The coronavirus pandemic has significantly impacted most sectors in our society. Most notably affected is the aviation sector, where domestic and international air traffic has ground to a halt. In the U.S., passenger traffic demand decreased by 96% at the height of the pandemic. Across the globe, COVID-19 infections in nearly all countries have similarly reduced international and global traffic demand to unprecedented levels. Due to these impacts and ongoing virus risks, aviation stakeholders supporting Air Navigation Service Providers (ANSP), airport authorities, and flight operators have modified operations to minimize COVID-19 infection risk (and associated disruptions) while still providing needed services.
