Aviation facilitates long-distance travel, quick package delivery, and is essential to military operations. However, aviation plays a big part in daily life that often goes unappreciated. This can be both good and bad. Aviation enables quick medical transportation for operations like cross-state lung transplants, supports search and rescue operations, and creates jobs. However, it is also a significant factor in climate change, noise pollution, and airports can disproportionately affect the health and home values of residents nearby.
What is Aviation?
Aviation deals with the activities related to the flight, operation, and design of aircraft. Most commonly, the aviation industry is thought of as the commercial airline industry that is travel-based and includes brands like American Airlines, United Airlines, and Emirates.
The Pros of Aviation:
Transportation and Connection-
Flying is the main source of transportation for international tourists, with 58% of travelers opting to fly. This connects people to their families, enables faster trips, offers a wider range of locations, and provides remote communities access to necessities like healthcare and education.
Additionally, flight connects businesses to people across the globe, allowing them to ship their goods and reach new customers. The air freight industry is a large with approximately $ 6.8 trillion worth of goods relying on air cargo to reach their destinations. It also creates package delivery services like UPS, Amazon, and FedEx.
Essential Services–
Aviation facilitates emergency operations like disaster relief, search and rescue, and medical operations. In disaster relief, aviation allows for the delivery of supplies, outside personnel, and medical aid. 35,000 tons of food and 4,800 tons of health-related vital relief cargo were delivered using aircraft in 2023. Aircraft can also better aid in search and rescue because they are not obstructed by obstacles like difficult terrain or broken infrastructure. The equipment on search and rescue helicopters, like infrared cameras, saves lives by accelerating the process of locating survivors where time is of the utmost importance. This is why the Civil Air Patrol operates in about 90% of search and rescue missions in the US.
Additionally, it is not always possible to transport the injured to medical care via a traditional ambulance. Air ambulances can reduce response time, access restricted areas, and provide life-saving care. They can also facilitate cross-state transplants where an organ may be available in one state and the receiving patient is in another. This can increase the pool and possibility for a person to receive the transplant that they need.
Social and Cultural-
Air travel connects people faster than any other transportation system. This allows for culture and traditions to spread across the globe, leading to international relations and a better appreciation for other countries. Ideas, books, and knowledge also pass through the aviation industry because every person who travels somewhere else has their unique ideas and important knowledge that they spread.
Job Creation-
The aviation industry creates about 86.5 million jobs internationally. Secure jobs drive international growth because they provide people with a stable source of income that can be invested back into their country’s economy and children’s education. This is especially growing in Africa and Latin America, where the number of jobs in the aviation industry is projected to double in Africa and increase by 20 million in Latin America by 2043. In North America alone, the industry has brought about 1.4 trillion dollars. 49.2 billion dollars were also invested in the building and renovation of airports, which created more construction.
Fashion-
Aviation Fashion is often supplemented by movies like Top Gun, The Aviator, and Catch Me If You Can, and social media. It combines practicality with fashion and has produced some of the most iconic pieces, like the Ray Ban aviator glasses. Some other notable pieces and brands are bomber jackets, pilot hats, and Aviator Nation.
Cons of Aviation:
Climate Change-
Because there has been an increase in flights, emissions from aviation have grown more than any other type of transportation. Airplanes release CO2 when burning fossil fuels, but they also leave vapor trails, soot, water, and gases like Nitrogen Oxides, and Sulfur dioxide. These combined create contrail cirrus or artificial clouds, which can increase greenhouse gases. While climate change is usually connected to CO2 levels, these non-CO2 effects from aircraft have contributed twice as much to global warming as aircraft CO2 emissions.
Uneven medical disparities-
Aircrafts release CO2, NOx, and SOx, which can negatively affect the people living there, as shown through the higher respiratory disease, morbidity, and mortality rates among people who live near airports. The noise pollution from the airplanes not only lowers the value of homes nearby but also has detrimental effects on residents. It can lead to stress, negative results in children’s cognitive development, and increased rates of hypertension, cardiovascular disease, and hyperactivity.
Innovations:
So many advances have been made since the first airplanes. The average flight today already produces 54% less CO2 than a flight in 1990. Innovations continue to be made to decrease CO2 emissions.
SAFs (sustainable aviation fuels)-
A lower-carbon alternative to jet fuel, first commercially used by United Airlines. SAF, or sustainable aviation fuel, has 85% lower GHG emissions. They are produced by converting renewable or waste materials—such as agricultural residues and used cooking oil—into fuel, sometimes using renewable energy in the process. This approach helps reduce both emissions and waste.
Recycling and Aircraft Design-
Reducing fuel burn and greenhouse gas emissions are critical to minimizing the effects of climate change. This is accomplished through more efficient aircraft designs. One way of making the aircraft more efficient is with truss-based wings, as seen in the picture above. These wings produce as much lift as traditional wings, but much less drag, resulting in less fuel consumption. Another way of making the aircraft more efficient is by using recycled materials to build the plane. When made this way, aircraft are lighter, less expensive, stronger, and easier to repair.
Airports are also doing their part in using recycled materials. The Galapagos Ecological Airport’s terminal is made of 80% recycled materials. It also runs entirely off of renewable energy and has its own desalination plants that allow the airport to use local seawater. This airport is the first ecologically friendly airport and has inspired other airports to be environmentally friendly, like the Bohol-Panglao Airport in the Philippines.
Water usage-
Water usage is an aspect often not associated with aviation, but aircraft need to be cleaned for hygiene, safety, and efficiency (since dirt and grime on the plane can make it heavier and increase fuel consumption). The traditional cleaning process can use up to 13,000 tons of water. However, innovations such as dry washing aircraft have lowered that amount by 95%.
Dry washing, which Emirates Airlines introduced in 2016, uses little to no water. It is a liquid cleaning product that is manually applied and wiped off with a microfiber cloth. It also leaves a film on the airplane that allows planes to stay cleaner for longer and for Emirates to save 11 million liters of water a year.
