Environmental Regulations in the USA - Essay Example Conservation and management of resource laws deals with a single resource like natural resources for example forests, animal species and intangible resources like archeological sites. Environmental regulations are influenced by principles of environmentalism including sustainability, conservation, ecology, stewardship, and responsibility. Environmental regulations are mainly aimed at protecting and preserving human health and natural environment (Pizer 123). Resource conservation and management laws try to balance the benefits of exploitation of economic resources as well as their preservation. The law aims at preventing externalities, in the present and in future, and conservation of public resources from individual exploitation. The expenses and limitations of such laws on commerce and non-money benefits of protecting the environment have generated and is still attracting a lot of controversy. This has led to the inception of the following acts: Environmental Policy and Planning: National Environmental Policy Act (NEPA) of 1969; Environmental Quality Improvement Act (EQIA) of April 3rd, 1970; Federal Facility Compliance Act of 1992 (FFCA). Environmental Policy and Planning: National Environmental Policy Act of 1969 is an environmental law in United States that promotes environmental enhancement. The law led to the formation of the environmental quality presidents’ council. The most significant function of NEPA of 1969 was to set up procedures that had to be a requirement for all agencies of federal government, preparation of environmental assessments and statements of environmental impact. These requirements are applied by all federal agencies in the executive branch og government. However, it does not apply to the congress, president or federal courts. Â

University of Miami - Essay Example As a function of this, UAVs operating in various places throughout the world, namely Iraq and Afghanistan, began to suffer a high attrition rate due to the icing of the wings that invariably occurs at high attitudes. As such, this represented a primary design flaw in that the UAV manufacturers had not foreseen the fact that due to the pilotless nature of the aircraft, it would be nearly impossible for a UAV pilot to notice and infer that icing was taking place; let alone seeks to counteract such an eventuality by employing countermeasures. Moreover, the analysis will look at the use of FEA as a means of solving the complex problems that the engineers were faced. In order to rapidly and cost effectively integrate such a level of changes, the engineers went back to the proverbial drawing board and utilized CAD (Computer Assisted Design) to seek to draw a further level of inference upon the issue at hand. Mainly, these tools were used by the analysts to seek to determine the CFD properties that the wings exhibited. The CFD, or Computational Fluid Dynamics, was a way that the engineers could seek to provide the wings and surface areas of the associated aircraft with the highest level of protection against the accumulation of ice without having the cover the entire aircraft in costly, heavy, and ultimately ineffective de-icing mechanisms. The overall importance of seeking to maximize the level of â€Å"bang for the buck† with relation to where the de-icing systems were ultimately installed centered upon the fact that the sheer nature of the jobs which the UAV’s perform and support require that they remain aloft for extraordinarily long periods of time. As a function of this, it is necessary for these aircraft to be as light, and as fuel efficient as possible. Likewise, seeking to utilize CAD and CFD to determine what aspects of the aircraft lay at the greatest degree of risk with
