Air Traffic Activity Data System (ATADS) Guide

The ATADS (Air Traffic Activity Data System) database lets you look up the number of operations (take-offs and landings) at any airport. Some of the data is subject to change. Typically, the data is updated on the 20^th of each month with the previous month’s information.

This guide provides instructions for generating:

An operations report for any single airport
A ranking report that compares total operations for a group of airports

To generate an operations report for an airport

Suppose you’re wondering how many take-offs and landings happened at Chicago O’Hare Airport from 2005 to 2007. Follow the steps below to find the answer.

Print this page to have a copy of the instructions available as you follow these procedures.
Navigate to the ATADS home page: http://aspm.faa.gov/main/atads.asp
Click Towers.
In the Find box, type the three-letter airport code for O’Hare (ORD), or, select O’Hare in the list of airports. (For a list of all airport codes, visit http://www.oag.com).
Select the Yearly option.
Next to From, select 2005, and next to To, select 2007. (To look up data for one year, use the same year in both boxes. You can also look up data by month, day, or a date range.)
Click Run.

Your query generates the following “Period Report”:

The numbers in the report represent all “operations” — both landings and take-offs — for the time period you requested.

Here are the meanings of the column heading abbreviations:
- AC — Air Carrier
- Air Taxi (AT) — aircraft designed to have a maximum seating capacity of 60 seats or less or a maximum payload capacity of 18,000 pounds or less carrying passengers or cargo for hire or compensation.
- GA — General Aviation
- MIL — Military
Important: To determine the number of flights, divide the total number of operations in half.
To start a new query, close the Report window. Then click Change Filter.
