Our market right now is general aviation and business jets. I believe our biggest customer is the Cessna Citation Longitude (max takeoff ~40,000lbs). I noticed the NTSB abstract had some recommendations for inclusion and certification of a

I get excited seeing stories about aviation on HN because it's something I work on every day. I've written a few comments above but I'm developer on the system you described (and more) being used in aircraft today. With a GPS

Good question. We've run into similar issues while developing a related feature that helps pilots perform a stable approach. Sometimes pilots were performing a circling approach to a different runway, and a naive approach to determinin

We do get some nuisance alerts from time to time, and part of my job is to investigate them and determine the cause. I did investigate one recently, however, where the cause was a runway that was "one-way". Most runways have two e

We actually don't use the localizer to check for an incorrect runway or taxiway landing because the pilot can choose to do so and we don't want to issue nuisance alerts. Runways don't move often and we've found that a GP

I've been anticipating the release of this report this since I heard about the incident. I work on an avionics product that's designed to prevent this exact scenario. We use the aircraft's position along with a database of ru

I think there's some truth to your GNS 530 theory... Pilots are not typically that interested in stylish/modern UIs, and they're not thrilled when a familiar UI changes. There are so many features now that it's a challen

Me too. This is something that already exists today [0]. It can detect when the aircraft is not lined up with a runway and issues a "Taxiway Landing" aural and visual alert. [0] https://buy.garmin.com/en-US/US

Correct, there was probably a significant amount of simulator testing. Keep in mind that these kinds of simulators use real hardware and the avionics are being given inputs just like in the aircraft (i.e. the GPS antenna is simulated, but G

Not true, 95% of commercial aircraft have a TAWS system [0] that can show relative terrain on their navigation displays and provides FLTA alerts (forward looking terrain avoidance) by using an onboard terrain database. This is an FAA requir

I'm interested in learning more about how the various libc's are implemented. Can someone suggest one (or other C code) that I can download and look through? I am trying to find high quality open source C to learn from. Thanks

I've seen a few comments on HN and the blog about this question -- I think it's important to note that the article mentions this question was a set of pictures: >>One test had many rows of small pictures, and I had to choose the odd
