Safe Operations of Shared Airspace Act of 2025
This bill addresses aviation safety, such as through increasing requirements for aircraft tracking, communication, and coordination with the military. The bill also addresses Federal Aviation Administration (FAA) workforce issues.
For example, the bill revises and increases requirements for using Automatic Dependent Surveillance-Broadcast (ADS-B) equipment, which transmits information (e.g., location and weather information) between aircraft and air traffic control.
Under the bill, aircraft must generally operate with ADS-B In (receiving) equipment. The FAA must issue performance requirements for the equipment to provide safety-enhancing capabilities (e.g., facilitating aircraft collision avoidance) for flight crews.
Further, current FAA regulations allow aircraft performing a sensitive government mission to be excepted from requirements for using ADS-B Out (broadcasting) equipment. This bill limits which flights may be considered sensitive government missions (e.g., not training flights).
The FAA must also (1) establish an office to coordinate airspace usage of military aircraft, (2) review the safety of certain flight operations and routes around airports, and (3) enter into memoranda of understanding with military agencies for safety information sharing.
The FAA must conduct a Transport Airplane Risk Assessment Methodology analysis for any transport airplane accidents in the United States that result in a fatality.
The bill also addresses FAA workforce issues, such as by
• excluding the FAA workforce from a federal hiring freeze, deferred resignation program, voluntary furlough, or reduction in force;
• supporting the recruitment and training of air traffic controllers; and
• requiring strict adherence to federal conflict of interest requirements.

Specifically, the bill provides funding to enable states and tribal colleges and universities, through a federal-state partnership, to eliminate tuition and required fees for (1) all students at community colleges and two-year tribal colleges and universities, and (2) working- and middle-class students at four-year public institutions of higher education and tribal colleges and universities.
The bill provides funding to enable private, nonprofit historically Black colleges and universities and minority-serving institutions to eliminate tuition and required fees for eligible students.
The bill permanently reauthorizes and otherwise revises the Federal Pell Grant program by
• providing funding to increase the maximum award for each eligible student,
• increasing the duration limit for the use of Pell Grants,
• allowing students to use their awards to cover living and nontuition expenses, and
• expanding eligibility to Dreamer students (i.e., students who have been granted Deferred Action for Childhood Arrivals status and who entered the United States before the age of 16) and students with other immigration statuses.
Further, the bill requires the Department of Education to award grants to eligible states and tribal colleges and universities for improving student outcomes.
