• Security Vulnerabilities in Commercial-Aircraft SATCOM Kit

    There has been some press in advance of last week’s Black Hat conference speaking of vulnerabilities in commercial-aircraft flight management systems and possible implications for the safety of flight, for example in a Reuters article by Jim Finkle from August 4. The article is technically fairly accurate on the claims made and the manufacturer’s response,…

  • Don Hudson and PBL on the ITU’s proposal for real-time flight data transmission

    The International Telecommunications Union has been conducting its four-yearly meeting. Its president has apparently promised everyone to make possible the real-time transmission of flight data from commercial transport aircraft in flight. This has been supported by the Malaysian delegate. All according to this news report: MH370: ITU Commits to Integrate Flight Data Recorders with Big…

  • Hijacking a Boeing 777 Electronically

    John Downer pointed me to an article in the Sunday Express, which appears to be one of their most-read: World’s first cyber hijack: was missing Malaysia Airlines plane hacked with mobile phone? by James Fielding and Stuart Winter. The answer is no. To see why, read on. The authors interviewed a Dr. Sally Leivesley, who…

  • Pete Seeger

    Pete Seeger died early today. It popped up on my iPad as I was reading the morning news. There is lots to say about Pete, most of it not by me. The New York Times’s obituary by Jon Pareles does justice to the man. His music speaks for itself. Because, as he would probably say,…

  • A Book on the Fukushima Dai-Ichi Accident

    In August 2011, we held the 11th Bieleschweig Workshop on Systems Engineering. The theme was the accident at the Fukushima Daiichi nuclear power plant. We have just published a book on it. An Analytical Table of Contents may be found at the end of this note. I had convened a mailing list in the days…

  • Detention

    When I was in school in the 1960’s, detention was what happened to you if you attempted to imitate farting when the French teacher was writing on the board, and he figured out it was you. You spent forty-five minutes after school in a classroom with, quite deliberately, nothing to do. It turned out to…

  • Saying the Wrong Thing

    The Guardian yesterday wrote an encomium to the UK government’s Chief Scientific Advisor Prof. Sir John Beddington (I hope they don’t mind that I quote in full): Politics may not be the enemy of scientific method, but they are hardly intimate friends. Science inches along by experiment, evidence and testing (and retesting); politics is often…

  • Root Cause Analysis

    The International Electrotechnical Commission, IEC, is currently preparing an international standard to be known as IEC 62740 Root Cause Analysis. I prepared some material for potential inclusion in the standards document but as of writing it appears it will not be used. I think it is quite useful, so I make it hereby available. The…

  • The State of Modus Ponens and of Rational Discussion

    A bit of intellectual biography, prompted by a couple of days’ free time leading me to a paper written 27 years ago by a pal, which I have just read. I say a little of what’s in the paper, to encourage others to read it. And then I comment on a couple of disappointing aspects…

  • Aerial Collision Avoidance

    Just over a decade ago, in July 2002, there was a catastrophic mid-air collision of a Russian passenger aircraft heading westwards and a freighter aircraft of DHL heading northward, near the town of Überlingen on Lake Constance (Bodensee) in Southern Germany near the Swiss border. I wrote a paper on it about a month later,…
