they are powered off. Since their advent in 1956 by IBM, HDDs have served as the main storage device for personal computers and servers. Recently, however, the growth of solid-state drive (SSD) technology has sought to disrupt this growth. In this blog, we will discuss how a hard disk drive works, as well as how hard disk drives and solid state drives compare to each other. Read more >>

A radio altimeter is an electronic device that measures the altitude of an aircraft above the ground immediately below the aircraft. It determines the altitude by sending a radio signal from the aircraft to the ground where it reflects and travels back to the aircraft. The altimeter makes note of the time it took the signal to travel to and from the aircraft and converts that into a figure representing the altitude. The altitude measured by the radio altimeter is called “absolute altitude” and refers to the constantly changing measurement of the distance between an aircraft and the ground. The speed of the radio altimeter’s signal is necessary to provide the pilot with real-time readings of altitude. Read more >>

For any engineer or manufacturer, the concept of “the perfect invention” does not exist because anything that is produced always has the potential to be further improved. This is the kind of mentality that exists among aviation manufacturers, with particular regard to those in the avionics test equipment industry. This sector is an especially stringent one because any new test equipment that is released in the market is expected to have the latest technological advancements, while also possessing the capabilities to test various types of aircraft components, both new and old models. This is just one of many complications that those in the sector face. Below you can read more about some of the challenges encountered by the avionics test equipment industry. Read more >>

A necessity in many industries, pressure transducers measure pressure and create an electrical output proportional to the input. This is done by using variable pressure sensors to measure deflection and resistance and transform that pressure into either a voltage, current or frequency.The sensing element or diaphragm is deflected due to input pressure and moves in relation to a resistor or capacitor plate that then sends an output signal based on the varying tension received by the input pressure. Most types of transducers require an electrical input called an excitation. Transducers typically produce one of three types of output: millivolt (mV), voltage (V), and milliampere (mA).
