eVTOL readiness
CONDITIONALConversion feasibility · four readings, one line each
Obstruction screen
Clear
No obstructions within 0.5 nm on the FAA obstacle file.
Geometry
Requires 60 feet of expansion
Recorded pad side 40 ft against a 100 ft eVTOL FATO.
Structural FATO
Unverified
The full 100 × 100 ft FATO must be load-bearing. The FAA does not record structural capacity, so no record can confirm it.
Overall
Conditional
Obstruction screen passed. Geometry and structural capacity remain open. Site validation required.
The recorded pad is 60 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

FAA EB-105 vertiport pattern — 2× a ~50 ft eVTOL controlling dimension, plus a 125 ft safety-area side.
Load-bearing FATO
100 × 100 ft must be structural
No heliport precedent — typically the binding gate for rooftop and hospital pads.
Measured against FAA pad geometry and federal FATO sizing (EB-105). The obstruction screen is the only reading the engine verdict rests on; geometry and structural capacity are stated separately and never folded into it. A dimensional pre-screen — site-level validation required, and independent of the underwriting risk score.

3Physically verifiedGround Truth capture
Obstructions, exact FATO geometry, surface condition, and downwash exposure require a physical Ground Truth capture — not shown above as measured. A field verification completes the record and writes the measured truth to this facility’s authority.
This page is the public data-integrity record. The full RiskIndex assessment — Q1–Q5 compliance, dimensional / FATO analysis, an underwriting-grade risk score, peer benchmark, and a sealed Site Intelligence Report — is available on request.
