This bill requires NASA to study how changing atmospheric conditions affect aviation standards and aircraft performance. Working with the Federal Aviation Administration, National Oceanic and Atmospheric Administration, and industry experts, NASA must assess current and historical atmospheric conditions, predict future trends, and analyze how these changes impact the operations and costs of commercial aircraft at major U.S. airports. The study will also examine whether airports need infrastructure upgrades and recommend design modifications for future aircraft to account for atmospheric variations. Additionally, it will review whether federal government aircraft design requirements need updating based on these findings. NASA must submit its findings to Congress within 18 months of the bill's enactment, with no specific funding amount specified in the legislation.
