SUPPORTING STATEMENT
National Flight Data Center (NFDC) Web Site
2120-0754
INTRODUCTION
This information collection is submitted to the Office of Management and Budget
(OMB) to request a renewal of the information collection entitled “National Flight
Data Center Web Site”.
Part A. Justification
1. Circumstances that make collection of information necessary.
49 USC 40103, “Sovereignty and Use of Airspace,” authorizes and directs the FAA to
develop plans and policy for the use of the navigable airspace. The National Flight Data
Center (NFDC) is the authoritative government source for collecting, validating, storing,
maintaining, and disseminating aeronautical data concerning the United States and its
territories to support real-time aviation activities. The information collected ensures the
safe and efficient navigation of the national airspace. The information collected is
maintained in the National Airspace System Resources (NASR) database which serves
as the official repository for NAS data and is provided to government, military, and
private producers of aeronautical charts, publications, and flight management systems.
FAA Order 1100.332, Chapter 4, paragraph 2f oversees Mission Support Services
activities in the following areas: airspace management and redesign, aeronautical
information management, mapping, charting, planning, performance-based navigation,
and instrument flight procedures.
This information collection supports the Department of Transportation’s strategic goal of
safety.

2. How, by whom, and for what purpose is the information used.
The information is distributed via the National Flight Data Digest (NFDD), a daily
electronic (.pdf) publication available at no charge to the general public, government,
military, and private producers of aeronautical publications.
(https://www.faa.gov/air_traffic/flight_info/aeronav/aero_data/NFDD/) The information is
used to update government, military, and private aeronautical database, charts,
publications, and flight management systems. This includes Airport data for the
following: facility use, runway information, traffic pattern altitude, right traffic,
deactivation, and general remarks. Reporting of this information in mandatory, i.e.

1

airport operators are required to submit any changes to their facilities that might appear
on aeronautical charts or publications. This is considered to be reporting of information
vs. recordkeeping or disclosure. Information is collected on a continual basis.

3. Extent of automated information collection.
100% of the data is collected electronically via the NFDC Web Site at
https://www.faa.gov/air_traffic/flight_info/aeronav/aero_data/. (While this link leads to
the website, passwords are required to access all entry forms to ensure the integrity of
the data collected.) The collection of the information involves the use of automated
forms that are completed and submitted electronically online, by an assortment of data
providers. Once submitted, the data is validated, stored, and disseminated to the public
over the Internet via the NFDD, as described above.

4. Efforts to identify duplication.
There is no duplication. NFDC is designated as the single authoritative source within
the FAA to collect, validate, store, and disseminate aeronautical data.

5. Efforts to minimize the burden on small businesses.
The implementation of the NFDC web site minimizes the burden on small entities by
eliminating the need to fax or mail changes/updates to aeronautical data by permitting
the information to be submitted electronically through the online site.

6. Impact of less frequent collection of information.
The collection of aeronautical data is a continual process. Not having the capability to
conduct the collection would result in data gaps on aeronautical databases, charts,
publications, and flight management systems. This would adversely affect the safety of
the NAS. Conducting the collection on as less than continual basis would result in
obsolete data being portrayed on aeronautical databases, charts, publications, and flight
management systems. This would adversely affect the safety of the NAS.

7. Special circumstances.
There are no special circumstances that would require this collection to be conducted in
a manner inconsistent with the points presented in 5 CFR section 1320.5(d)(2)(i)(viii).

8. PRA Federal Register Notice:

A Federal Register Notice published on April 27, 2020 (vol. 85, no. 81, pages 2342823429) solicited public comment. No comments were received.

9. Payments or gifts to respondents.
No payments or gifts are provided to respondents.

10. Assurance of confidentiality:
No assurance of confidentiality is provided.

11. Justification for collection of sensitive information:
No sensitive information is collected.

12. Estimate of burden hours for information requested:
Aeronautical Data Change (ADC):
Total U.S. public civil airports: 5,092 respondents. NFDC receives approximately 5,773
ADC forms annually. Each form takes approximately 20 minutes to complete.
Therefore the annual hourly burden is approximately 1,924 hours. The annual hourly
burden prior to this renewal was estimated at 1,853 hours. The burden was estimated
by taking the actual total number of responses in 2019 multiplied by the average
response time.

Aeronautical Chart Changes (ACC):
Total U.S. public civil airports: 5,092 respondents. NFDC receives approximately 936
ACC forms annually. Each form takes approximately 20 minutes to complete.
Therefore the annual hourly burden is approximately 312 hours. The annual hourly
burden prior to this renewal was estimated at 254 hours. The burden was estimated by
taking the actual total number of responses in 2019 multiplied by the average response
time.

15. Explanation of program changes or adjustments.
The estimate of burden has increased slightly for both forms from the previous renewal
(71 hours for the ADC form and 58 hours for the ACC form). This is a result of the forms
becoming more widely known and used.

16. Publication of results of data collection.
NFDC collects the data received from the web site forms and this data is populated into
the National Airspace System Resources (NASR) data base. In turn, NASR produces a
daily output report called the National Flight Data Digest (NFDD). The NFDD is
available to the general public at no cost via this website:
https://www.faa.gov/air_traffic/flight_info/aeronav/aero_data/NFDD/ . In addition to the
daily output, NASR subscriber files are compiled each 28 day cycle and are
disseminated to the general public via the following website:
https://www.faa.gov/air_traffic/flight_info/aeronav/aero_data/NASR_Subscription/
No data is printed or sent out of the website.
