Since the upward forces of air pressure from the air passing below the wing becomes greater, the difference between those two forces is translated into lift (Garrison, 2008).
More recently, advanced analytical techniques not available to earlier generations of aviation designers have changed the formal understanding of the mechanics responsible for wing lift. Specifically, it turns out that most wing lift is actually provided by the angle of attack and that to the extent Bernoulli's Law applies to the equation, it may actually inhibit rather than assist lift (Garrison, 2008). Regardless of the underlying mechanism, nothing more than casual observation of soaring birds was necessary to demonstrate the functional efficiency of winged flight first proven experimentally by Lilienthal in 1891.
Whereas previous technological solutions to the problem of overcoming gravity for the purposes of manned flight relied on lighter-than-air gasses or gliding wings, the Wright brothers' aircraft design was the first to employ aerodynamic lift from horizontal wings and powered thrust together. Gliders like Lilienthal's employed aerodynamic lift in their wing surfaces but relied on wind gusts for power. The Wright brothers attached a propeller to their airframe that was designed to push air exactly the way naval ships of the day used propellers in the water. Their historic flight lasted only 59 seconds but flew nearly 1,000 feet at approximately 10 feet in altitude and demonstrated that, at least in principle, fully independent powered flight was possible (SASM, 2007).
The Evolution of Modern Aviation and its Impact on Society:
The unfortunate paradox that nothing promotes more rapid human technological advancement than warfare was true thousands of years before the birth of aviation and remains equally true of virtually all fields of science and technology. However, despite the unfortunate motive for the rapid evolution of aviation from the Wright Flyer to highly complex and powerful 21st century air and spacecraft in one century, the fact remains that modern aircraft have substantially transformed human life on earth in several major ways. Commercial aviation was the original mechanism of "globalization" and completely revolutionized modern business fifty years ago, long before that concept applied to the computer age. Previously, the only means of intercontinental transportation was via oceanic routes measured in days and weeks rather than hours. The strategic advantages in commercial business of rapid air travel in between geographically remote locations was almost as apparent as the strategic and...
Aviation Safety Program Management The average air traveler rarely sees the essence of recognizing the aviation safety regulations in place. People only and often recognize the factors of safety after a horrific accident occurs. Within the daily working schedules in the private and commercial flights, countless lives of innocent passengers depend on the full implementation of the safety regulations. These safety procedures are in place to protect the lives of the
Aviation Safety Aviation Security "As the first flights began again on September 15, some crews refused to fly, not confident of airport security. Those who steeled themselves to work entered a strange new workplace. With no guidance from the airlines or the Federal Aviation Administration (FAA) on how to handle potential future hijackings, flight attendants inventoried galleys for objects they could use as defensive weapons. Shell-shocked passengers sometimes hugged flight attendants as
It may refer matters within its sphere of action to the commission or council. It is responsible for delegating duties to the Council and modifies or revokes the delegated authority. This shows that the Assembly reviews technical, legal, economic, and administrative operations of the organization (Goglia, Halford & Stolzer, 2010). 2. Discuss the ICAO Rulemaking Process including the rule of SARPs, PANS, and SUPPs Three international bodies conduct Rulemaking: the International
Commercial aviation, therefore, warrants the highest attention to risk management, precisely by virtue of the obvious risks to life and limb first, and devastating financial consequences of materialized risks associated with commercial aviation operations. Designing and implementing a comprehensive risk management program entails specific components to identify potential risks, evaluate their likelihood of occurrence, the magnitude of harm associated with them, and the interrelationship of their statistical likelihood and extent
Aviation Management is a complex issue in any environment. In the 21st century environment Aviation Management faces many challenges. These challenges are related to Globalization, Challenges specific to legacy airlines, Air Traffic control shortages and Ethics including the impact of greenhouse gas emmissions. The purpose of this discussion is to examine the Challenges of the 21st century in Aviation Management and the forces of change. Globalization Challenges for Legacy airlines Like any industry,
The mechanic must have adequate knowledge, training, data for assigned task, tools and equipment, be mentally and physically prepared, take safety precautions, have adequate resources, and have researched FAR, Federal Aviation Regulations, to ensure compliance. The task must be performed with a committed attitude, in accordance with appropriate data and acceptable methods, techniques, and practices that are industry acceptable. The mechanic must perform without pressures, stresses, and distractions, re-inspect
