The NTSB found several reasons as to why the crash occurred. As stated earlier in the paper the conditions at the destination airport were forecasted to be poor visibility and possible icing. When dealing with icy conditions it can be hazardous to aircraft. This is due to the fact that ice on a wing spoils the airflow over it. This causes a loss of lift, and more drag, which can cause a stall to occur at higher airspeeds.
Frostbite happens when the skin and tissues freeze and become damaged due to exposure to freezing temperatures. Commonly affected areas include the feet, hands (especially the fingers), nose, cheeks, and ears. Frostbite can be mild or severe. Mild damage may be reversible, but severe frostbite may result in permanent tissue death or loss. CAUSES This condition is caused by exposing skin to freezing temperatures.
Skiers and recreationalists usually initiate slighter, but every so often more lethal avalanches. An avalanche consists of three key portions. The most instable region of a slope is the starting zone, where unstable snow cracks from the adjacent snow cover and starts to slide. Distinctive starting zones are usually on the higher slopes. However, snow can break at any point on the slope under the right
The metaphor of the butterfly is used because a butterfly’s wings, which are fragile, do not cause a considerable amount of air when they flap their wings. However, that little movement may initiate a series of changes that grows so much that they eventually cause a large storm a tremendously amount of miles away. In the novel, “ A Sound of Thunder”, the butterfly effect occurs. The characters travel
According to International Civil Aviation Organisation both domestic and international plane traffic will probably increas, which means number of the people who suffer from Aviophobia may be grown (5). Fear of flying is broad issue and it may concern a one-quarter of a human population (6). Aviophobia sometimes may be associated with other phobias like claustrophobia or acrophobia. "Claustrophobia is a fear of tight spaces while acrophobia is a fear of heights. Being on an aircraft such as an airplane or helicopter provide the perfect setting for these phobias take place."
Someone says, “Are you ok?” I nod yes and they ski away. I look like Frosty the Snowman coming out of a blizzard in a ski parka. I have learned that sometimes you have to risk getting yourself hurt to save other people from harm. However, I also learned that it is really fun to fly through the air on my snowboard. Avoiding those skiers has allowed me to experience something I would have never done otherwise.
Houses with very thin and soft roofs are easily damaged because of blizzards. Houses, in the area where blizzards occur, will be covered with thick snow. Electric and communications lines are disrupted and damaged and this can also result in fire. Roads become fully covered with the water that melts from snow during blizzard and so the roads become very slippery.
This happens because the water tends to be cooler, atmosphere is much dryer. Hurricanes also tend to weaken when they move over land because of a lack of water supply and the decreasing surface circulation due to friction. Another factor that causes hurricanes to weaken is wind shear. “Wind shear can be defined as the difference of wind speed over a short distance in the atmosphere” (Melina, 2010, para. 5).
David Grayson may have missed out to point an additional factor in such a disaster: The fog and the lack of a working centerline. In the audio log of the last minutes of both flights, the air traffic controller mentions to both pilots that the centerline is out of service. Centerline services often have a color coded message which is especially utilized when there’s a foggy atmosphere present. The centerline services that were not available in addition to the layer of fog add more complexity into this incident, only making the whole event a couple of steps away of an extremely disastrous accident. According to SKYbrary, an electronic source of flight safety and aviation management, flights operating on a low visibility operation require lights in their taxiing, takeoff, and landing.
Trees can either be planted or they can be conserved, such as in the building of a ski resort, to reduce the strength of avalanches. In turn, socio-environmental changes can influence the occurrence of damaging avalanches: some studies linking changes in land-use/land cover patterns and the evolution of snow avalanche damage in mid latitude mountains show the importance of the role played by vegetation cover, that is at the root of the increase of damage when the protective forest is deforested, and at the root of the decrease of damage because of the transformation of a traditional land-management system based on overexploitation into a system based on land marginalization and reforestation, something that has happened mainly since the mid-20th century in mountain environments of developed countries Mitigation In many areas, regular avalanche tracks can be identified and precautions can be taken to minimise damage, such as the prevention of development in these areas. To mitigate the effect of avalanches the construction of artificial barriers can be very effective in reducing avalanche
