Aircraft fuel system - Coursework Example The most optimum engine operation can be realized by supervisory engine management since it enables the pilot to select the most appropriate thrust setting quickly and accurately. Irrespective of the changes in atmospheric conditions, the engine thrust can be maintained at a level predetermined and set by the pilot who can change again the thrust settings to his requirement by changing the thrust lever angle, in which case, the engine adjusts to the new thrust setting without overshooting of N2 or temperature. Thrust is not controlled directly by supervisory control unit, which calculates the value of the main control parameter (N1 or EPR) corresponding to the demand thrust to obtain N1 command or EPR command. This function is called ‘power management’ and the calculating unit is called ‘power management control’ (PMC) (Diesinger 89). Supervisory engine management is used in proven hydro-mechanical fuel control to obtain complete control over all engine func tions and is characterized by a mechanical backup which monitors engine control in case of failure of the electronic control. Supervisory engine management systems, thus, perform functions necessary for engine operation and protection enabling reduction of crew work load and maintenance costs and constitute the last designs using hydro-mechanical control systems (Diesinger 89). The FADEC engine management system uses an electronic control system with a digital computer as the only control unit. The FADEC engine management has taken over all steady state and transient control intelligence replacing most of the hydro-mechanical and pneumatic elements of the supervisory engine control system (Maclsaac and Langton 70). The capability of the digital computer to process a large number of parameters is fully utilized by the FADEC system. The FADEC engine management system provides engine system regulation and scheduling for thrust control in addition to

Israel, Iraq and the USA in Middle East Politics Analysis Essay

Israel, Iraq and the USA in Middle East Politics Analysis - Essay Example Religious issues have also been a constant cause of conflict in these regions†.1 These problems of the region do not originate solely from the Middle East countries alone, as external interventions have contributed largely in the past and prevailing affairs in the region. These intervening outsiders do interject because of vested interest in the oil sources. Interventions of countries like the United States of America and Russia among others have led to the unending squabble and unrest in the region. In most cases, the intruders could easily set the Arabs up in arms as regions like in Israel had internal religious disparities between Christians and Arabs/Muslim. Focusing on middle East and the US relation, this paper will not only seek to unravel the relationship between these three countries, but will also deliberate on their contribution to the politics of the middle east. The Middle East has for a long time now suffered from Socio-economic and political problems. The problems in this region blossoms from the citizens of the region, as well as other countries. The interventions have both exacerbated uprisings, and led to loss of millions of lives in wars and unrest. Other than the resources that entice external countries, terrorist groups that thrive in the Middle East have attracted global attention as countries join hands in fighting terrorism. The mere mention of the word terrorist instills fear to any country or individual, as many countries have experienced terrorist attacks in the past. The relationship between Iraq, Israel and USA emanate from either of those connecting factors. Iraq Iraq has been for a long time pivotal in shaping of the Middle East politics. Other than the recently known invasion by the United States of America, Iraq has experienced decades of political and social economic issues. Baker, Shareen and Ismael3 demonstrates clearly and precisely the events of the American invasion in detail. They analytically reveal the causes of the invasion, the economic, social and political factors that are wrapped around the history of Iraq. The most empirical purpose or invasion of Iraq by the US militia emanated from the belief that Iraq was a terrorist country, a factor that led to the invasion in the attempts to wipe out terrorism completely both in Iraq and other targeted nations. All middle east countries that were suspected to condone the development of terrorist groups. This invasion, religious fanaticism and the long time conflicts with the neighbouring countries acted as pivotal determinant factors concerning the country’s political stature and its effects in the region.i Before and after t he cold war, America and the Russian governments sought to control the oil and water sources in the Middle East. These resources became an issue of conflict in the region leading to numerous political upheavals. Since the times of imperialism, America had convinced Muslims to adopt secular methods of governance and legal systems in order for modernization to take place in the Middle East. Reforms to the former Sharia government and legal systems became a fundamental issue when the secular methods failed (Cleveland and Marti). These reforms led to lengthy political squabbles for many years to the present time. Israeli also played a major role in the politics of Iraq as its neighbor and the fact that Israel collaborated with the Americans in the Anti-Arab movements. This relationship connects the three countries in a
