CONDITIONALConversion feasibility · four readings, one line each
Obstruction screen
Clear
No obstructions within 0.5 nm on the FAA obstacle file.
Geometry
Requires 8 feet of expansion
Recorded pad side 92 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.
100 ft · eVTOL FATO92 ft
The recorded pad is 8 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.

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.
