| In administering Title 14 of the Code of Federal Regulations
Part 77, the prime objectives of the FAA are to promote air safety
and the efficient use of the navigable airspace. To accomplish
this mission, aeronautical studies are conducted based on information
provided by proponents on an FAA Form 7460-1, Notice of Proposed
Construction or Alteration.
Advisory Circular 70/7460-1M, Obstruction Marking and Lighting,
describes the standards for marking and lighting structures
such as buildings, chimneys, antenna towers, cooling towers,
storage tanks, supporting structures of overhead wires, etc.
Improved features include:
Important notes for user preview:
- Intuitive user interface
- Additional account security
- Smart programming for dynamic data entry
- Dynamic search options and features
- Improved case processing for new cases (7460-1 forms)
- Preview data is for familiarization only.
- Saved data is not submitted to the FAA.
- Preview data will not be available in the upcoming "live" modernized OE/AAA site.
- The FAA will be retiring the legacy OE/AAA system in the near future. In preparation for the upcoming transition, users are encouraged to take advantage of the OE/AAA Preview to familiarize themselves with the modernized features, functions and layout.
OE/AAA Filing Process
If your organization is planning to sponsor any construction
or alterations which may affect navigable airspace, you must file a Notice of Proposed Construction or
Alteration (FAA Form 7460-1)
either electronically via this website or manually with the FAA.
File forms 7460-1 and 7460-2 electronically
via this website - New
E-filing your proposal is preferred because
- It's the fastest, most accurate method to submit to the FAA and immediately assigns an aeronautical study number to your case.
- It establishes an electronic communications link with FAA and allows you to obtain project status and notifications directly from this site.

Landing Area Proposal data collection has been disabled in OE/AAA. Please use the FAA's Airport Data and Information Portal (ADIP) to submit all your future LAP/7480-1 applications: https://adip.faa.gov
Find the FAA
Airports Region / District Office having jurisdiction
over the airport on which the construction is
located, and file to that address.
Who Needs to File
The requirements for filing with the Federal Aviation Administration for proposed structures vary based on a
number of factors: height, proximity to an airport, location, and frequencies emitted from the structure, etc.
For more details, please reference 14 CFR Part 77.9.
Please click here to use the FAA's Notice Criteria Tool to determine if you meet the requirements to file notice of your construction or alteration
In accordance with 14 CFR Part 77.9, if you propose any of the following types of construction or alteration, you must file notice with the FAA at least 45 days prior to beginning construction:
- any construction or alteration that exceeds an imaginary surface extending outward and upward at any of the following slopes:
- 100 to 1 for a horizontal distance of 20,000 ft. from the nearest point of the nearest runway of each airport described in 14 CFR 77.9(d) with its longest runway more than 3,200 ft. in actual length, excluding heliports
- 50 to 1 for a horizontal distance of 10,000 ft. from the nearest point of the nearest runway of each airport described in 14 CFR 77.9(d) with its longest runway no more than 3,200 ft. in actual length, excluding heliports
- 25 to 1 for a horizontal distance of 5,000 ft. from the nearest point of the nearest landing and takeoff area of each heliport described in 14 CFR 77.9(d);
- OR any highway, railroad, waterway or other traverse way for mobile objects, of a height which, if adjusted upward as defined in 14 CFR 77.9(c) would exceed a standard of 14 CFR 77.9 (a) or (b);
- OR your structure will emit frequencies, and does not meet the conditions of the FAA Co-location Policy;
- OR your proposed structure will be in proximity to a navigation facility and may impact the assurance of navigation signal reception;
- OR any construction or alteration exceeding 200 feet above ground level, regardless of location;
- OR any construction or alteration located on an airport described in 14 CFR 77.9(d);
- OR filing has been requested by the FAA.
