Why eVTOL Aircraft Need a Digital Access Layer Before Urban Air Mobility Can Scale
As electric vertical takeoff and landing aircraft move closer to commercial deployment, the missing layer is not just aircraft design — it is controlled access, corridor coordination, and trusted transition-volume management.

OpenWhy I am building VHS
A note from the founder on why the road system for the sky needs to exist before the air taxis arrive.
OpenThe current VHS prototype includes two connected layers. A verified, deterministic coordination core implements reservation, readiness, conflict, transition-volume, and access-decision behavior. An investor-facing visualization consumes the versioned, published data contract produced by that coordination layer — the same contract intended for third-party integrators.
The visualization demonstrates four scenarios: Normal Access Granted, Conflict Hold and Release, Emergency Priority, and Reservation Conflict Rejected.
Neither layer is a certified or deployed aviation system. Integration is designed around open, published standards so that any compliant manufacturer, operator, vertiport, or future UTM-compatible system can participate.
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.
VHS currently includes two connected prototype layers. The public visual prototype demonstrates normal access, conflict hold and release, emergency priority, dashboard visibility, and inside-aircraft status concepts. Separately, M.K.K. Enterprises has developed a tested technical software core and locally verified API implementing the underlying reservation, readiness, conflict, transition-volume, and decision logic.
Neither prototype is a certified or deployed aviation system. VHS is not connected to live aircraft, does not replace air traffic control or regulatory authority, and has not yet completed independent operational validation.
