There is a whole host of uses for the aviation data available from this site, the planned use should dictate which download you use. There are three data sets, these are available in three formats. You can contact us and request other formats, if you would like the data in JSON or pipe delimited formats we can oblige at no extra cost.
You can read about what is in each data set on the about page, there we give more specific examples of how the data can be used. But below we list a number of examples for use cases for the aviation enthusiast, however you might have a better idea of how to use the data. Some of the suggestions below will require multple downloads, especially where there is a need to build a historical file.
To assist you in this we make the historical “deregistered aurcraft file” free to download. This file has a wealth of historical information and contains historical data on over 380,000 aircraft. The deregistered file is alligned with the data files, it is refreshed on a monthly basis along with all the other data sets.
Spotting & Tracking Aircraft
-
Cross-reference tail numbers seen at an airport or airshow with registry data to identify the aircraft’s make, model, year of manufacture, and owner.
-
Build a personal database of planes you’ve spotted and add registry details for completeness.
-
Use the data to identify whether a sighted aircraft is privately owned, corporate, or part of a fleet.
Historical & Fleet Research
-
Study how many examples of a particular aircraft type are still registered (e.g., DC-3s, Beechcraft Starships, classic Piper Cubs).
-
Track registrations of retired types and compare to production totals.
-
Investigate long-term trends in aviation—like the growth of certain categories (e.g., light sport aircraft, experimental homebuilts, drones).
Mapping & Geographic Analysis
-
Plot aircraft by state, county, or city of registration to see where certain aircraft are concentrated.
-
Compare density of helicopters in big cities vs rural areas, or seaplanes near lakes and coastal regions.
-
Create heat maps of general aviation hubs across the U.S.
Ownership Insights
-
Identify corporations or flight schools that operate fleets by spotting repeated owners.
-
For enthusiasts of vintage warbirds, find which museums, groups, or individuals are registered owners of rare types.
-
Track how ownership of specific tail numbers changes over time (if historical registry snapshots are saved).
Performance & Technical Curiosity
-
Analyze trends by engine type (turboprop vs jet vs piston) or aircraft category (glider, balloon, rotorcraft).
-
Compare registrations of experimental vs certified aircraft.
-
Study how engine manufacturer popularity shifts over time.
Photography & Plane Spotting Prep
-
Before visiting an airport, pull a list of all aircraft based at that field (many are registered with their base city/airport).
-
Prioritize spotting rarer types or unusual liveries.
-
Cross-reference registration with online flight trackers for real-time activity.
Community & Hobbyist Projects
-
Build searchable apps or databases for fellow enthusiasts.
-
Create infographics, timelines, or charts about U.S. civil aviation.
-
Participate in crowd-sourced aircraft history projects, contributing registry-verified information.
Comparisons with International Registers
-
Contrast the U.S. registry with other nations’ registries to see which aircraft are disproportionately popular in America.
-
Track imported/exported aircraft (e.g., European gliders now flying in the U.S.).
