Aviation Noise Complaint and Inquiry Response Portal | Index and Additional Information
Data Sources, References, and Notes
- The information presented here uses data collected from the ANCIR Portal and filtered to the last calendar year.
- Timing of Complaint Resolution - The number of complaints received may not equal the number worked within a given calendar year. Complaints received late in December 2024 may not be responded to until 2025, impacting year-end totals and response timing metrics.
- Nationwide complaints encompass all complaints for the calendar year.
- Regional office complaints are filtered to only that specific regional office for the last calendar year.
- Outstanding Complaints - Some complaints remain outstanding in specific regions. While this is a known issue, it is noted here for awareness and transparency.
- Regional complaints are categorized based on defined geographic boundaries. While the number of complaints within individual regional categories may vary slightly when compared to the broader national page view, these differences do not affect the overall total.
Nationwide
Total Complaints - Count of all complaints received by FAA within the stated timeframe.
Total Individuals Who Submitted Concerns - A count of distinct individual names received by FAA within the stated timeframe.
Treatment of Ambiguous or Misused Fields - Complaints involving misuse or unclear input in specific fields, such as airport codes entered inconsistently, were treated as if the field were left blank. This approach ensured that these entries did not distort rankings or data for specific sources but were still included in the overall count of complaints.
Non-Substantive Improvements - Minor adjustments were made to enhance the quality of life for report preparation. These changes improved functionality but did not alter the substantive content or outcomes of the report.
Noise Portal Responses
Inquiry Received Response – All complaints which received a response from the FAA. (This is the sum of the count of complaints whose Resolution field in ANCIR is “Final Response” added to the count of complaints whose Resolution field is “Response Provided - FSDO Safety Issue”.)
Received No Response (Response Not Requested) – Total of submitted complaints which did not request a response.
Received No Response (Repeat and Non-Qualifying) – Submitted complaints which did not qualify for a response based on FAA policy but requested a response.
Total Complaints Reviewed – Count of all complaints submitted to the FAA.
Individuals With More Than Seven Repeat Inquiries
Number of Repeat Individuals:
- Calculates the number of distinct individuals with more than seven inquiries in the ANCIR Portal.
- Names were counted and labeled as “Repeat” if there were seven or more from the same name or labeled “Not Repeat” if less.
- Blank name entries were removed, and the number of individuals was determined with a distinct count of names with the Repeat label.
- Handling Repeat Complainants - Repeat complainants were consolidated and marked as resolved in the reporting system to ensure accurate representation of unique complaints.
- Resolving Multiple Identifiers - Instances of serial complainants using multiple email addresses were identified and consolidated into a single entry to prevent duplication.
Repeat Complaints and Inquiries – Calculates the number of complaints created by individuals with more than seven inquiries in the ANCIR Portal.
Percentage of All Regional Inquiries:

- A count of all complaints was divided by complaints with the “Repeat” label.
