Interesting documentary on SBS about the Germanwings tragedy, if you want a deeper insight see my post on the dirty little secret of civilian aviation. By the way, the two person rule only works if both those people are alive.

Ladies and gentlemen you need to leave, like leave your luggage!

This has been another moment of aircraft evacuation Zen.

Why this bit of wreckage is unlikely to affect the outcome of the MH370 search

If this really is a flaperon from MH370 then it’s good news in a way because we could use wind and current data for the Indian ocean to determine where it might have gone into the water. That in turn could be used to update a probability map of where we think that MH370 went down, by adjusting our priors in the Bayesian search strategy. Thereby ensuring that all the information we have is fruitfully integrated into our search strategy.

Well… perhaps it could, if the ATSB were actually applying a Bayesian search strategy, but apparently they’re not. So the ATSB is unlikely to get the most out of this piece of evidence and the only real upside that I see to this is that it should shutdown most of the conspiracy nut jobs who reckoned MH370 had been spirited away to North Korea or some such. 🙂

A little more seriously, PIO is one of those problems that, contrary to what the name might imply, requires one to treat the aircraft and pilot as a single control system.

The enigmatic face of HALThe problem of people

The Hal effect, named after the eponymous anti-hero of Stanley Kubrick and Arthur C. Clarke’s film 2001, is the tendency for designers to implicitly embed their cultural biases into automation. While such biases are undoubtedly a very uncertain guide it might also be worthwhile to look at the 2001 Odyssey mission from Hal’s perspective for a moment. Continue Reading…

Amidst all the online soul searching, and pontificating about how to deal with the problem of suicide by airliner, which is let’s face it still a very, very small risk, what you are unlikely to find is any real consideration of how we have arrived at this pass. There is as it turns out a simple one word answer, and that word is efficiency, the dirty little secret of the aviation industry. Continue Reading…
