In the realm of aviation, stalls are caused when lift is quickly replaced by turbulent drag. Aviation stalls are not to be confused with a mechanical problem such as a stalling aircraft engine as aircraft stalls are caused by too high of an attack angle at a slow speed. When the angle is exceeded, airflow from the upper surface of a wing separates, causing a loss of lift and thus a loss of altitude. While pilots are trained on stall situations and how to pull out of them, there are also many technologies that have been designed over the years to help prevent stalling, give warning to the pilot, as well as provide characteristics of the stall that are easier to pull out of. In this blog, we will give an overview of a few of the more common types of devices that provide favorable stall characteristics.

According to the Code of Federal Regulations (CFR), people may not legally operate an aircraft that has not been deemed airworthy. From required annual inspections to approval of parts for maintenance, aircraft and their parts undergo many certifications and inspections to ensure that they are airworthy and legal for use. While it may be simple to understand the reasons we demand that aircraft are airworthy, the details in what qualifies a part as “airworthy” can be complicated. With many set regulations in place, what makes an aircraft part considered airworthy?

Aircraft inspections, maintenance, and overhauls are by necessity a lengthy and involved process. Even the simplest procedures must be inspected and verified to ensure that the aircraft is airworthy before being returned to the owner, a process that can last weeks or months if done inefficiently. To avoid costly delays, here are five tips for when you’re planning an aircraft repair, inspection, or overhaul job.

A critical part of pre-trip planning is aircraft support equipment and supply considerations at the airport you will be landing at. When operating from remote or secondary/domestic airports, you may face supply restrictions or equipment shortages you would not encounter at larger airports. This checklist includes some of the most critical issues you should make sure you address before setting out.

There comes a point where the maintenance of an aircraft is simply not worth the cost. Instead of spending tens of thousands of dollars replacing an engine component or flight instrument, many aircraft owners and operators choose to turn the aircraft over to salvagers.

A pressure sensor is a device equipped with a pressure-sensitive component that measures the pressure of a gas or liquid and converts the measured value into an electrical signal as an output. These are also referred to as pressure transducers or pressure transmitters and are used for controlling and monitoring pressure. Their day-to-day usage includes biomedical instruments, touch screen devices, and automobiles. Pressure sensors can also be used to measure other variables such as water level, altitude, and speed.

Connectors are one of the most common electronic parts in the market. Because there is such a wide variety of connectors and applications for these connectors, it can be difficult to know what you need for what purpose. Fortunately, the most common types of connectors are relatively easy to recognize.

IBM sold its first personal computer in 1981 which was an impactful moment in computer motherboard history. It included a planar board, which featured an Intel 8088 central processing unit (CPU), built-in memory, and external input/ output (I/O). This was a huge upgrade compared to the previous motherboards— they were large and clunky. Creating compact and advanced motherboards allowed computers to become lighter and more sophisticated.

Most aircraft utilize hydraulic systems, some more complex than others. These systems function using pressurized fluid based on Pascal's Law, which states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions such that the pressure ratio stays the same. The main components found in these systems are reservoirs, pumps (i.e. vane and spur gears, fixed angles), pressure regulators, accumulators, valves, and actuators and filters.

If you like video games, you're probably like the rest of us and you can't stand to play a graphics intensive game with anything less than 75% resolution, even if you were willing to sacrifice resolution for fps (frames per second). After all, playing with low resolution means that you're missing out on a lot of details. But, what can you do? The graphics card determines how well your computer processes images, and a bad graphics card means a poor gaming experience. So, if your graphics card is outdated, it might be time for an upgrade.
