Part 77
Effortlessly handle FAA obstruction evaluation and airspace analysis with JDA Solutions. Utilize our tools and forms to ensure compliant and efficient assessments for all navigable airspace structures.
Obstruction Evaluation and Airspace Analysis:
All builders regardless of the structure must contend with planning, zoning and permitting requirements before construction starts. Whether your project is a new high rise building, construction crane, wind turbine or broadcast tower, structures must meet local and state height zoning ordinances as well as Federal height standards under the Code of Federal Regulations.
14 CFR Part 77 imaginary surfaces establish standards for determining obstructions in navigable airspace. These imaginary surfaces run out from the runway in a manner that reflects where aircraft are likely to fly while also accommodating unforeseen aircraft maneuvers. The height above the ground of the imaginary surface is lowest near the runway and increases at a distance from the runway. Away from airports, airspace begins at 200 feet above ground level.
Large structures, like communication towers and wind turbines, often exceed 200 feet in height and therefore are required to submit FAA Form 7460, Notice of Proposed Construction or Alteration. Structures shorter than 200 feet but located within 20,000 feet of a runway may also penetrate navigable airspace.
The FAA requires any proposed structure that meets certain criteria must be assessed against Part 77. Documents must be filed with the FAA for new structures so a determination can be made if the structure will be a hazard to air navigation.
All Services
Our documented track record of success is based on a simple but very effective process:
- Identify and assess the potential structure impact per 14 CFR Part 77 and Terminal Instrument Procedures (TERPS).
- Provide information and reports that are easy to understand.
- Develop mitigation strategies.
- Involve key decision makers.
- Present viable solutions.
- Pursue approval and implementation through the FAA 7460 application process.
Avoid unnecessary redesign costs and construction schedule delays by determining early in the planning phase the building height the FAA will approve. An FAA DNH will also be helpful in easing any concerns of local permitting and approval authorities. Not all municipalities make it clear that FAA review and approval is necessary until late in the permitting process. For most builders, finding out late that the FAA hazard review is required can have a costly impact on your project.
