Evidence hierarchy
- Regulator certification or approval
- Current manufacturer technical material
- Company filing or dated program update
- Credible reporting for schedule and program risk
From market claims to site requirements
Explore aircraft expected through 2031, separate certification evidence from announced timelines, and translate published dimensions into a preliminary Lemon Road facility envelope.
Screening only. Manufacturer claims and target dates are not guarantees of certification, delivery, site approval, or safe operation.
Lemon Road baseline
Actual site geometry
Select an aircraft and candidate to update its footprint against the parcel, mapped wetlands, buildings, terrain, trail, and stream constraints.
Regional screening
Range rings show straight-line manufacturer claims from the selected candidate. Airspace overlays identify coordination and restricted-area cautions—not legal routes.
Readiness windows
Company target dates are shown as uncertain windows beside a phased private-use development scenario. Neither track is a commitment.
FAA Part 157 normally requires notice at least 90 days before construction or a reportable change. County, fieldwork, utility, aircraft, and FAA schedules can overlap but remain independently uncertain.
Aircraft market
“Target year” is the latest sourced company objective—not a forecast. Use the evidence and confidence labels to distinguish delivered aircraft from concepts.
Operating concept
Configure the initial operation. The result combines published aircraft data, FAA EB 105A screening geometry, and current Lemon site evidence.
Preliminary design envelope
Private facility program
Explore planning-level charging loads and a phased set of facilities. Values reserve capacity for utility and concept review; they are not engineered sizes or final siting.
Side-by-side
Research record
Every aircraft record links to its supporting sources. Missing manufacturer values remain missing; the tool does not silently infer them.
Aircraft controlling dimension D is not propulsion reference diameter RD. FAA screening geometry cannot be completed when RD or aircraft-specific downwash data are unpublished. Part 103 ultralights are outside EB 105A’s formal scope.
Certification targets frequently move. Preorders, reservations, demonstration flights, and foreign approvals are not U.S. type certification. Lilium has ended; Supernal S-A2, CityAirbus, Overair, and Textron Nexus are not treated as active market entrants. Volocopter is distressed but active.
