Maintaining an aircraft is far more than washing the exterior and cleaning up the interior of the cabin. The maintenance cycle can be defined by various levels, each named with an alphabetical letter in progressing levels of complexity. Check A is the most routine, taking no more than an hour or two. Check C on the other hand, is a far more extensive checking of independent aircraft components, functions, tooling, and equipment.
Have you ever looked down on a city from a vantage point and marveled at all of the tiny little buildings below, interconnected by intricate streets and sidewalks? Each and every building serves a purpose. The streets that intertwine the city allow people to travel from one part to the other, making all the buildings accessible. The way cities are arranged, their interconnectivity, and their accessibility all contribute to the vibrancy of it and make it so much more than the sum of its individual parts. The same concept can be applied to electronic equipment.
The aerospace industry in the United States is highly regulated in all areas. Whether you’re flying in a trainer aircraft, commercial airliner, or military aircraft, each of them has gone through a series of tests to become certified as airworthy. In comparison to civil and commercial aircraft, military aircraft are subject to faster speeds, extreme temperatures, and quick maneuvers. As such, military parts require particularly complex standards due to them. nature in which they operate. The military will only allow the best products to be used on their aircraft— and there is no room for error Regulations cover everything from the nuts and bolts used on an aircraft to the main structural components. Electronics, wires, cables, seatbelts, etc., are all well-regulated.
Both delay-on-make timers and delay-on-break timers are classified as time delay relay systems. In other words, these components are considered control relay devices with time delay functions built in. Though both mechanisms are not typically noticeable, we see them quite often in everyday life. When you step through a door and a fan overhead turns on, you’ve activated a delay-on-make. If you’ve adjusted a thermostat or air conditioning system, you have encountered a delay-on-break. Electronic parts manufacturers label both systems under the same umbrella because the processes of these electronic part types are essentially the same, but the results differ.
When buying electronic parts, there are many factors to consider. It’s important to be able to find the aviation components you need without unnecessarily overpaying, and to be sure you are purchasing the right product.
The first step is to search the market for pricing, availability, and lead times if the product is out of stock. The most efficient way to do this is to use aggregator websites. Here, potential customers can see distributors’ listings and compare prices and availability all on the same site. It’s much more efficient to use these types of sites rather than Google, because you can find many electronic parts distributors who stock the part without going back and forth between the multiple sites Google generates. Not to mention, Google search results are not always reflective of popularity or relevance thanks to features such as Google Ads.
The most important part of an aircraft engine, arguably, is the lubrication system. But it’s also the most vulnerable. Generally, lubrication systems are recirculatory. Fresh oil is introduced to the lubrication system and met with bearings, seals, and gears that wear and erode, producing abrasive contaminants. The oil flushes them away and carries them to the scavenge oil flow away from the sump where they are almost completely filtered out.
In an interview with Hush-Kit, the alternative aviation magazine, Bing Chandler, a former Lynx Observer from the Joint Helicopter Command and the British Army Air Corps Center, talks about his top 10 attack helicopters.
The structure of aircraft has changed enormously over the last century, with most changes being made to aeronautical engineering. Almost every aspect of creating and designing an aircraft has changed. Changes have been made to aerodynamics, engineering, navigation aids, interior fittings and structural design. The first successful flight conducted by the Wright brothers was powered by a small light engine that wouldn’t weigh down the structure of the aircraft itself. The first jet engine, a heavier type of engine, was created and used during WWII. Since then, the structure of the aircraft has completely changed and is still changing today.
UTC Aerospace Systems (UTAS), operating under United Technologies, is one of the world’s largest suppliers of aerospace and defense products. UTC develops, manufactures and delivers parts to some of the biggest names in the aerospace industry. As a premier Boeing parts supplier and Airbus parts supplier, UTC has been hit hard with increases in production rates demanded by these OEMs.
UTC’s CEO, Greg Hayes, said during the company’s first-quarter 2018 earnings call,
Printed Circuit Boards (PCBs) are the foundation for everything electronic. As we move further into a technology-dependent society, everything is becoming digitized- which in turn increases the demand for PCBs. According to TechNavio, a leading market research company, the worldwide PCB is forecasted to grow at a rate of 6.14 percent from 2017-2021; TechNavio reports that NIPPON MEKTRON, Zhen Ding Tech, TTM Technologies, and Unimicron are key PCBs parts suppliers.
