Everyone’s heard of the “black box”. Officially known as the Flight Data Recorder (FDR), it’s a mandatory piece of equipment on commercial aircraft. The FDR is instrumental in investigating incidents or crashes, and is specifically designed to survive should the aircraft be destroyed. The search for the so-called “black box” often dominates the news cycle after the loss of a commercial aircraft; as finding it will almost certainly be necessary to determine the true cause of the accident. What you probably haven’t heard of is a Quick Access Recorder (QAR).
While it’s the best known, the FDR is not the only type of recording device used in aviation. The QAR could be thought of as the non-emergency alternative to the FDR. While retrieving data from the FDR usually means the worst has happened, the QAR is specifically designed to facilitate easy and regular access to flight data for research and maintenance purposes. Its data is stored on removable media and since the QAR is not expected to survive the loss of the aircraft it isn’t physically hardened. In fact, modern aircraft often use consumer-grade technology such as Compact Flash cards and USB flash drives as storage media in their QAR.
Through the wonders of eBay, I recently acquired a vintage Penny & Giles D50761 Quick Access Recorder. This was pulled out of an aircraft which had been in service with the now defunct airline, Air Toulouse International. Let’s crack open this relatively obscure piece of equipment and see just what goes into the hardware that airlines trust to help ensure their multi-million dollar aircraft are operating in peak condition.
It’s Still Built Like a Tank
The Quick Access Recorder might not be intended to survive in a crash, but it’s still an expensive piece of hardware installed in an even more expensive aircraft, so this thing is still built like a tank. The case itself is best described as a metal shoe box: the bottom and sides have all been expertly welded together to create one continuous piece of metal, and only the top “lid” can be removed by loosening twelve captive screws around its perimeter.
The front of the QAR has a handle and some locking tabs, so it looks like this device was meant to slide into an electronics rack of some type rather than being permanently mounted. There’s a power LED down at the bottom, but everything else is covered by a locking door during normal operation. Under the door is a slot for the tape the device stores its data on, status LEDs marked BUSY and READY, and an Eject button. Interestingly the Eject button is electronic rather than being connected to a physical mechanism, but it did help explain why the QAR arrived to me with a tape stuck inside of the drive.
I was able to remove the tape from the QAR without too much trouble, but unfortunately it doesn’t provide us with a whole lot of information to go on. The label says it was put …read more
A new study from Nature Plants has identified the one climate-related issue that can unite people from myriad political backgrounds — beer. From a report: Led by Wei Xie, an agricultural scientist at Peking University, the paper finds that regions that grow barley, the primary crop used to brew beer, are projected to experience severe droughts and heat waves due to anthropogenic climate change. According to five climate models that used different projected temperature increases for the coming century, extreme weather events could reduce barley yields by 3 to 17 percent. Barley harvests are mostly sold as livestock fodder, so beer availability could be further hindered by the likely prioritization of grain yields to feed cattle and other farm animals, rather than for brewing beer. The net result will be a decline in affordable access to beer, which is the most commonly imbibed alcoholic beverage in the world. Within a few decades, this luxury may be out of reach for hundreds of millions of people, including those in affluent nations where breweries are a major industry. Price spikes are estimated to range from $4 to over $20 for a standard six-pack in nations like the US, Ireland, Denmark, and Poland.

An anonymous reader shares a report: Artificial intelligence is now being used in an ever-expanding array of products: cars that drive themselves; robots that identify and eradicate weeds; computers able to distinguish dangerous skin cancers from benign moles; and smart locks, thermostats, speakers and digital assistants that are bringing the technology into homes. At Georgia Tech, students interact with digital teaching assistants made possible by AI for an online course in machine learning. The expanding applications for AI have also created a shortage of qualified workers in the field. Although schools across the country are adding classes, increasing enrollment and developing new programs to accommodate student demand, there are too few potential employees with training or experience in AI. That has big consequences. Too few AI-trained job-seekers has slowed hiring and impeded growth at some companies, recruiters and would-be employers told Reuters. It may also be delaying broader adoption of a technology that some economists say could spur U.S. economic growth by boosting productivity, currently growing at only about half its pre-crisis pace. […] U.S. government data does not track job openings or hires in artificial intelligence specifically, but online job postings tracked by jobsites including Indeed, Ziprecruiter and Glassdoor show job openings for AI-related positions are surging. AI job postings as a percentage of overall job postings at Indeed nearly doubled in the past two years, according to data provided by the company. Searches on Indeed for AI jobs, meanwhile increased just 15 percent.
