Biorhythmic Analysis to Prevent Aviation Accidents

Abstract

Abstract. The Word "Biorhythm" is derived from the Greek word "Bios" which means life and "Rhythm" which means flowing with a regular movement. Biorhythm theory uses mostly scientific methods to chart the rhythms or cycles that affect the internal functioning of the body and of human behavior. This is particularly applicable to the physical, emotional and intellectual or mental abilities. Biorhythm theory states that, at the moment of birth three statistical cycles are initiated and these will recur consistently throughout life. This chapter proposes an investigation of the reasons for human error as a contributing factor in flying accidents. Physical factors such as man machine interactions involved in flying mistakes and a taxonomic approach to errors has been proposed in this chapter, in order to avoid accidents. This chapter presents a new methodology based on a probabilistic approach for biorhythmic analysis in an attempt to prevent aviation accidents. The methodology has been developed using a Gaussian distribution technique for evaluation of the aviation system reliability considering the biorhythmic effects on the pilot. Normal distributed data from the US air force were tested and analyzed. These were based on the performance ability of pilots and the peak demand of the performance using a Gaussian distribution approach. Validation of an aircraft accident due to biorhythm is explained in this chapter with consideration of the peak performance demand and differing standard deviations in the performance ability of each pilot. A new curve named the Incident -Duration Curve has been introduced. This is based on a biorhythmic analysis of Indian and US air force data. The area under normal distribution curve of the US air force data represents the successful performance ability zone * Corresponding author. 208 R.K. Saket, S.P. Kaushik, and G. Singh of the Pilot. The accident zone is the area of operation during which the Performance Demand exceeds the Performance Ability of the particular aircraft pilot. Operation within the zone of the normal distribution curve is successful owing to ability and fitness of the particular pilot. Failure probabilities considering Peak Performance Demand and pilot's ability have been evaluated using a Gaussian distribution approach. A Safety Factor Concept is also given in this chapter. This has been done so as to include biorhythmic analysis in the attempt to avoid aviation accidents. A Stepped Incident-Duration Curve has been utilized in order to evaluate the particular pilot's reliability when using the system. The complete aviation system was evaluated by using Simpson's 1/3 rd rule.

The Effect of Physical Biorhythm Cycle on Some Physical Fitness Factors of Adolescent Volleyball Players

“…The vertical jump test was used to measure lower limb's endurance. In order to measure upper limb's endurance, throwing medicine ball test was used (5) performance of test and practical indication were presented along with the instructions for the tests. How to warm up and tests' time were the same for all athletes during two days of testing.…”

“…How to warm up and tests' time were the same for all athletes during two days of testing. The sit-up test was held in a way that the maximal number of touching the knee by elbow should be recorded in 60 seconds when subject's hands had to be on the back of ears (5). The pull-up test was done with palms opposite the subject (5).…”

“…The pull-up test was done with palms opposite the subject (5). In the vertical jump test, the distance between the base point (the highest point subject's hand could reach while standing) and highest point which was obtained by jumping was set as subject's record (5). To perform throwing medicine ball, the subject stood behind a line drawn on the ground with the feet opened as wide as shoulders.…”

“…Projections were done by using a 2-kilogram medicine ball. This test was run 3 times and the best record was registered (5).…”

“…It can be quite effective on reducing incidents and mistakes without any visible reason and on reducing people's sudden performance by identifying the physical, intellectual, and emotional aspects of the individual (4). The word "Biorhythm" is derived from two Greek words of bios meaning life and rhythmus meaning regular or thought-out motion (5). In the Oxford dictionary, biorhythm is defined as any repeated pattern of physical, emotional, and intellectual activities which some believe to affect human's behavior.…”
