The Aviation Funding Stability Act of 2025 aims to ensure that the Federal Aviation Administration (FAA) can continue its operations even during a government shutdown. The main goal is to provide a reliable source of funding from the Airport and Airway Trust Fund, which is crucial for maintaining aviation safety and services. Key provisions of this act allow the FAA to access funds from the Airport and Airway Trust Fund if there is a lapse in appropriations, meaning if the government does not pass a budget on time.
