Review: Killing Zone: How and Why Pilots Die by Paul A. Craig (2nd edition)

 I am not a pilot, but I’m interested in aviation and especially in risk and how we measure and apply risk evaluations to normal activities. This book was recommended as the best comprehensive examination of risk in general aviation flying. Flying, in general, has become safer, although as Craig points out, the common trope that the most dangerous part of flying is the drive to the airport, is true only for commercial aviation;  it is definitely not true for general aviation. An analysis of comparative data reveals that general aviation is far more dangerous than driving.

 

Craig exams the problems with training, unintended consequences of otherwise valuable laws and regulations (e.g., the 1500 hr. minimum to be hired with the regionals placed emphasis on quantity rather than quality and meant that pilots would “bore holes in the sky” rather than seek experience with unusual conditions.) Changes in business practices can also have unintended effects. When it became possible to send digital copies of checks rather than the physical checks themselves, hundreds of pilot jobs were eliminated.  Those jobs had provided important experience flying in adverse weather conditions and circumstances that were now much less available as a training experience. Craig points out that military pilots were flying combat missions with less than 400 hours, but were very successful because of the type of scenario training they had received.

 

The revolution of “glass cockpits” that replaced the old mechanical instruments made flying safer, but counter-intuitively, also more dangerous as pilots needed to become information managers more than “stick and rudder” pilots.  There was the danger of thinking you are safer because of all the safety equipment and information overload that impinged on making the right decision. Was a pilot more likely to take off with a lower ceiling knowing he had auto-pilot and instruments that would have navigate through the weather. A very recent accident I learned about * involved a very experienced pilot (17,700 hours), in a very sophisticated airplane (pressurized Centurion) who mixed bad weather with night flying and poor cockpit management (fuel exhaustion) and got himself killed.

 

Craig examines the major types of GA accidents and analyzes them for lessons that can be learned from each. Ultimately, however, it will be the individual pilot’s decision-making skill, knowing when not to fly, and what circumstances to avoid, that will make more of a difference, I suspect. One of the biggest killers is “get-thereitis” and one NTSB investigator remarked that you should only fly if you have time to spare.  Craig adds to that the admonition that in addition to their pilot’s license and logbook, pilots should be required to have an active account with a car rental company.
