eVTOL readiness

INFEASIBLE WITHOUT REMEDIATIONConversion feasibility · four readings, one line each
Obstruction screen
Severe
High obstacle within 0.5 nm conflicts with the expanded footprint and the 8:1 approach surface.
Geometry
Requires 67 feet of expansion
Recorded pad side 33 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
Infeasible without remediation
A high obstacle conflicts with the expanded footprint. Remediation or a different site.
100 ft · eVTOL FATO33 ft
The recorded pad is 67 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

100 ft
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.
