Aviation and the U.S. Economy

You may not have flown today, but something you needed or used today did. The latest electronic gadget, flowers for a loved one, life-saving medicine, or even fresh seafood for supper — many of your most important needs and wants were delivered to you thanks to air travel. The importance of aviation in our lives and to our economy is undisputed. Ensuring we have the safest, most sustainable, and most advanced aeronautics technology is the goal of our hard-working aeronautical innovators.

Why Should I Care?

Here are some fast facts about aviation’s contributions to the U.S. economy:
• 8.97 million flights by U.S. carriers worldwide in 2022
• 24 million tons of freight transported by U.S. airlines in 2022
• $77.3 billion positive manufacturing trade balance in 2022
• 2.2 million aerospace/defense jobs; 602,000 in aeronautics/aircraft in 2022

NASA is working on innovative transformations in aviation

Our vision includes faster air travel, new choices for moving people and cargo through the National Airspace System, and all of it happening more safely and sustainably than ever before.

The Aviation Carbon Reduction Challenge

By 2050, an estimated 10 billion passengers will fly a distance of 14 trillion revenue passenger miles each year. With today’s fleet and operational efficiency, this activity would require more than 620 megatonnes (Mt) of fuel and generate close to 2,000 Mt of CO₂. Imagine meeting that demand for air travel while reducing net CO₂ emissions to zero by 2050.

U.S. aviation goal is to achieve net-zero greenhouse gas emissions by 2050.

Safer, sustainable air traffic operations in the sky

Increased operational efficiency brought on by innovative air traffic management solutions reduces fuel burn, carbon emissions, contrail formation, and ozone impact throughout the National Airspace System.

A view from the front office of a Boeing 787-10 Dreamliner during a series of test flights in 2020 in which NASA flew a pair of research projects to gather data on aircraft noise and test an air traffic management digital data communications tool known as Tailored Arrival Manager (TAM). TAM is a system designed to detect a potential problem – perhaps bad weather or traffic congestion ahead – generate an efficient new course for the airplane to follow that resolves the problem as it approaches its destination, and then digitally transmit the resulting course change instruction directly to the cockpit. Results from these tests of TAM will help enable future flight operations to be more fuel efficient while minimizing delays, especially during busy traffic conditions. The collaboration with Boeing was part of the company’s ecoDemonstrator program.

High-Speed Commercial Flight

NASA’s aeronautical innovators are leading a government-industry team to collect data that could make commercial supersonic flight over land possible, dramatically reducing travel time in the United States or anywhere in the world. At the same time, others are considering even faster, hypersonic air travel with vehicles moving more than 5 times the speed of sound.

NASA is addressing the unique barriers to sustainable high-speed flight.

History

Reassessing a 50-Year Supersonic Speed Limit

Fifty years ago, the federal government banned all civilian supersonic flights over land.

The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won’t startle the public below or concern them about potential property damage. Officially put into effect on April 27, 1973, the ban’s introduction was strongly influenced by public opinion surveys in cities where supersonic military jets were flown overhead, and many folks said they didn’t like what they heard or the way their windows rattled because of the sonic booms.

When an airplane flies at or above the speed of sound, air molecules cannot move out of the way of the airplane fast enough, so the pressure waves combine to generate a large shockwave, which people on the ground hear as a sonic boom.

Advanced Air Mobility Missions are Emerging

NASA is working with its partners in industry, government, and academia to build a system that enables the possibility of safely soaring over traffic in air taxis, providing medical and other emergency services by drone, and receiving packages at your doorstep using faster and more sustainable forms of air transportation.

The graphic also shows city areas, with urban operations for on-demand air-taxi, cargo delivery, airport transfers, high-density corridor, fleet operations, medical transfer, air ambulance, cross-metro transfers, package delivery. Also depicted in the scene are inter-city eCTOL, distribution center/warehouses, regional networks, rural operations, cargo delivery and Inter-City eV/STOL. UML-4 is depicted in orange. UML-3 is in yellow. UML-2 in green and UML-1 in blue.

Safe, sustainable, affordable, and accessible aviation for transformational local and intraregional missions is what Advanced Air Mobility is all about. This illustration highlights some of its potential features and services.
