In the present day, Aerotropolis has achieved lot in our sustainability development. I am really proud of what we have accomplished today, although further improvement and progress are always needed. First let me talk about the development on the aircraft since it is my choice of career as well as my passion. The models of aircraft nowadays are eco-friendly, one of the biggest challenges aviation industry had faced in the past is the pollution created from CO2 emission. With today’s aircraft models, all the planes are powered by biofuels. With this implementation, CO2 emission was reduced by far the most. Not only the power generating method, the design of the airplanes we have today has also shown a great difference back when I first worked as a pilot. Instead of the long and narrow body with two wings. What we have today is a wide body airplane equipped with a single wing, the plane is designed as such to reduce wind resistance, which results in less biofuel use. Furthermore, the fat body of this type of aircraft allows the airline to carry more passengers than the old models.
The interior design has also changed; the seats are placed in two levels, as the figure has shown. This design not only effectively use up all the space, the passengers can also have a more comfortable seat arrangement where they can rest comfortably. Although what we have today is a huge step considering the development of environmentally-friendly aircraft, a better, more eco-friendly model is still being developed. So far, the aircraft engineers are developing electronic aircraft that is not only powered by batteries but also from solar energy. However, the difficulties they are facing right now is the weight of the engine as well as the electricity storage tank, those problems might cause burden to the engine that results in waste in electricity and short distant flights. With today’s technology and the experience from our past, I have confidence that as long as we have the will, we will have the solution.
In 2016, while people were aware of the constant pollution aviation industry produced, there were no suitable models of aircrafts that could effectively reduce CO2 emission while simultaneously keep the efficiency. Noise pollution was talked about more than emissions. Back then, the fuel powered aircrafts had lay a burden on the technological development on the aircrafts and the CO2 emission reduction plans. While the demand was to have a fully-booked flight to decrease the numbers of flights as well as the loss on profits from the empty seats, this also caused the plane to become heavier and resulted in burning more fuels. There are some alternatives suggested to replace oil to natural gas, as natural gas burned more cleanly than petrol or diesel and also reduce the tax on fuel consumptions. However, this recommendation was turned down due to the weight and size of gas fuel tanks that were counterproductive on the challenge of high passenger rates, which would bring down the passenger capacity. Engineers were still testing different alternatives to overcome the challenges.
A significant technological development in 2030 was that more and more airlines replaced their old model of fuel powered airplanes into biofuel airplanes. As a city that encourages sustainable development, Aerotropolis Airport regulates the airline that only biofueled planes could land in the city to further boost the popularity of this type of aircraft. Our local airline was the pioneer in replacing all aircraft into biofuel aircraft to set as an example to other airlines. The municipality had collected all the waste produced in the city and took the waste into further-production step for the biofuel production. All the biofuel was then allocated to not only the aircraft industry but also for the public transports in the city. The challenge we encountered in this phase was that the supply of biofuel does not reciprocate to the demand of flights, which was a major issue back then. By 2030, many prior developing countries had become developed countries. People from the said countries started to have more stabled financial supports from themselves to travel around the world and join the trend of culture interaction and exchange from people in different countries. As expected, the demand on aviation industry experienced a high raise. To react to this demand, a high passenger capacity aircraft had to be designed and produced. Therefore, the engineers started their innovative development. It was not until the late 2040s, that the experts had fully designed the suitable model that fulfil the demand of the market, which is the type of aircraft we are using now that I mentioned in the beginning.
