Flight logs are partly public. Whether flight logs are public depends on what you mean by the term: live and historical flight tracks for most civilian aircraft are free to look up online, aircraft ownership is a public FAA database, and detailed government records like radar data and air traffic control audio can be obtained through a Freedom of Information Act request. Pilots’ personal logbooks, aircraft maintenance records, and flights shielded by privacy programs or national security exemptions are not accessible to the general public.
What You Can Look Up Right Now for Free
Commercial tracking websites like FlightAware and FlightRadar24 show live aircraft positions, altitudes, speeds, and routes for most flights in and around the United States. They also archive historical tracks, so you can pull up where a particular aircraft has flown over recent weeks or months. No account or request is required for basic access.
To find out who owns an aircraft, use the FAA’s Civil Aviation Registry. Searching a tail number (the “N-number” on the fuselage) at registry.faa.gov returns the registered owner’s name and address, the make, model, serial number, and current registration status. It’s free and public.
For a specific accident or serious incident, the National Transportation Safety Board publishes full investigation dockets online. These are often the richest source of detailed flight data anywhere, containing cockpit voice recorder transcripts, flight data recorder readouts, radar plots, air traffic control communications, witness statements, and probable-cause reports. The CAROL system at carol.ntsb.gov covers NTSB aviation investigations back to 1962, and the Accident Docket search at data.ntsb.gov holds the supporting documents. No FOIA request is needed.
When You Need to File a FOIA Request
Records that aren’t in any public-facing system require a Freedom of Information Act request. That includes raw radar data for a specific flight, air traffic control voice recordings outside of an accident investigation, filed flight plans, and internal agency correspondence about a particular aircraft or operation.
How to File With the FAA
The FAA accepts electronic FOIA requests through its online portal for air traffic records, airman certification records, aircraft registry records, and enforcement database records.1Federal Aviation Administration. Make a FOIA Request Mail submissions are also accepted. Whatever route you take, be specific: give the tail number, date and time of the flight, departure and arrival airports, and the type of record you want. Vague requests get slow responses or outright rejection.
Timeline and Fees
Federal agencies must respond to a properly submitted FOIA request within 20 working days. If the agency invokes “unusual circumstances,” that deadline can be extended by up to 10 additional working days with written notice.2Office of the Law Revision Counsel. 5 USC 552 In practice, complex requests often run longer than the statutory clock.
The FAA sorts requesters into fee categories. Commercial requesters pay for search time, review time, and duplication. News media and educational or scientific researchers pay only for duplication after the first 100 pages. Everyone else pays for search time after the first two free hours plus duplication after the first 100 pages.3Federal Aviation Administration. Your FOIA Fee Category Stating a maximum dollar amount you’re willing to pay in your initial request helps avoid surprises.
The 45-Day Clock on ATC Audio and Radar
Timing matters here more than anywhere else in this process. The FAA’s default retention period for air traffic control voice recordings and radar data is just 45 days.4FAA. Section 4. Recorders After that, recordings are overwritten as part of normal operations. If you need ATC audio or radar tracking for a specific flight and there’s no accident investigation preserving it, your FOIA request has to reach the FAA before those 45 days run out. Miss the window and the data is gone.
Some events extend retention. When an accident or incident occurs, related voice and data recordings are preserved under investigation procedures, and radar printouts become permanent.5FAA. Data Recording and Retention Hijacking-related recordings are held at least three years. Tarmac delay recordings are held one year.4FAA. Section 4. Recorders
What You Can’t Get
Aircraft Blocked From Public Tracking
Not every aircraft shows up on tracking sites. Under the Limiting Aircraft Data Displayed (LADD) program, private aircraft owners can ask the FAA to filter their registration and flight data from the agency’s public data feeds. Vendors that subscribe to FAA data are contractually required to honor the block, so participating tracking sites don’t display the aircraft. The 2024 FAA Reauthorization Act codified this right under Section 803, directing the FAA to withhold “the registration number and other similar identifiable data” of a private aircraft from “any broad dissemination or display” on request.6Federal Aviation Administration. Limiting Aircraft Data Displayed (LADD) Air traffic controllers still see everything; only public-facing data is affected.
The Privacy ICAO Address (PIA) program goes further. Every ADS-B-equipped aircraft broadcasts a unique ICAO code tied to its registration; a PIA swaps that code for an alternate address that doesn’t map to the owner in public databases. The program is limited to U.S.-registered aircraft with Mode S 1090-MHz ADS-B equipment, and PIA flights must stay in U.S. domestic airspace. One carve-out matters for records requesters: flight information tied to a PIA used “primarily and predominantly for business or commercial purposes” remains available through FOIA.
National Security and Law Enforcement
Two FOIA exemptions routinely block flight records tied to government operations. Exemption 1 covers properly classified information kept secret “in the interest of national defense or foreign policy.”2Office of the Law Revision Counsel. 5 USC 552 Military flights, intelligence operations, and sensitive diplomatic transport typically fall under it. Exemption 7 protects law enforcement records when disclosure could interfere with proceedings, reveal confidential sources, expose techniques, or endanger someone. Surveillance flights and operations by the FBI, DEA, and Customs and Border Protection are commonly withheld on those grounds.
Pilot Logbooks and Personal Data
A pilot’s personal logbook is a private document. The FAA does not collect individual pilot flight time records, and personal logbooks aren’t accessible through FOIA or any public database. The FAA’s Pilot Records Database, used by air carriers during hiring, is specifically exempt from FOIA disclosure except in narrow circumstances such as criminal investigations or safety concerns.7Federal Register. Pilot Records Database
What is public is the FAA’s Airmen Inquiry database, which lets anyone search a certificated pilot by name and see certificate type, ratings, and medical certificate information. It doesn’t display Social Security numbers, certificate numbers, or dates of birth, and pilots can opt out of having their address shown.8Federal Aviation Administration. Airmen Inquiry – Search Page
Maintenance Records
Federal regulations require aircraft owners to keep detailed maintenance logs, but those records must be made available only to the FAA, the NTSB, or law enforcement on request. The public has no right of access to them.9eCFR. 14 CFR 91.417 – Maintenance Records
State and Local Government Aircraft
When a governor, county sheriff, or municipal agency uses a government-owned aircraft, the flight logs for those trips are generally subject to state open records laws rather than federal FOIA. Every state has its own public records statute, with its own procedures, deadlines, fees, and exemptions. Requests go to the agency that operates the aircraft, and you’ll need to identify the specific aircraft or trip. Some states provide electronic records at no cost; others charge per-page duplication fees. State-level law enforcement flight records may be withheld under exemptions similar to the federal ones, especially for active investigations or surveillance.
