Ethical case study - Essay Example Airport records show that flight controllers had told the pilots to use runway 22, which is nearby runway 26 which they used, something that pilots claim occurs commonly whenever there is reduced visibility. The aim of this report is to identify management, engineering, regulatory, socio-technical and ethical issues that culminated in the accident, and make appropriate recommendations mainly based on engineering ethics considerations. Since it is impossible to determine a single factor that resulted in the crash of Flight 5191, the NTSB should look at all the components of the system that were not functioning at their optimal level, and single them out for improvement, starting with the ones that have the most effect. For instance, any design errors of the airport and management issues among other factors. Engineering Issues. All the airports that these accidents occur have a similar design, showing a lack of concern by engineers or incompetent since the designers have not modified or improved the design despite its predisposition to result in accidents. Runways of different lengths and meant for different plane sizes are built close to each other, making it difficult for pilots to pick the one they have been cleared for takeoff. To make matters worse, there is an unusually short distance to the runway from the airport terminal, such that pilots do not have adequate space to negotiate their planes safely. In addition, these airports are exceedingly complex, and the runway maps provided to pilots are inaccurate; such that a pilot has to use personal judgment when navigating through the runways. In addition to using a single runway for multiple destination flights, the airport managements allow the use of runaways as a taxiway, making a poor situation even worse (Federal Aviation Author ity vii). Management Issues. The management of Blue Green Airport failed in some aspects of its duties, which

Issues in the Field of Engineering - Essay Example The carbon dioxide laser cutting and wielding machines applies the use of energy state transition which occurs between the rotational states and the vibration states of the carbon dioxide molecule to help in the emission of light long infrared. This wave1lengths often occurs at about 10 Â µm. The carbon dioxide lasers helps in the maintenance of continuous and high levels of the power applied, making them suitable in cutting and marking applications. They are often applied in the cutting of steel and super alloys at various power levels ranging from 1 to 5 kW. The lasers are also applied in the laser eye and in the correction of the laser vision. (Krar 51) Some of the specifications for the cutting and the laser wielding machines which includes the transverse speed, power, Y-axis travel, X-axis travel and the Z-axis travel. Usually there are three different types of carbon dioxide lasers: transverse gas flow, axial gas flow and the sealed tube. For the various sealed tube lasers, the power output is 40 to 80 watts (W) per meter of the each of the tube length. The lasers are usually pumped by flash lambs, near IR laser diodes and also the gas discharge lambs. A number of the specialty laser cutting and welding laser cutting machines are applicable in the cutting of pipes tubes, films, adhesives and composite materials. The laser cutting and welding machines helped in the cutting of machines are specifically designed in the cutting of rubber, plastic, stone, marble, metal, foam, granite and the composite material. Some of the laser cutting and welding machines include integral interface and computer interface. Other systems include moto rized heads, robotic arms, guidance modules, pallets, gantry tables, monitoring systems, cabinets, sensors and laser optics. Various laser cutting and welding machine helps in the designing of applications with highest demand on the cutting speed. The fields of application
