The 3D Experience: Avionics Software Design, Development and Data Coupling

Not every profession has to use three dimensions. Artists, musicians, writers, and tax attorneys alike usually only need to consider two planes of existence in their professional lives. But aerospace engineers and avionics professionals have a unique relationship with all dimensions. Dealing with all planes all the time (pun absolutely intended) is no small feat, and it’s especially important (and ironic) when working within a platform that only uses two dimensions: Avionics Software Design. So, for this article, we’re going to cover a different, non-spatial “3D;” let’s talk about the design, development and use of data coupling for Avionics software. Continue Reading > > >

The Aerospace Coverage Sack: Structural Coverage Analysis in DO-178C Verification

Sunday marks the end of the 2022 NFL season with the stupendous spectacle that is the Super Bowl. So, it should be no surprise that (American) football jargon was in the ConsuNova air this week. The “Power sweep,” “nickel package,” and “icing the kicker” are just a few of the phrases expressed on “any given Sunday,” though one stands out as an avionics and aerospace crossover: “the coverage sack.” For good measure, put simply, a “coverage sack” occurs when the defending team tackles the quarterback because no receiver was “open” to receive a pass. Though the analogy is a stretch, Continue Reading > > >

Autopilot Engaged? Automated vs. Manual DO-178C Verification

There’s a lot of talk about AI, blockchain and automation these days. Between robots taking over everything and predictions of everyone working in the enigmatic digital world that is “the metaverse,” it’s hard not to consider how advanced technologies like these can be applied to the aerospace industry. When it comes to software development and its guidelines, namely DO-178C, we know of at least one way: automated verification. A number of verification activities are required by DO-178C. Some of these activities involve verification of the developed software, while some involve verification that your DO-178C verification process was correctly followed. Many Continue Reading > > >
