VHS Framework
A PSU-aligned transition-volume access layer for future eVTOL corridor entry and exit.
VHS is designed as a PSU-aligned transition-volume access layer. In FAA Urban Air Mobility framework discussions, a Provider of Services for UAM, or PSU, is a broader service/data role supporting UAM operations. VHS is narrower and focused: it addresses the access-control problem around certified access nodes, transition volumes, reservation windows, conflict holds, corridor entry/exit, and emergency priority.
Not the entire stack. The access layer.
Build aircraft.
Build physical infrastructure.
Govern aviation safety.
Move passengers, cargo, or emergency assets.
VHS focuses on the access layer between certified access nodes and structured aerial corridors. It does not replace any of the roles above. It coordinates who may enter, when, and under what conditions — so that the rest of the ecosystem can operate safely and predictably.
PSU-aligned, not an official PSU today.
VHS is PSU-aligned, but it should not be described as an official PSU today. VHS is a prototype-stage concept that could become a PSU-compatible module, specialized access-control service, or transition-volume coordination layer within future UAM/AAM operating frameworks.
The space between the node and the corridor.
The critical bottleneck is the space between the access node and the aerial corridor. VHS is designed to manage who gets access, when access is granted, when an aircraft must hold, when emergency priority applies, and how the network sees unauthorized conflicts.
Clear boundaries.
Future possibilities.
Focused on a specific subproblem.
VHS sits adjacent to UTM, USS, PSU, vertiport management, fleet operations, and city planning tools. The VHS focus is narrower: transition-volume access around certified access nodes.
VHS does not claim to replace any of these systems. It is designed to complement them by solving a well-defined coordination problem at the boundary between ground infrastructure and aerial corridors.
A narrower, access-focused layer within the UAM ecosystem.
VHS is designed as a PSU-aligned transition-volume access layer. In FAA Urban Air Mobility framework discussions, a Provider of Services for UAM, or PSU, is a broader service/data role supporting UAM operations. VHS is narrower and focused: it addresses the access-control problem around certified access nodes, transition volumes, reservation windows, conflict holds, corridor entry/exit, and emergency priority.
VHS is not replacing FAA, air traffic control, aircraft operators, or vertiport operators. VHS is a prototype-stage concept intended to support future coordination and visualization around structured aerial access.
VHS is not FAA-approved, certified, or deployed. References to PSU terminology describe alignment with publicly discussed FAA UAM concepts, not regulatory status.
The current VHS prototype is an investor-facing demonstration of the operating logic. It visualizes access granted, conflict hold/release, and emergency priority scenarios. It is not yet a live aviation system, certified product, or deployed reservation engine.
