(a) Beijing Daxing International Airport (PKX), China's new USD11 billion mega airport in Beijing was opened in September 2019 (Source: BBC News, 2019). The new airport is located around 46 km from Tiananmen Square. Noise pollution from aircraft is a major concern especially for the dense population living in the vicinity. Authorities have been working with the aviation community to address these concerns during the planning stages and even now when the airport is in operation. With reference to PKX, propose three (3) strategies that you think can be applied for noise reduction or abatement at PKX. Give reasons why you chose these strategies. b) Another major concern for aircraft operations is CO2 emissions. However, there are arguments that suggest contribution by air cargo movement to global emissions has been inflated. Defend this argument in the context of PKX.
