HR-6222-119
Referred to the Subcommittee on Aviation.
Sponsored by Robert Onder (R-MO)
What it does
The ROTOR Act would require most aircraft to carry ADS-B In equipment, which receives location and traffic information from other aircraft — a technology not currently mandated by law. It would narrow the existing exemption that allows certain government aircraft to skip ADS-B Out (broadcasting) requirements, excluding training flights from eligibility and adding new reporting obligations. The bill would also repeal a 2018 law shielding some military aircraft from ADS-B mandates, require audits by the GAO, DOT Inspector General, and Army Inspector General, and direct the FAA to create a new office coordinating military airspace use and to sign safety information-sharing agreements with military agencies.
Who benefits
General aviation pilots and commercial airline crews who would gain better situational awareness of nearby aircraft, including military traffic. Passengers on commercial and private flights who may benefit from reduced mid-air collision risk. Communities near airports and military flight corridors who could see reduced accident risk. Aviation safety researchers and oversight bodies who would gain more complete flight data. The FAA, which would receive clearer authority and a dedicated coordination office for military airspace. Accident investigators who would have more complete tracking records.
Who is hurt
Military branches — particularly the Army — that would face new compliance costs, audit burdens, and reduced operational flexibility under the narrowed ADS-B Out exemption. Aircraft owners and operators who would bear the cost of purchasing and installing ADS-B In equipment, which is not currently required. Small general aviation operators and hobbyist pilots on tight budgets who may find equipment upgrades financially burdensome. Government agencies conducting sensitive missions that currently rely on the broader exemption, which would be restricted. FAA administrative staff who would absorb workload from the new coordination office and memoranda of understanding requirements.
Supporters argue
Supporters argue that the absence of ADS-B In mandates and the broad military ADS-B Out exemption create dangerous visibility gaps in U.S. airspace. They point to high-profile near-miss incidents and collisions — including the January 2025 midair collision near Reagan National Airport — as evidence that military and civilian aircraft operating without full tracking pose measurable safety risks. They contend that narrowing the exemption, mandating ADS-B In, and requiring coordinated FAA-military oversight directly addresses the systemic failures that allowed such incidents to occur.
Opponents argue
Opponents argue that mandating ADS-B In equipment imposes real costs on thousands of aircraft owners without clear evidence that the receiving function — as opposed to the already-required ADS-B Out broadcasting — would have prevented specific accidents. They contend that restricting the sensitive government mission exemption and repealing military ADS-B protections could compromise legitimate national security operations by making aircraft trackable in ways adversaries could exploit. Critics may also argue that layering new audits and offices onto the FAA adds bureaucratic complexity without addressing the agency's underlying staffing and resource constraints.
Constitutional context
Congress has broad authority to regulate aviation under the Commerce Clause (Art. I, §8, cl. 3), as air travel is quintessentially interstate commerce. The bill delegates new rulemaking and coordination duties to the FAA; under Loper Bright v. Raimondo (2024), courts would independently review whether the FAA's implementing rules stay within the statutory authority Congress grants here, rather than deferring to the agency's own interpretation.
Checks and balances
Congress gains authority by repealing the 2018 military ADS-B shield and narrowing executive branch exemptions; the FAA gains a new coordination office, but is subject to oversight from the GAO, DOT Inspector General, and Army Inspector General, all of which report back to Congress.
Historical precedent
The FAA Reauthorization Act of 2018 established the original ADS-B Out mandate for most civil aircraft and simultaneously created the military exemption this bill would repeal, making it the most direct legislative predecessor.
