Introduction.
Background of the study
Traveling through the air is one of the most prominent transportation well known in our current time.
Airplanes are made so that our travel will be more efficient and fast when going to other countries. And safety is the
top priority in aviation as it is important to the lives of the passengers and aircrews on board. However Pilot fatigue is
a major issue in modern aviation, owing to the unpredictability of work hours, long duty periods, Cicadian Phase and
insufficient sleep that are all too frequent in both civilian and military aircraft operations. Although the full impact of
fatigue is often underestimated, many of its negative consequences have long been recognized. Persons who are
sleep deprived think and move slower, make more mistakes, and have memory problems than people who are wellrested. These unfavorable consequences can and do result in aircraft mishaps and blunders. “Great pilots are made
not born… A man may possess good eyesight, sensitive hands, and perfect coordination, but the end result is only
fashioned by steady coaching, much practice, and experience.” — Air Vice Marshal J. E. “Johnnie” Johnson, RAF.
Factors that cause human fatigue, like sleep deprivation, circadian rhythm abnormalities, health-related
tiredness and task-induced influences, may have adverse effects on human performance. Solutions to these issues
are not simple, but they may be developed with the help of air crew members, managers, and the pilots themselves.
As we all know the risks in flying the aircraft when your body is in bad condition. It has been noted that fatigue
creates complication in every flight and has become more complex than normal. This attracted the attention of the
researchers and created the concept of knowing where this fatigue originates.

Fatigue Countermeasures in Aviation
Pilot fatigue is a significant problem in modern aviation operations, largely because of the unpredictable work hours,
long duty periods, circadian disruptions, and insufficient sleep that are commonplace in both civilian and military flight
operations. The full impact of fatigue is often underappreciated, but many of its deleterious effects have long been known.
Compared to people who are well-rested, people who are sleep deprived think and move more slowly, make more mistakes,
and have memory difficulties. These negative effects may and do lead to aviation errors and accidents. In the 1930s, flight
2
time limitations, suggested layover durations, and aircrew sleep recommendations were developed in an attempt to mitigate
aircrew fatigue. Unfortunately, there have been few changes to aircrew scheduling provisions and flight time limitations since
the time they were first introduced, despite evidence that updates are needed. Although the scientific understanding of
fatigue, sleep, shift work, and circadian physiology has advanced significantly over the past several decades, current
regulations and industry practices have in large part failed to adequately incorporate the new knowledge. Thus, the problem
of pilot fatigue has steadily increased along with fatigue-related concerns over air safety. Accident statistics, reports from
pilots themselves, and operational flight studies all show that fatigue is a growing concern within aviation operations. This
position paper reviews the relevant scientific literature, summarizes applicable U.S. civilian and military flight regulations,
evaluates various in-flight and pre-/postflight fatigue countermeasures, and describes emerging technologies for detecting
and countering fatigue. Following the discussion of each major issue, position statements address ways to deal with fatigue in
specific contexts with the goal of using current scientific knowledge to update policy and provide tools and techniques for
improving air safety.
Fatigue in aviation
Pilot fatigue is a significant, but often under-reported problem in both civilian and military aviation operations.
Although estimates vary, official statistics indicate that fatigue is involved in at least 4–8% of aviation mishaps, and surveys of
pilots and aircrew members reveal that fatigue is an important concern throughout today's 24/7 flight operations. Regulatory
efforts aimed at limiting flight hours and ensuring at least minimal periods of crew rest have to some extent mitigated
fatigue-related difficulties in the cockpit, but it is clear that much remains to be done about this insidious threat to air safety.
Scheduling factors, sleep deprivation, circadian disruptions, and extended duty periods continue to challenge the alertness
and performance levels of both short-haul and long-haul pilots and crews. Solutions for these problems are not
straightforward, but they can be developed through the cooperative efforts of scientists, regulators, managers, and the pilots
themselves. Over the past 20 years, scientific understanding of human sleep, fatigue, and circadian rhythms has expanded
considerably. The thorough integration of this new knowledge into modern crew-resource management practices will
facilitate the establishment of optimal crew scheduling routines and the implementation of valid aviation fatigue
countermeasures.
Human Factors in Aviation
At any point in the history of human factors in aviation, one could characterize its current state at that time by the
progress that had been made and by the opportunities that presented themselves for the future. Keeping this in mind, this
chapter aims to provide a brief snapshot of aviation human factors. It first highlights a few brief themes that show the
progress that has been made in aviation research. Following this, it discusses the opportunities that human factors
professionals, pilots, instructors, maintenance personnel, air traffic controllers, and interested parties in general are
presented with currently to drive future generations of aviation. The chapter orients the reader to the causes and effects that
guide the cutting edge of the field now.

Human Error Perspectives in Aviation
As aircraft have become more reliable, humans have played a progressively more important causal role in aviation
accidents, resulting in the proliferation of human error frameworks and accident investigation schemes. To date, however,
few efforts have been made to systematically organize these different approaches based on underlying theoretical
similarities, and formalized methods for evaluating the utility of these multiple approaches have not been clearly defined.
Many safety professionals, therefore, have been at a loss when choosing which error analysis and prevention approach to use
within their organizations. As a result, those tasked with instituting human-centered safety programs often rely primarily on
personal experience and intuition to address their needs. The purpose of this article is to help remedy this situation by
providing safety practitioners with an overview of the prominent human error perspectives in aviation, as well as a set of
objective criteria for evaluating human error frameworks.
History of Aviation
The man has always wanted to be able to fly. The dream or although it has achieved, has not been reached yet fully.
The fuse of the flight today is much higher than in the past, but is not yet complete. Although they have carried out the steps
in the increase of the safety of a ship in flight, there are still many steps to do. For our passengers, but also for our pilots,
these brave people and beautiful, it's time to do something in addition, something more. All those who are to get into a ship
must be confident that they will fly absolutely without any problems, regardless of the weather, time, climate, brightness,
weather conditions, temperature, altitude... In order to achieve a flight higher quality, it is first necessary to know the history
of the flight of the man from its inception up today. The present paper wants to present history human flight, as she was in a
vision as realistic as possible. The paper is addressed to in the first place to all those who contributed or still contribute to the
achievement of this beautiful dream of the man, the flight. According to Aulus Gellius, Archytas philosopher of the old Greek,
a mathematician, astronomers, law and political strategist, was considered that has designed and built around 400 B.C., first
artificial device of the flight is self-propelled, a model in the form of bird propelled by an steam boost (an engine with the
steamer) used as the reactor with steam, about whom they say he flew effectively to about 200 m altitude. This machine,
named by its inventor “The Dove”, could be suspended on a wire to fly securely on a path of feed. The inventor of the
berbers from the ninth century, Abbas Ibn Firnas, is considered by John Harding to be the first attempt of the flight heavier
than air in the history of aviation. In 1010 AD, a British (English) monk, Eilmer of Malmesbury, assumed the piloting of a
primitive sliding boat from the Malmesbury Abbey tower. It is said that Eilmer flew over 200 m (180 m) before landing and
breaking his legs. He later remarked that the only reason he did not fly further was that he forgot to design his flight
instrument and a queue, for which he redesigned his aircraft more technically, but his ancestor took Forbidden any other
experiments on the grounds that they are bad (Satanic inspiration) and lead to serious accidents.
Analyzing aviation safety: Problems, challenges, opportunities
This paper reviews the economic literature relating to aviation safety; analyzes the safety record of commercial
passenger aviation in the United States and abroad; examines aviation security as a growing dimension of aviation safety; and
4
identifies emerging issues in airline safety and challenges for aviation safety research. Commercial airline safety has improved
dramatically since the industry's birth over a century ago. Fatal accident rates for large scheduled jet airlines have fallen to
the level where (along many dimensions) aviation is now the safest mode of commercial transportation. However, safety
performance has not been evenly distributed across all segments of commercial aviation, nor among all countries and regions
of the world. The finding that developing countries have much poorer safety records has been a persistent conclusion
aviation safety research and continues to be the case. Unfortunately, operations data are not available for many of the
airlines that experience fatal accidents, so it is not possible to calculate reliable fatality rates for many segments of the
worldwide aviation industry. Without more complete information, it will likely be difficult to make substantial improvements
in the safety of these operations. Challenges to improving aviation security include: how much to focus on identifying the
terrorists as opposed to identifying the tools they might use; determining how to respond to terrorist threats; and
determining the public versus private roles in providing aviation security. The next generation of safety challenges now
require development and understanding of new forms of data to improve safety in other segments of commercial aviation,
and moving from a reactive, incident-based approach toward a more proactive, predictive and systems-based approach.
Aviation and externalities: the accomplishments and problems
Civil aviation has become a major industry and is one of the fastest growing sectors of the world economy. The
growth of civil aviation has advantages and disadvantages for the society. The advantages include the direct and indirect
generation of new jobs within and around the sector as well as providing a strong stimulus to the globalisation of the
industry, business and long distance tourism. Disadvantages include its negative impacts on the environment. This paper
presents an overview of the impacts of civil aviation on the environment. In particular, it considers some of the important
technological and institutional innovations, that have been implemented in the sector over time in order to simultaneously
increase its efficiency and decrease the negative impacts on the environment. Thus, it illustrates how a `sustainable'
development of the sector is attempted to be achieved through management of the system's noise, air pollution and safety
side effects.
Fatigue in Aviation: Safety Risks, Preventive Strategies and Pharmacological Interventions
Fatigue poses an important safety risk to civil and military aviation. In addition to decreasing performance in-flight
(chronic) fatigue has negative long-term health effects. Possible causes of fatigue include sleep loss, extended time awake,
circadian phase irregularities and work load. Despite regulations limiting flight time and enabling optimal rostering, fatigue
cannot be prevented completely. Especially in military operations, where limits may be extended due to operational
necessities, it is impossible to rely solely on regulations to prevent fatigue. Fatigue management, consisting of preventive
strategies and operational countermeasures, such as pre-flight naps and pharmaceuticals that either promote adequate sleep
(hypnotics or chronobiotics) or enhance performance (stimulants), may be required to mitigate fatigue in challenging
(military) aviation operations. This review describes the pathophysiology, epidemiology and effects of fatigue and its impact
on aviation, as well as several aspects of fatigue management and recommendations for future research in this field.

Summary
The Aviation Industry is currently experiencing problems regarding fatigue and its risk affecting Aviation crews, this
may also influence the future of Aviation unable to recognize their issue concerning aviation difficulties. This discusses the
etiology, epidemiology, and impacts of fatigue, as well as the impact of fatigue on aviation, as well as numerous areas of
fatigue management and suggestions for further studies. But in order to stop this problem, we researchers come up with an
idea that knowing every fatigue will greatly affect both the physical and mental state of every crew member, also this can
help to create and prevent this kind of issue. This will help crew members minimize the fatigue without any extra work
manually assisting it.
Conclusion
Fatigue remains an important safety risk in civil aviation. Possible causes of fatigue include sleep loss, extended time
awake, circadian rhythm disruption, and workload. Despite regulations limiting flight times and suggesting optimal rosters,
not all effects of fatigue are mitigated, where limits may be extended due to operational necessities. Workload greatly affect
all crew members in aviation. Workload situation may lead to reductions in performance, classified as active and passive
fatigue, respectively. High workload situations may exceed the capacity of the fatigued individual due to the high their effort
demanded, whereas low workload situations may lack sufficient stimulation which may unmask underlying sleepiness. These
are the risks that most affect on crew members: decreased mental performance, including impaired alertness and long-term
health effects. Research has shown that fatigue may cause long-term health effects. Although these effects may have a
limited influence on the performance of a fatigued pilot, they may lead to long-term reductions in performance.
Recommendation
Based on the findings and conclusion of the study, here are several recommendations to be considered:
1.The cooperation between resting hours and working hours should be amplify so that the fatigue experience by the
crew reduces.
2. Airline Crew Members should change their attitude and do not always push their body to their limits. They should
observe their body time to time on, and during working hours.
3. Resting one’s body is very important to perform better and execute every task efficiently.
