ADS-B Privacy: What the ALERT Act Means for GA Pilots

Starting around 2023, several Florida airports discovered a lucrative revenue stream. They partnered with third-party vendors who monitored ADS-B data and automatically generated landing fee invoices for aircraft that hadn’t been flagged in their systems. The formula was simple: approximately $3 per 1,000 pounds of aircraft weight. Pilots arrived at their home airports one day to find invoices in their mailbox for flights they’d completed weeks or months earlier.

The system was designed for maximum extraction with minimal resistance. Pilots often didn’t know they’d been tracked. Invoices appeared unexpectedly. By the time they received notice, the landing had already occurred. This practice exploded across several Florida municipalities before other states took notice. Meanwhile, privacy advocates and pilot organizations watched in dismay as ADS-B—a system that literally saves lives by improving air traffic awareness—became a tool for automated revenue generation.

The problem extended far beyond surprise landing fee bills. The City of Superior, Colorado used ADS-B tracking data to strengthen a noise pollution lawsuit against Rocky Mountain Metro Airport. Cities and county governments began requesting ADS-B data to investigate alleged violations and build cases against general aviation operators. What had started as a safety mandate had morphed into an enforcement weapon—and pilots weren’t about to let that stand. Pilots suddenly understood that their automated broadcasts—required by federal law—could be used against them in court.

This weaponization of ADS-B data created a chilling effect. Pilots began asking themselves: if they’re required to broadcast their position, shouldn’t they also control who’s using it? Pilots began questioning whether flying was worth the legal and financial exposure. Small airport operators worried about litigation. The general aviation community realized that ADS-B privacy protection for pilots wasn’t a luxury—it was essential to the survival of the industry. The practice violated the spirit of ADS-B but exploited a regulatory gap: there wasn’t an explicit ban on non-federal government use of ADS-B data for non-safety purposes.

On January 29, 2025, American Airlines Flight 5342, a regional jet carrying 64 passengers and crew, departed Ronald Reagan Washington National Airport heading to Wichita. That same afternoon, an Army UH-60 Black Hawk helicopter, with three soldiers aboard, was conducting a routine flight near the Potomac River. The two aircraft collided in what became the deadliest aviation accident in the United States since 2009. Sixty-seven people died.

The NTSB investigation revealed a critical detail: the Black Hawk’s ADS-B transponder wasn’t operational. The passenger jet had ADS-B Out but not ADS-B In—meaning it broadcast its own position but couldn’t receive position reports from other aircraft. The helicopter, meanwhile, wasn’t broadcasting its location to anyone. The pilots on both aircraft never saw each other on their displays. The collision was preventable with modern ADS-B equipment. This tragedy became the catalyst that reignited serious momentum for ADS-B In mandates.

The NTSB issued a stark recommendation: all aircraft need ADS-B In capability to see other traffic and respond appropriately. This recommendation drove the development of the ALERT Act. However, the House Transportation Committee recognized something crucial: mandating expensive equipment installations would meet fierce resistance unless they addressed the privacy concerns that had poisoned pilot confidence in ADS-B. The solution was elegant: protect ADS-B as a safety tool by explicitly banning its misuse for revenue collection and enforcement, while incentivizing adoption through affordable portable ADS-B In options.

The amended ALERT Act achieved something rare in Congress: unanimous committee support. The House Transportation Committee voted 62-0 on March 26, 2026. The House Armed Services Committee, which shares jurisdiction on defense-related aviation matters, had already voted 53-0 in support. This level of bipartisan consensus signals serious momentum heading into a full House floor vote and Senate consideration. The bill includes the PAPA (Pilot and Aircraft Privacy Act) provisions that directly address ADS-B privacy protection for pilots.

The central provision of the ALERT Act explicitly prohibits airports—public airports in particular—from using ADS-B data to collect revenue in the form of landing fees, facility charges, or similar assessments. Currently, only the FAA has clear restrictions on using ADS-B data for non-safety purposes. The ALERT Act extends this prohibition to all government entities, closing loopholes that allowed cities and counties to monetize ADS-B tracking data.

The ADS-B landing fee ban doesn’t stop there. It also prevents government use of ADS-B data to initiate enforcement actions or legal investigations unless they involve genuine safety concerns or violations of federal aviation regulations. This prevents scenarios like Superior, Colorado’s abuse of ADS-B data to build noise complaints. It protects pilots from having their federally-mandated broadcasts used as evidence in civil disputes.

The ALERT Act calls for virtually all aircraft to have ADS-B In capability by December 31, 2031. This represents the core of the bill’s safety mission—ensuring that after the DCA accident, no aircraft needs to operate blind to surrounding traffic. However, the bill is smart about implementation. It exempts experimental aircraft and limited-category aircraft, recognizing that requiring expensive avionics on non-commercial operations would be impractical.

Here’s the crucial part for general aviation: the bill explicitly allows portable ADS-B In receivers to count toward compliance. Aircraft under 12,500 pounds can meet the requirement with a ForeFlight Sentry, Stratus unit, or similar portable receiver paired with an iPad or compatible device. This dramatically reduces the cost barrier to compliance and makes ADS-B In adoption feasible for the average general aviation pilot.

For pilots who’ve been uneasy about ADS-B tracking, the ALERT Act represents a fundamental shift in how government can use their data. The bill acknowledges that ADS-B is a safety system, not a surveillance system. It recognizes that pilots need confidence in their equipment for the system to work. When pilots fear that their location data will be used to generate surprise invoices or fuel lawsuits, they become less willing to fly and less confident in their technology. That erodes safety.

The legislation also sends a message to state and local governments considering ADS-B fee schemes: the federal government won’t tolerate it. Several states have already moved to ban the practice themselves. Montana became the first state to prohibit ADS-B fee collection in May 2025. Florida, facing industry pressure and legislative momentum, passed SB 422 in March 2026, effective July 2026. Arizona, Oklahoma, Minnesota, and over a dozen other states are introducing similar legislation.

Additionally, the ALERT Act protects pilots from a threat that extends beyond money: legal harassment. Cities and counties won’t be able to use ADS-B data as a shortcut to building cases against pilots or airport operators. This doesn’t prevent legitimate investigations into actual safety violations—it just prevents the data from being weaponized in disputes where safety was never the real issue.

On February 12, 2026, NTSB Chair Jennifer Homendy testified before the Senate Commerce Committee on ADS-B mandates and privacy protection. Her testimony was blunt: “ADS-B is a safety tool and it should be used for safety, not as a revenue generator to charge general aviation pilots ramp fees or landing fees.” She emphasized that the practice of fee collection “should be prohibited” outright. More importantly, she identified the hidden cost of allowing ADS-B misuse: discouragement of adoption.

Homendy’s statement crystallized the problem. Pilots who worry that equipping their aircraft with ADS-B will result in surprise billing are less likely to install the equipment. ADS-B-derived fees actively undermine the very safety mandate they’re supposed to support. Her testimony gave weight to the argument that ADS-B privacy protection for pilots isn’t just about convenience—it’s essential to the effectiveness of the national airspace system.

The Aircraft Owners and Pilots Association has been vocal in supporting ADS-B privacy protection measures. Jim Coon, general aviation advocates’s director of policy, summed up the philosophy perfectly: “ADS-B is a safety tool, not a cash register.” U.S. general aviation advocates have coordinated with international pilot organizations through the International Council of Aircraft Owner and Pilot Associations, which represents approximately 400,000 pilots from 80 countries across six continents. The unified message from pilots worldwide is consistent: stop monetizing our safety equipment.

U.S. and international pilot organizations have also shown willingness to challenge even allied industries when principles are at stake. In early 2026, both organizations sent a letter to SpaceX regarding Starlink price increases affecting aviation connectivity—demonstrating that pilot advocacy organizations prioritize community interests over corporate relationships. This credibility matters when they advocate for ADS-B privacy protection.

The E3 Aviation Association has actively engaged in advocacy around ADS-B privacy and general aviation safety. As part of the broader pilot community, E3 Aviation understands that technology adoption hinges on pilot confidence. When pilots trust that their equipment won’t be turned into a financial liability, they’re more likely to upgrade and equip their aircraft with the latest safety systems. This creates a positive feedback loop: better equipped aircraft, safer skies, stronger general aviation.

The ALERT Act’s allowance for portable ADS-B In receivers is a game-changer for cost-conscious pilots. ForeFlight Sentry Mini offers an entry-level option at an affordable price point. The full ForeFlight Sentry runs $499–$599. For about $100 more, the Sentry Plus adds additional features for $719. Garmin’s Stratus 3 is positioned at $699. For pilots on tighter budgets, the Stratux open-source platform can be assembled for $389–$439, though it requires more technical DIY setup and integration work.

These portable receivers pair with an iPad or compatible tablet running navigation software like ForeFlight, WingX, or others. The beauty is simplicity: you mount the receiver on your panel or window, connect it via WiFi to your device, and suddenly you’ve ADS-B In visibility. You see other traffic, TFR information, and weather. For aircraft under 12,500 pounds, the ALERT Act says this approach satisfies the ADS-B In requirement completely.

For pilots who prefer integrated glass cockpit solutions or who operate heavier aircraft, panel-mounted ADS-B In/Out systems remain the standard. Costs range from approximately $3,695 to over $10,000 depending on your existing avionics, whether you’re upgrading or installing new, and the specific equipment selected. Installation labor is often as expensive as the equipment itself. However, for professional operators, flight schools, and aircraft that will be in service for decades, the integrated approach makes sense.

The ALERT Act doesn’t prohibit these installations—it simply allows the more affordable portable approach to serve as a sufficient alternative for Part 91 general aviation aircraft under 12,500 pounds. This flexibility is what makes the mandate realistic and implementable without creating financial barriers that would stall adoption.

Representative Sam Graves of Missouri authored the ALERT Act. A 26-year veteran of Congress, Graves has been a genuine advocate for general aviation throughout his career. He’s not just a legislator who flies—he’s an active pilot. Graves owns a Piper PA-11, a classic tailwheel aircraft, and he co-owns a T-6 Texan and a BT-13 Valiant with other aviators. His aviation bona fides are real.

On March 27, 2026—one day after the House Transportation Committee passed his bill 62-0—Graves announced his retirement from Congress. The ALERT Act is shaping up to be his defining legislative legacy. For a pilot-legislator, there’s poetry in leaving office having authored a bill that protects aircraft owners, safeguards privacy, and strengthens the national airspace system. The unanimous committee votes suggest the ALERT Act will pass the full House and likely move smoothly through the Senate. Graves is departing at a moment of triumph.

While Congress moved on the ALERT Act, states didn’t wait. Montana became the first state to legislatively ban ADS-B fee collection in May 2025—a watershed moment that signaled to other states that this issue mattered. Florida, facing sustained industry pressure, passed SB 422 in March 2026, with the ban taking effect July 2026. That’s significant because Florida was ground zero for the ADS-B fee scheme problem.

Currently, Arizona, Oklahoma, Minnesota, and over a dozen other states have introduced or are actively discussing ADS-B privacy protection legislation. The movement isn’t top-down from Congress—it’s rising from the aviation community, airports, and state legislators who understand that monetizing safety equipment undermines the system. The federal ALERT Act will harmonize all these efforts and prevent new fee schemes from emerging in states that haven’t yet acted.

This state-level momentum demonstrates something important about the ADS-B privacy protection pilots movement: it has genuine grassroots support. It’s not a fringe issue. It’s a legitimate concern backed by powerful advocacy organizations, state legislators, federal lawmakers, and safety authorities. When NTSB Chair Jennifer Homendy testifies that the practice should be prohibited, when 62 House members vote unanimously, and when state legislators introduce protective measures, you’re witnessing consensus.

First priority: confirm that your ADS-B Out transponder is working and up to date. This is your legally required system, and it’s the foundation of the national airspace safety picture. Have it inspected if you haven’t in the past year. If you’re not compliant, get compliant immediately. The FAA takes ADS-B compliance seriously, and the integrity of the system depends on every aircraft broadcasting accurate information.

If you operate a general aviation aircraft under 12,500 pounds, seriously evaluate a portable ADS-B In receiver. The cost is low relative to the safety benefit and the compliance advantage. Whether you choose ForeFlight Sentry, Stratus, or Stratux, you’ll gain traffic awareness that could prevent an accident. And once the ALERT Act is law, having ADS-B In will satisfy federal mandate requirements.

If you live in a state that hasn’t yet passed ADS-B privacy protection legislation, contact your state representatives and let them know you support a ban on ADS-B fee collection. States like Florida are passing protections, but momentum varies. Your voice matters, especially in states where bills are under active consideration.

Contact your U.S. House representative and express support for the ALERT Act. It has unanimous committee support, but every floor vote counts. Legislators respond to constituent interest, and if they hear from pilots in their districts, they’ll know this issue matters. Keep it brief, personal, and specific: mention the DCA accident, the ADS-B landing fee problem, and your support for privacy protections.

The legislative process moves quickly once momentum builds, and you’ll want to know when the ALERT Act moves to the House floor and when it reaches the Senate. Being informed allows you to provide timely input to your elected officials.

The DCA accident killed 67 people. It was preventable with ADS-B In. The ALERT Act is, fundamentally, a response to that tragedy. However, it’s also a recognition that mandating new technology without protecting privacy creates resistance. Pilots won’t equip aircraft if they fear the equipment will be weaponized against them. Cities and counties won’t respect federal safety mandates if they see them as revenue opportunities.

The ALERT Act solves both problems at once. It mandates ADS-B In to make the airspace safer, following the NTSB’s safety recommendation. But it also protects ADS-B as a safety tool by explicitly prohibiting its misuse for revenue or harassment. This isn’t anti-government—it’s recognition that government entities have misused the system and need clear legal constraints. The unanimous committee votes show that both Democrats and Republicans understand this logic.

Moreover, the bill makes the mandate affordable by allowing portable receivers. This removes the primary barrier to compliance: cost. A pilot can equip an aircraft with ADS-B In for $500–$700 instead of $4,000–$10,000. This changes the economics of the mandate completely and accelerates adoption. Pilots get ADS-B privacy protection, the airspace gets safer, and general aviation remains viable.

For the average pilot, the ALERT Act means something profound: your government finally understands that aviation equipment serves two masters—safety and convenience. When those masters conflict, safety must win. But when they can align—when a safety mandate can be structured to respect privacy and manage costs—everyone benefits.p>

The House Transportation Committee has passed the ALERT Act unanimously. The Armed Services Committee has passed it unanimously. The next step is a full House floor vote, followed by the Senate. Historical precedent suggests that bills with this level of committee support and bipartisan backing move relatively quickly through Congress. Monitor general aviation advocates’s legislative updates and aviation news sources for timing.

When the bill reaches the House floor for a vote, it could happen within weeks or months—Congress moves unpredictably. Your role isn’t to wait passively for passage. Contact your representatives now. Let them know you support the ALERT Act. When floor votes approach, the volume of constituent communication often influences the voting behavior of undecided members, even though this bill appears to have strong support already.

Additionally, if your state hasn’t passed ADS-B privacy protections, the federal ALERT Act will eventually supersede state law. However, state-level wins matter for messaging and for creating momentum. States that pass protections first signal to other states and to Congress that this is a legitimate concern.

The ALERT Act represents a watershed moment for ADS-B privacy protection pilots. For the first time at the federal level, Congress is explicitly recognizing that safety equipment can be misused and that pilots deserve protection from that misuse. The bill acknowledges the DCA tragedy that drove it—67 people killed because ADS-B In wasn’t mandated. It responds with a mandate. But it also responds to pilots’ legitimate concerns about privacy and cost.

Your ADS-B data is no longer a cash register. It’s a safety tool again—legally designated and protected. The surprise invoices from Florida, the lawsuits fueled by tracking data, the general erosion of pilot confidence in the technology: the ALERT Act stops all of it. Moreover, the bill makes ADS-B In adoption feasible by allowing portable receivers to satisfy compliance, dropping the cost barrier from thousands to hundreds of dollars.

This is what ADS-B privacy protection for pilots actually looks like in practice. It’s not opposition to technology or safety. It’s recognition that technology adopted without trust fails, while technology that pilots trust transforms the airspace. The ALERT Act builds that trust.

Stay informed. Equip your aircraft responsibly. Support the legislation as it moves through Congress. The airspace after this bill passes will be measurably safer and more respectful of pilot privacy. That’s a victory worth celebrating.
