Human Error Classification

Human Error Classification 

In my previous post, I wrote about the related term Pilot Error, I want to extend the information that is very interesting in what are the procedures concerning why accidents happen, as I expressed the term

pilot error does not imply that all errors are the fault of the Pilot.

Now review this other information, my point is too helpful to look at accident statistic in General

Aviation in the past and the latest aviation accidents, because the term Pilot Error give you an idea of the human factor problem.

The most common particular causes of the accidents, in order of incidence, also you can see and read almost all of these area a result of disastrous pilot performance and as a good evidence that not sometimes is  a result of aircraft equipment malfunction .

Loss of directional control , poor judgment , airspeed not maintained ,poor preflight planning and poor decision making, clearance not maintained , inadvertent stalls , poor crosswind handling , poor inflight planning and poor decision making .

In Human Factors a simple model of pilot performance is very essential, and also in my personal interpretation as an Aviation Accident Investigator, that I have been worked in several accidents in the research and participation recovering evidences to have clear information why accidents happened and also why and how the pilot crashed. There were a variety of types of errors.

In Human Factors, there are Human Error, the nature of error, in aviation human error is closely related in the appreciations  of the Aviation Community and in the reality why incidents and accidents happening recently but happen , for this reason all pilots we must always be well prepared on the issues for the prevention of accidents .

For example Error Rates, what that mean? Human Factors anticipated and having established that is normal for a human being make errors but, it is important to ask how often this is likely to occur, and also what error rates are considered normal. I remember I was reading on a Human Factors book, a respectable example on average, a person will make an error in dialing a telephone number on a round dial about once in 20 minutes. Also I remember on that lecture, the author said the performance is rather better with push-button selection. Numerous studies of Human Errors rates during the performance of simple repetitive tasks have revealed that errors can normally be expected to occur about once in 100 times.

These are normal human errors rates, because we are humans, and nobody is perfect, the most important is to recognize on time that error to avoid the accident or incident on time.

Of course it is clear that errors can vary widely depending on the task and also other many factors such as a very important topic in Aviation, like a good example Pilot Fatigue etc.

The Source of errors, in the model SHELL the model described the interface between the Liveware and Hardware (L-H) is very often the source of errors.

This is another interesting issue later I want to write on my Safety Blog regarding these concepts , so these concepts were often some source of errors in general aviation .

This is why CRM is very important to understand to minimize the errors inside the cockpits.

Leadership is also required a good interpersonal skill and a good technical ability, including to communicate well, to manage all the resources effectively to avoid pilot errors during our tasks as pilots.

The Classification of Errors: may be in term of source, an error can occur any time anywhere and also in seconds of time, but the most important is to recognize why the pilot induced the error, and can be attributed directly maybe to inadequate performance inside the cockpit.

The classification of some error as Random Error, Systematic Error, Sporadic Error etc.

As Pilots we need to recognize the kind of error classification, and also of course be applied to the performance of the other task, to avoid an accident or incident.

The basic principle to understand all these concepts is to read and do a good research regarding the classification of errors, by setting a good example and be prepared all the time to be a good Safety Pilot.

Always remember, when accidents occur, the crew is evaluated as a team.
