Have you ever wondered how many planes go over “your runway” in a single day? How many consecutive hours of noise and pollution you’re exposed to on a daily basis? How often the city attempts to shift flight paths to give residents a break–or doesn’t? Well we have, and we did something about it to find out and share it with you.

FAiR obtained this information from CDA with many Freedom of Information Act (FOIA) requests and compiled operations data for every single arrival and departure into and out of O’Hare from January 2013 (pre-change in flight patterns) through August 2015.**

The data has been sorted into daily tables (Arrivals or Departures) for each month so you can see exactly how many planes interrupted you and at what hours of the day. Especially of interest are the Fly Quiet hours, shaded in green and red for the “shoulder hours” (10-11 p.m. and 6-7 a.m.). Caveat: It’s a lot of information, but we think you’ll find it illuminating and it should be something you immediately bring to the attention of your elected officials. They should NOT be okay with what the city continues to impose on us with this bad plan. And the city will continue to impose more, as the goal is to increase capacity (which means operations equalling total number of flights) with the full build-out of the OMP. That means Only More Planes, noise and pollution in our skies.

Here’s what to do if you want to take a look at this information:
1. Know (or Find) your runway. You can do this by searching Google Maps for your address, then zooming out and adjusting the screen until you see O’Hare’s runway layout and your address. Check the runway layout against FAiR’s runway primer (click here) and see which runway your home lines up with (or between which two runways it lies).

2. Click here to access all data from January 2013-August 2015.

**Note: CDA was unable to provide complete data or provided duplicate data on some days. These have all been noted. The data contains some anomalies in runway designations, evident in single digit arrivals and departures on seldom used or closed runways, or operations with no runway designation which are totalized in the “Blank” column. It is unknown if these errant designations indicate an actual operation on another runway, therefore all aircraft operations have been counted in order to correlate to the raw data. However, the “Blank” tallies create a perpetual imbalance in operations favoring departures.

3. Choose a year (2013, 2014, or 2015)

4. Choose a month’s “Arrivals” or “Departures” (ex: 10-2013 ORD Arrivals)–depending on what causes you the most disruption. For many of you, it may be both–so you’ll choose one at a time.

5. You’ll now be in a document with a spreadsheet for each day of the month listing the runways at the top and the hours of the day from midnight (0:00-1:00) to midnight (23:00-24:00). Find your runway column (ex: 27L) and scroll through to see how many planes you experienced during specific hours of each day. The bottom row shows the total number of planes on “your runway” for a given day. For example, in October 2013, 27L had more than 400 flights a day on 16 days. On many of those days, the planes continued for sixteen hours straight. This is unacceptable! We deserve better!

What can you do with this information?

  • Write to all of your elected officials telling them that this cannot stand. If you are experiencing this many flights now, what will happen when demand goes up and two runways that could provide relief–especially overnight–are gone? Who is accountable to the people who live under the flight paths?
  • Use this new information to appeal your taxes at the Board of Review. Appeal decisions are in the mail and several members have received their results. Use this evidence when you submit your form and at a Board of Review hearing to show the exact impact this has on your home and its value.
  • Ask the Mayor and Commissioner Evans what is a reasonable and tolerable number of flights per day for a person to listen to and breathe in the emissions. Ask them if “your number” is a quality of life they would accept for themselves, their families, their children and grandchildren, their elderly relatives.

Knowledge is power, FAiR friends, and the more we arm ourselves with it, the more this bad plan reveals itself. Use this information to assert your voice, to assert your right as a citizen to have a say about your home, health, and property, and to tell the city that enough is enough. It is time for the Mayor and Commissioner to stand with the people.

Go FAiR!
