One of my students reported that he was having trouble finding my lecture notes from this course, so I am putting them in one place. I will update this for the last few classes.
Some of the aviation discussions are not yet here.
Yesterday I gave a Grand Rounds presentation at Stanford Med School. My title was
Most of my talk was about the adoption of procedures (checklists) by US military aviation, during and after WW II. It has close analogies to the situation of health-care today. Here is my short presentation. A much longer presentation, with more examples but without discussion of medicine, is here.
Initially, I was concerned that my topic might seem too esoteric for Stanford’s medical faculty. However, their Medical Grand Rounds program covers a lot of ground. My topic was only 1.5 standard deviations away from the mean.
For more of my research on flying paradigms and how technologies evolve from crafts to sciences, please see this page.
I have just uploaded Chapter 1 of my book manuscript. It summarizes four revolutionary changes in how people flew. It outlines some themes of the full book, including People and Work and Is Science Inevitable?. And of course it includes a few gripping tales of accidents averted – or not.
Commercial aviation today is very safe and scientific. But it wasn’t always. Please send comments, anything from typos to critiques.
Over August I will put up some photographs and key tables from the full book.
The Lindbergh Foundation’s Air Shepherd initiative uses drones to catch poachers in South Africa.
My comment: Flying at night, up to 40km away, is technically difficult. But smart autopilots, using GPS and accelerometers, mean that the operators (pilots) don’t have to do hands-on flying except landing and takeoff. Probably every component in the system except the ground vehicles is hobbyist level, although some of the specialized long-range radio gear might need to be hand built. Nothing from aerospace companies. Battery powered, so essentially noiseless. Also, the aircraft itself is the cheapest part of the system.
The article mentions flights of “up to 4 hours.” That is a very long duration, and would require lots of batteries. 2 hours or even less sounds more realistic. Efficient cruising speed is probably is probably around 40 kph (25 mph). If anyone finds other discussions of this project, please let me know.

Why do we follow digital maps into dodgy places? Something is happening to us. Anyone who has driven a car through an unfamiliar place can attest to how easy it is to let GPS do all the work. We have come to depend on GPS, a technology that, in theory, makes it impossible to get lost. Not only are we still getting lost, we may actually be losing a part of ourselves.

As usual, aviation is way “ahead.” Use of automated navigation reduces pilots’ navigation skills; automated flight reduces hand-flying skills. Commercial aviation is starting to grapple with this, but there is no easy solution.
What’s a good place to put supplemental information, especially photos and tables, for my book? I have a lot of old photographs, and putting them into the book itself gets expensive. Some are in color and some are very large. Here are a few examples.
I could set up my own site, or use my publisher’s, but places like Tumblr know how to run photo sites. The ideal features I want include being able to link to pictures on other sites (due to copyright restrictions), able to create tables of contents, etc. Straight chronology won’t suffice.
include Tumblr, Pinterest, Instagram. I don’t use any of them except to dabble, so I don’t know their strengths. Possibly Twitter or Facebook?
All advice welcome. Email me, or post comments here.
One contributor to the A320 crash off Brazil in 2009 (Air France 447) was that the two pilots were making opposite inputs on their control sticks. The aircraft was in a stall, and therefore it was crucial to push the nose down, to regain airspeed. The instinctive human reaction (of untrained people) is to pull the nose up, since the airplane is falling. To oversimplify a long sequence of events drastically, pilot made the correct move, but the other pilot apparently panicked, and pulled back on his control stick. He continued to do this as they fell from 40,000 feet all the way to the Atlantic Ocean.
A new accident report says that the same thing happened in the crash of an Indonesia AirAsia Airbus A320, flight QZ8501, last year.
