The 2006–2007 Brazilian aviation crisis was a crisis in Brazil's civil aviation system characterized by massive flight delays and cancellations, air traffic controller strikes and safety concerns about Brazil's airport and air traffic infrastructure. It ostensibly started after the crash of Gol Flight 1907 in September 2006, and extended to January 2008. While the government has announced a series of measures aimed at mitigating its effects, no clear solution has been found.〔(Al Jazeera English - News - No Survivors In Brazil Air Crash )〕〔(Reuters AlertNet - FACTBOX-Brazil's deepening aviation crisis )〕 In Brazil the crisis has been dubbed "''Apagão Aéreo''" ("Aerial Blackout"), an allusion to an energy crisis which Brazil experienced between 2001 and 2002. ==Brazil's air traffic control system== Brazil's air traffic control system is run by the Brazilian Air Force (FAB). While some approach controls and control towers may have civilian controllers, the vast majority are military non-commissioned officers supervised by commissioned officers (with the totality of ARTCCs being staffed by the military, under a department called Department of Airspace Control (Departamento de Controle de Espaço Aéreo). The air traffic control centers are known by the acronym CINDACTA, or "Centro Integrado de Defesa Aérea e Controle de Tráfego Aéreo (Integrated Air Traffic Control and Air Defense Center). Four CINDACTAs are in operation, located in four different cities and each responsible for different regions of Brazil's airspace. The use of military air traffic controllers for civilian traffic is not unusual, but has been deprecated in most developed countries. In the US, the Federal Aviation Administration (FAA) operates a wholly parallel system with that of the US Air Force and NORAD. This is also the case of Eurocontrol and each of its member nations' air defense systems. Brazil's use of an integrated command poses some unique challenges to the government. As members of the military, controllers are not allowed to form unions (such as the case of NATCA in the US) or to strike. While the air traffic control system saw significant improvement with the implementation of the Amazon Surveillance System (SIVAM) in the northern portion of the country, there were many warning signs that the system as a whole was heading towards an untenable situation. In 2003 the Brazilian Air Force warned of the need for upgraded equipment and additional funding. For three years, budget requests submitted by DECEA, the Air Force department in charge of air traffic control, were denied.〔 (FAB warns of crisis since 2004. ) O Estado de S. Paulo〕 The government's ''Tribunal de Contas da União'' (Union Accounting Tribunal), an agency similar to the US Government Accountability Office, issued a report after the crisis which echoed the FAB's concerns, stating that a lack of planning and underfunding of the air traffic control system by the federal government was to blame for the crisis.〔 (Budget cut and lack of planning caused air crisis, says TCU report ) Agência Brasil〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2006–07 Brazilian aviation crisis」の詳細全文を読む スポンサード リンク
