Urban Air Mobility vertiports occupy a category of civilian airspace that did not exist until the regulators wrote it. The airspace is civilian — passengers, scheduled service, commercial liability — but the geometry borrows from rotorcraft pads, the density borrows from metro-scale traffic, and the threat envelope borrows from both fixed- wing airport approach and contested low-altitude corridors.
This note describes how UAM Korea Tech reads the vertiport class and what the AVIX-AI Civil deployment actually does on a vertiport.
The geometry
A vertiport's protection envelope is not a runway approach cone. It is a stack of vertical funnels at the takeoff/landing surface, transitioning into a network of lateral approach corridors at lower altitudes than fixed-wing operations and at higher densities than rotorcraft.
Three geometric primitives matter:
- Vertical funnel — pad surface to ~150 m AGL, narrow, slow, high sensitivity to bird-strike interactions because the eVTOL is extremely close to the ground.
- Transition arc — 150 m to ~600 m AGL, the eVTOL is converting between vertical and lateral flight regimes; bird strike on a transitioning vehicle is a different aerodynamic problem from a fixed-wing departure.
- Cruise corridor — beyond ~600 m AGL, similar to traditional UAM cruise; the bird-strike problem here is closer to the fixed-wing case but at much higher operational density.
What AVIX-AI Civil does on a vertiport
The Civil deployment configures sensor placement to cover all three geometric primitives, profiles the local habitat (urban building microclimate creates surprisingly distinct bird patterns from the surrounding metro region), and publishes Animal-class entities into the vertiport operator's Lattice instance.
The key operational difference vs. an airport deployment is density correlation. On a vertiport, a single bird detection event is rarely a single-eVTOL question — it is a question about the next 4 to 12 inbound vehicles. AVIX-AI Civil exposes the correlation explicitly rather than letting the human operator guess.
Regulatory frame
K-UAM (Korean Urban Air Mobility) regulatory work currently treats bird-strike risk under existing civil aviation rules. The schema gap created by vertiport-class operations is recognised in working groups but not yet codified. We are open to contributing to the codification effort — see Engagement on the Solutions overview for the procedural options.
