Preliminary Screening
FAA Part 77 fixed-wing surface analysis software
Analyze Part 77 surfaces before project decisions harden
Clear Path supports detailed preliminary Part 77 fixed-wing surface analysis by checking supported primary, approach, transitional, horizontal, and conical surfaces, applicability, and elevation comparisons before teams move into formal FAA review paths.
- Review supported Part 77 fixed-wing surface outcomes without treating the analysis as a formal FAA determination.
- Separate evaluated, not applicable, and not-evaluated results.
- Keep validation coverage and non-certification language attached to the report path.
Who this is for
Airport sponsors, planners, engineers, developers, consultants, and municipal review teams.
- Teams evaluating proposed objects near civil airport runway environments.
- Consultants who need a preliminary Part 77 support exhibit.
- Sponsors and planners who need early issue spotting before formal FAA coordination.
What Clear Path does
Clear Path supports preliminary obstruction screening, protected-surface visualization, and report-ready planning context for supported criteria paths.
What Clear Path helps with
- Run supported FAA Part 77 fixed-wing surface analysis using structured runway and object inputs.
- Identify likely primary, approach, transitional, horizontal, and conical surface penetrations.
- Review validation coverage and criteria support before relying on a screening path.
What Clear Path does not do
- Does not issue FAA, DoD, airport sponsor, engineering, surveying, legal, or other official approval.
- Does not replace formal FAA OE/AAA filing, airport coordination, sponsor review, DoD review, or professional engineering judgment.
- Does not treat unsupported, dependency-gated, or partial criteria as clearance, compliance, or a no-hazard finding.
Supported workflow summary
Confirm the airport/runway context and selected runway end.
Run Part 77 analysis and review clear, boundary, violation, and not-evaluated outputs.
Use the report as planning support before FAA coordination, not as a formal determination.
Review before relying on results
Clear Path outputs are preliminary screening and decision-support materials. They do not replace FAA, DoD, airport sponsor, command, engineering, surveying, legal, safety, environmental, or other official approval processes.
Part 77 logic is tested against synthetic and real-airport validation coverage, while unsupported or dependency-gated cases remain labeled instead of being promoted to clearance.
