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.

Plain bearings, otherwise known as bushings, are a type of mechanical elements that are used in machinery to provide a bearing surface that reduces friction between rotating shafts and stationary support while still offering support and bearing the load. When buying bushings, it’s important to know what types of bushings serve what kind of purpose best.

As engines get older, the risk of overheating increases. If an engine overheats, it can cause it to "blow" rendering it out-of-commission. Thermostat housings act as a cooling outlet for internal combustion engines. Coolant flows through internal ports, traveling through the engine block and cylinder head parts. From there the coolant reaches the thermostat housing, goes into the radiator, and is finally cooled.

Good news for the iPhone-obsessed: Apple has a next-generation iPhone SoCs in the works!  The A12 chip is now in production, and the CPU core will be built on TSMC’s 7-nanometer design. TSMC first announced they were in mass production back in April but did not disclose who they were building them for specifically.  Since Taiwan Semiconductor Manufacturing Co (TSMC) is Apple’s preferred manufacturing partner, one could safely conclude that it is being made for Apple’s iPhones. Apple switched to the Taiwanese company after previously utilizing Samsung for the 14nm node.
