Aerospace Industry
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial, and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, maintain, and repair both aircraft and spacecraft. The border between space and the atmosphere has been proposed as above the ground according to the physical explanation that the air density is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. This border has been called the Kármán line. Overview In most industrial countries, the aerospace industry is a co-operation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Ag ...

San Francisco Fog
Fog is a common weather phenomenon in the San Francisco Bay Area and the entire coastline of California extending south to the northwest coast of the Baja California Peninsula. The frequency of fog and low-lying stratus clouds is due to a combination of factors particular to the region that are especially prevalent in the summer. Another type of fog, tule fog, can occur during the winter. There are occasions when both types can coincide in the Bay Area. The prevalence of fog in the San Francisco Bay Area has decreased, and this trend is typically attributed to climate change. Ocean moisture The Pacific Ocean contributes to the frequency of fog by providing atmospheric moisture and temperature. It is also the primary source of nuclei for the condensation of moisture from vapor into cloud droplets. Moisture evaporated from the ocean surface over hundreds, even thousands of miles of the open Pacific is carried to California from various directions. This water vapor contribute ...

Tower
A tower is a tall Nonbuilding structure, structure, taller than it is wide, often by a significant factor. Towers are distinguished from guyed mast, masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation tower, observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek language, Greek τύ ...

Air Safety
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulations and oversight. Aviation security is focused on protecting air travelers, aircraft and infrastructure from intentional harm or disruption, rather than unintentional mishaps. Statistics Evolution Aviation is safer today than it has ever been. Modern commercial aviation boasts an accident rate of approximately 1 fatal accident per 16 million flights, far lower than historic numbers. On December 14, 1903, the Wright Brothers conducted a test flight of their powered airplane from the slope of Big Kill Devil Hill in North Carolina. Upon takeoff, the airplane lifted about 15 feet off the ground, stalled, and crashed into the sand. Only three da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Federal Standard 595
Federal Standard 595, known as SAE AMS-STD-595 – Colors Used in Government Procurement, formerly FED-STD-595, is a United States Federal Standard for colors, issued by the General Services Administration. History FED-STD-595, 595A, and 595B Federal Standard 595 is the color description and communication system developed in 1956 by the United States government. Its origins reach back to World War II when a problem of providing exact color specifications to military equipment subcontractors in different parts of the world became a matter of urgency. Similarly to other color standards of the pre-digital era, such as RAL colour standard or British Standard 4800, Federal Standard 595 is a color collection rather than a color space. The standard is built upon a set of color shades where a unique reference number is assigned to each color. This collection is then printed on sample color chips and provided to interested parties. In contrast, modern color systems such as the Natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
