Aircraft ownership and flight activity have become remarkably easy to track. Publicly available registration records, commercial flight-tracking websites, and independent ADS-B receiver networks mean that someone holding nothing but a tail number can often determine who owns an aircraft, where it has been, and in some cases where it is going.
For owners who care about privacy, there is no single switch that solves this. There are three separate FAA programs worth considering, and each one closes a different gap. Used alone, any of them leaves an obvious opening. Used together, they meaningfully reduce what the general public can assemble about you and your aircraft.
This guide explains what each program does, what it doesn’t do, and why the right time to address all three is before you close on an aircraft — not after.
Why Your Aircraft Is Easier to Track Than You Think
Aircraft privacy has three distinct exposure points, and most owners only think about one.
The first is FAA-derived flight data, which the agency distributes to commercial flight-tracking vendors. The second is the ADS-B signal your aircraft broadcasts continuously — received not only by the FAA but by a global network of privately operated ground stations that have no relationship with the agency at all. The third has nothing to do with flight tracking: it’s the aircraft registry itself, which has historically made ownership records readily available to anyone who asks.
Blocking one of these does nothing about the other two.
Most owners who believe their aircraft is “blocked” have addressed a single exposure point. The other two are still fully open.
Program 1: LADD — Limiting Aircraft Data Displayed
The FAA’s Limiting Aircraft Data Displayed program lets aircraft owners and operators restrict how FAA-sourced flight information is distributed and displayed. It offers two levels of blocking, and the difference between them matters more than most owners realize.
FAA Source Blocking
This is the highest level of restriction available within the FAA’s data distribution system. The FAA prevents the aircraft’s flight information from being distributed through its data feed to participating vendors at all.
The tradeoff: the owner generally cannot use that same FAA-derived commercial data to privately track the aircraft. You’ve turned the tap off for everyone, including yourself.
Subscriber-Level Blocking
For most private aircraft owners, this is the more practical option.
The FAA continues providing the aircraft’s data to participating flight-tracking vendors, but those vendors are prohibited from publicly displaying the aircraft’s flight information. The owner can still arrange authorized private access through a participating vendor — so flight operations, scheduling, and your own visibility into the aircraft remain intact.
A LADD request requires:
- Registered owner or operator
- N-number
- ICAO/Mode S code
- Aircraft make and model
- Contact information
- Desired blocking level
- Certification that the submitter is the owner, operator, or an authorized representative
Program 2: PIA — Privacy ICAO Aircraft Address
LADD is important, but it does not make an aircraft invisible.
ADS-B equipped aircraft continuously broadcast information that can be received by ground stations — including privately operated receivers completely independent of the FAA’s data distribution system. LADD has no authority over those. An enthusiast with a receiver and an internet connection is outside the system LADD governs.
That’s the gap the FAA’s Privacy ICAO Aircraft Address program addresses.
PIA allows an eligible aircraft to use an alternate, temporary ICAO aircraft address that is not directly associated with the aircraft’s registration number in publicly available FAA data. This makes it substantially more difficult for someone operating or accessing an independent ADS-B receiver network to immediately connect the aircraft’s broadcasts to its N-number and owner.
LADD addresses the distribution and display of FAA flight-tracking data. PIA addresses the ability to associate an ADS-B broadcast with a specific aircraft. They are not alternatives to one another.
Program 3: Withholding Ownership Information from the Registry
There is another piece of the privacy puzzle that has nothing to do with tracking the airplane at all.
The FAA aircraft registry has historically made aircraft ownership information readily available to the public. Beginning in 2025, federal law provided aircraft owners with a process to request that certain personally identifiable aircraft registration information — including an owner’s name and address — be withheld from public dissemination.
This is a separate request from LADD and PIA, and it’s handled through the FAA’s aircraft registration system rather than the flight-data programs.
For an individual who owns an aircraft personally, or for anyone particularly concerned about publicly connecting themselves to a specific tail number, this can be the most important layer of the three. Flight tracking tells someone where an airplane went. The registry tells them whose airplane it is.
Why All Three Matter
Each program closes a different door.
| Program | What it addresses | What it leaves open |
|---|---|---|
| LADD | Public access to FAA-derived flight activity | Independent ADS-B receivers; registry ownership records |
| PIA | Associating direct ADS-B broadcasts with a registration | FAA-vendor data display; registry ownership records |
| Registry withholding | Public identification of the aircraft’s owner | Flight activity from both FAA and independent sources |
Read across that table and the logic becomes obvious. Any single program leaves two columns of exposure. Taken together, LADD, PIA, and ownership-data withholding significantly reduce the amount of aircraft and owner information readily available to the general public.
What These Programs Don’t Do
None of them makes an aircraft anonymous, and any advisor who suggests otherwise is overselling.
- Independent tracking networks and their historical archives
- Records captured before the programs were applied
- Photographs and spotter networks at airports
- Observable activity at your home base
- Corporate filings and other public records
Each of these can still potentially identify an aircraft or its owner. The realistic goal is not invisibility. It’s raising the effort required from trivial to substantial — which, for the overwhelming majority of people who might go looking, is enough.
Address Privacy Before You Close
Privacy is far easier to establish proactively than to reclaim after an aircraft has already been publicly associated with its new owner. Once a tail number and a name have been linked in public data and archived by third parties, no FAA program un-links them retroactively.
For buyers who value privacy — business owners, public figures, executives, family offices, and other high-profile individuals — ownership structure, aircraft registration, LADD, PIA, and public registry information should all be considered as part of the acquisition and closing process, not as an afterthought once the airplane is in the hangar.
Once an aircraft is acquired, the question shouldn’t simply be “Is my airplane blocked?”
The better question is: How easily can someone connect me to this aircraft and follow where it goes?
