Aircraft Crash Survival Analysis and Design Essay

Aircraft Crash Survival Analysis and Design - Essay Example While the paper dwells on the basics operation and construction of ejection seat, it also brings out new developments in the field. Emergency escape from a malfunctioning aircraft is of utmost importance for any Air Force. The cost of training a fighter pilot is prohibitive and time taken for him to become operational is significant. Therefore all efforts have to be made to save a fighter pilot from the malfunctioning aircraft. In the older era, the aircraft envelope was fairly limited. The speeds of the pre World War I fighters were low enough to permit manual bail out, where in, the pilot jumps out of the aircraft with parachutes on. However, the modern day fighter class of aircraft operates at speeds beyond Mach .2.0 and at altitudes from Ultra Low Levels (30m) to beyond 60,000’. The kind of maneuvers performed by the fighter pilots during operations leave little margin of error. Flying at such envelope, it would be impossible for a fighter pilot to bail out from the aircraft manually. Therefore ejection seats are a must for a safe escape from the malfunctioning aircraft. The ejection seats not only pr ovide a means of escape from the malfunctioning aircraft, but also house the Pilot Survival Pack which contains adequate reserve equipment for the pilot to survive for about 48 hours till rescue arrives. The type of survival pack would depend on the type of terrain over which the pilot is expected to operate namely jungle, snow or water. The first bungee assisted escape from an aircraft took place as early as 1910. Earliest example of ejection seat was a seat using compressed air, patented in 1916 by Everard Calthrop. The current design for ejection seat is attributable to Romanian inventor Anastase Dragomir. Dragomir patented his "catapult-able cockpit" at the French Patent Office (patent no. 678566, of April 2, 1930, Nouveau systà ¨me de montage des parachutes dans les appareils de locomotion aà ©rienne). This design was successfully tested on

Essay on Punishment and the Prodigal Son of The Holy Bible

Punishment and the Prodigal Son    In American Society today, there exists a feeling that those who have transgressed, whether against individuals, family members, or society at large, need to be held responsible for their actions. The more severe the transgression, the more severe the punishment. It is not unheard of in these times, for example, that a parent may let his or her child spend a few nights in jail in order to "teach them a lesson". Even if the child seems to understand the severity of his or her actions, and shows regret for these actions, punishment may still be dealt out in the name of "tough love". In The Parable of the Prodigal Son, Jesus seems to suggest that punishment is unnecessary for those who have redeemed themselves.    The two sons in this story represent several easily recognizable character traits still found in people to this day. The older son is a hard working, responsible, obedient man who expects that someday his discipline and sacrifice will pay off. Although not specifically mentioned in this short parable, it can be assumed that his share of his father's... ...f they show regret. A problem with the father's solution to his wayward son, however, is that it may encourage this very type of behavior to continue in others who decide there is no consequence to their actions, as long as they repent, or pretend to repent, in the end. In this parable, it is easy to see that the prodigal son has been redeemed, and deserves compassion from his father. However, judging the salvation of an actual person is never as simple.

A Quality Management Case Study Defects Essay

Quality Control is developing evaluation schemes to ensure products are designed and produced to meet or exceed customer requirements. Any unit of production not meeting the standard is immediately eliminated. Researchers apply the Pareto principle implying that very few quality defects account for the larger quality losses. Pareto diagrams allow us to separate vital few factors that cause majority defects from the less contributing factors. Resources are then used to correct these factors and optimum quality standard is achieved. This study examines for defects found during final inspection of printed circuit before they are integrated into the next higher assembly. Manufacturing process followed standards such as MIL-Q. It’s a standard written by the government used even by commercial enterprises. Whenever we have a defect cited, a discrepancy report (DR) is generated. The DR record keeps track of when what defect was detected by whom and where. It also stores information about what action was taken to restore quality unit. Defects are classified as types (In this study, there are 31). These broad categories are further sub categorized. In nutshell, this effort of planning quality is the essence is Quality Assurance. Using the online DR system, Managers analyze defects. First, Managers find out the correlation between inspections and defects. Pearson’s coefficient is a valuable indicator of that. Secondly, Managers analyze the ratio of defects to no. of inspections per week. To crack the whip on detailed data of actual defects, Pareto analysis (Quality Control measure) is performed. Significantly, it shows percentage of defects caused by the key defect types. Working groups are formed to drill down on the last few vital factors to suggest corrective actions and completely eliminate defects. New drawings, procedures are designed and applied to achieve highest quality. During the highest problem period in this study, no. of inspections went down drastically. One reason could be that the work completed was less (because of more defects) and so the number of inspections went down. But the repaired boards needed to be inspected. Inexperienced operators could be the other reason. This leaves a lot of work yet to be done in this field. This study however does benefit quality management efforts. Although, this case is specific to the airline industry, the approaches described here can be usefully applied to any project. Maintaining quality is a very crucial task and any project management must seriously focus on it. Harvard Business Review

Identifying Independent and Dependent Clauses

An independent clause (also known as a main clause) is a word group that has both a subject and a verb and can stand alone as a sentence. A dependent clause (also known as a subordinate clause) is a word group that has both a subject and a verb but cant stand alone as a sentence. A sentence may consist of a single independent clause, multiple independent clauses linked by a conjunction, or a combination of independent and dependent clauses. The key to distinguishing a dependent clause is this: a dependent clause adds information to the independent clause. Perhaps it gives context about time, place, or identity, perhaps it answers why? the action in the independent/main clause is happening, perhaps it clarifies something from the main clause. Whatever the case may be, the information contained in that clause is in support of the the main clause. This exercise will help you recognize the difference between an independent clause and a dependent clause. Instructions: For each item below, write independent if the group of words is an independent clause or dependent if the group of words is a dependent clause. The details in this exercise have been loosely adapted from the essay Bathing in a Borrowed Suit, by Homer Croy. ____________________I went to the beach last Saturday____________________I borrowed an old bathing suit from a friend____________________because I had forgotten to bring my own bathing suit____________________while the waist on my borrowed suit would have been tight on a doll____________________my friends were waiting for me to join them____________________when suddenly they stopped talking and looked away____________________after some rude boys came up and began to make insulting remarks____________________I abandoned my friends and ran into the water____________________my friends invited me to play in the sand with them____________________although I knew that I had to come out of the water eventually____________________a large dog chased me down the beach____________________as soon as I got out of the water Answers independentindependentdependentdependentindependentdependentdependentindependentindependentdependentindependentdependent
