Submission Summary
The Multimodal Grid Initiative is an independently developed digital-command framework that links air, sea, and ground mobility through standardized Digital Front Doors for every vertiport.
Proposed for appraisal under FAA eIPP Notice 697DCK-25-R-00445, the concept demonstrates how verified public-facing data layers can enhance operational safety, coordination, and transparency across America’s emerging Advanced Air Mobility (AAM) ecosystem.This visualization presents a scalable model for real-time situational awareness connecting aircraft status, ground access, and weather data into one trusted interface.Core ObjectivesStrengthen airspace awareness for pilots, regulators, and emergency services.Integrate aviation, maritime, and urban-mobility coordination.Display transparent, verified operational information to build public trust.Serve as a national digital blueprint replicable across AAM corridors.

Safety & Data IntegrationEach vertiport maintains a Digital Front Door showing:Live vertiport status and aircraft movements.Active NOTAMs, advisories, and weather overlays.Intermodal links between air, sea, and ground transport.Automated emergency notifications shared across municipal networks.By connecting these portals into a unified grid, the system improves airspace situational awareness for pilots, dispatchers, and regulators.
The framework supports FAA and NASA AAM priorities including Safety Management System (SMS) integration and data interoperability between public and private operators.
In simulated use, it reduces conflicts, improves emergency routing, and turns complex airspace data into an accessible public resource.

Public Benefit & TransparencyThe initiative advances the FAA’s commitment to operational openness by making AAM data accessible to citizens and communities.
Through Digital Front Doors, anyone can:View verified vertiport status and safety metrics.Understand airspace activity without specialized software.Receive alerts for weather or temporary closures.Track connections between air taxis, ferries, and ground transit.This visibility reduces misinformation and concerns about noise or safety while reinforcing confidence in sustainable next-generation flight.

Scalability & National ReplicationBuilt on open standards, the Multimodal Grid can link local datasets nationwide while maintaining FAA and NASA AAM data-exchange compatibility.Potential Demonstration HubsNew York City Airspace Grid – urban air corridors and waterfront access.Los Angeles Corridor Network – coastal and inland vertiport nodes.Dallas / Fort Worth AAM Testbed – integrated emergency and logistics ops.Miami / South Florida Grid – maritime-air coordination.Chicago / Great Lakes Corridor – cargo and passenger integration.Each deployment can scale from a city pilot to a national network of interoperable vertiports.

Partnerships & ReadinessPositioned for collaboration with public agencies, private operators, and research institutions focused on AAM integration.Alignment OpportunitiesFAA AAM Integration Office – policy and data-exchange coordination.NASA AAM Mission and Vertiport Standards Working Groups – validation.Municipal Departments of Transportation – emergency response simulation.Private AAM OEMs – real-time flight-data testing.Academic Partners – independent evaluation of scalability.Readiness Level: Digital Demonstration (TRL 3–4) | Fully conceptual visualization complete | Scalable using open-data protocols.

West Coast Grid — Los Angeles CorridorThe Multimodal Grid Initiative expands to the West Coast through the L.A. Grid, connecting Santa Monica, Inglewood, and Orange County under one unified digital framework.This corridor demonstrates how verified Digital Front Doors at each vertiport can enhance safety, transparency, and multimodal coordination across the national air mobility network.Each vertiport node provides real-time visibility for passengers, operators, and regulators—supporting FAA eIPP goals for scalable, interoperable airspace integration and public engagement.The L.A. Grid reflects America’s westward expansion of the Advanced Air Mobility ecosystem: interoperable, open, and ready to serve commercial, emergency, and cargo operations across key California hubs.
