Fatigue, Body Rhythms, Sleep and Fitness how it deals in aviation


The twentieth century was a faithful witness of the evolution of the machines and how these have been "Guardian" of the planet, but we must not lose sight of the designer and creator of those almost incredible inventions, as described by the Cap. David Beaty in his book "The Naked Pilot," is nothing but "a bag very thin waterproof leather, charcoal-filled, calcium and phosphorus combined with oxygen and nitrogen, a few grams of sulfur and chlorine, iron lines, iodine, cobalt and molybdenum, added to fat and forty liters of water: man." However, if we try to be fair, the previous result description while chemical approach is correct, it shows the wonderful and sophisticated machine that is the human being in terms anatomy and physiology, and much less complex than it is in terms psychological. Thus, the following research paper is conducted to analyse how fatigue, body rhythms, sleep and fitness are dealt in aviation.



The study of fatigue and stress involves the difficulty of establishing clear definitions and universally accepted on these items. With respect to stress, some authors suggest that any level is deleterious and others, that a moderate level of stress is necessary for optimum performance. A level not enough stress can lead to boredom and low productivity and excessive stress, a physical or emotional commitment.

Fatigue is considered in different ways by different authors. Traditional considerations regarding aviation medicine have been made in relation to fatigue acute operational impact decreased psychomotor function, decreased performance / individual efficiency and commitment attention. Such fatigue is frequently observed after one or more flights difficult in one day, or even after strong intellectual activity, such as complex an exam.

Acute fatigue should be differentiated from chronic fatigue, being the last one in which the pilot has not been recovered from the first mission to take the second, and then the next, etc.., with cumulative fatigue progressive. In this type of fatigue, the flyer bearing capacity is decreased after each flight consecutive, acute fatigue may be overcome, at least partially, by stimulation personal effort, for example in an emergency in flight or during combat. This type of treatment is fatigue relatively simple, with one or more days of rest and proper nutrition.

The interest in deepening knowledge of the various elements that influence the human factor aviation is necessary to review general concepts fatigue and stress and its impact on specific aerospace medicine, in order to know and adequately treat these risk factors before they have a negative effect on flight operations, pilot and other members of the groups related to aircraft ...
