AirIndex RiskIndex · Sample Assessment

This heliport is FAA-approved.
It may not be operationally viable.

Standard facility evaluations check regulatory compliance. AirIndex evaluates three layers most assessments miss — data reliability, physical feasibility, and operational exposure.

What the assessment found
Data Reliability (DQS)
Low
FAA record activated 1964 — built under standards that predate modern TLOF/FATO terminology. Recorded pad dimensions may not represent what current standards define. Position data last verified 2017.
Regulatory Compliance
Pass
Active FAA NASR 5010 registration. State enforcement posture rated strong. No major registration deficiencies on file.
Dimensional Constraint
Constrained
Current pad meets legacy heliport standards (1.5D). Does not meet EB-105A eVTOL dimensional requirements (2D load-bearing FATO). Expansion gap: 70 ft beyond recorded pad for eVTOL operations.
Obstruction Environment (OES)
Elevated
Multiple structures above 100 ft within 500m. Buildings in the prevailing wind path create potential channeling. 8:1 approach surface analysis identifies penetration risk.
Operational Exposure (OEL)
High
Hospital rooftop configuration with likely proximity to HVAC intake systems. Surrounding structures may create airflow disruption and exhaust recirculation not captured in FAA records.
This site passes compliance. That does not mean it is operationally viable.
Most facility decisions today rely on FAA records that are often incomplete or outdated. 40% of heliports in tracked markets were built before the FAA established the dimensional terminology still in use. AirIndex structures that evaluation before capital or underwriting decisions are made.
