Operational progression
Each layer earns the next.
Each milestone extends the system's operational understanding, moving from runway interpretation toward surface logic, traffic awareness, and full controller behavior.
Development initiated in March 2026
Telemetry & Runway Dataset
Live simulator telemetry, runway references, threshold anchoring, and environmental alignment established the raw operational base.
Navigation Geometry Core
Bearing logic, haversine distance, cross-track computation, heading normalization, and deterministic runway-relative geometry.
RIS Landing Resolution Core
RIS (Runway Intelligence System), inside RISEngine, resolves touchdown, rollout, runway occupancy, and vacated-runway continuity through deterministic state interpretation.
Approach Corridor & Stability
Corridor adherence, directional consistency, threshold coherence, and stable approach interpretation before runway entry.
Surface Operational Expansion
Active development extends runway understanding into taxi, lineup, hold-short interpretation, and departure-state continuity.
Surface Intent
Taxi-state continuity, hold-short interpretation, lineup recognition, and runway entry logic.
Departure Semantics
Departure-roll identification and threshold-based takeoff state interpretation.
Runway Continuity
Persistent aircraft-state transitions without breaking runway ownership reliability.
Traffic Intelligence
Once surface intent stabilizes, runway operations expand into traffic interaction and conflict anticipation.
Occupancy Anticipation
Predictive runway occupancy awareness before threshold conflict occurs.
Arrival Sequencing
Spacing logic between aircraft approaching the same runway environment.
Instruction Decision Engine
Priority resolution, runway authority, and state-derived clearances.
Controller Layer
Higher-level ATC behavior emerges only after aircraft-state interpretation reaches full operational consistency.
Controller Logic
Procedural ATC decisions derived from deterministic aircraft-state understanding.
Phraseology
Voice interaction introduced after state reliability matures.
Multi-Aircraft Behavior
Coherent operational logic across simultaneous arrivals, departures, and surface movement.
