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 55 feet of expansion
Recorded pad side 45 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.
The recorded pad is 55 ft short of the 100 ft footprint an eVTOL would need — shown to scale.

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.
IBC references NFPA 418 for rooftop facilities. Standalone fire code reference not confirmed.

Situations open at this facility1
mediumsuspect record with trafficopened 2026-09-14 · situation-rules-v1
Record flagged as possibly mislocated, with 4 observed eVTOL flights in the last 30 days at 1 endpoint within 15 nm (nearest KDFW, 9 nm): aircraft may be routed to a position the record does not support.
Situations are rules-based inferences across the obstruction, observed-operations and record layers, re-evaluated nightly; each carries its evidence and closes when the condition no longer holds.

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.
