✈️ RTT/Inside ATC Phase‑1 Integration Guide

Operator + Developer Edition

📘 Purpose of This Guide#

This document provides a Phase‑1 integration pathway for introducing the vetted RTT/Inside variant into existing Air Traffic Control (ATC) systems without modifying core surveillance, fusion, or safety‑critical automation stacks.

Phase‑1 focuses on:

  • Non‑intrusive overlays
  • Middleware augmentation
  • Predictive resonance‑time insights
  • Operator‑visible improvements
  • Zero‑risk integration with legacy systems

This allows ANSPs (Air Navigation Service Providers), military ATC, and Space Force operations to evaluate RTT/Inside’s benefits before committing to deeper stack integration.

1. 🧭 Overview of Phase‑1 Integration#

🎯 Goals#

  • Add RTT/Inside predictive metrics to existing track data
  • Display resonance‑aware overlays on current ATC screens
  • Improve operator situational awareness without altering SOPs
  • Enable A/B testing in simulation and live shadow mode
  • Prepare for Phase‑2 (automation integration) and Phase‑3 (full stack redesign)

🧩 Non‑Goals#

  • No changes to radar/ADS‑B hardware
  • No changes to fusion engines
  • No changes to separation minima
  • No changes to certified automation logic

Phase‑1 is decision‑support only, not safety‑critical.

RTT/Inside subscribes to fused tracks and publishes augmented tracks with resonance‑time metrics.

3. 🔧 Developer Integration Steps#

3.1 Subscribe to the Track Bus#

Our ATC system already publishes fused tracks via:

  • ASTERIX categories
  • Protobuf messages
  • JSON over WebSocket
  • Proprietary middleware

RTT/Inside middleware needs read‑only access.

Example (TypeScript‑style pseudocode)#

subscribeTracks((tracks: Track[]) => {
  rttMiddleware.process(tracks);
});

3.2 Compute RTT/Inside Metrics#

The RTT/Inside engine computes:

  • Corridor Stability Score (0–1)
  • Drift Risk Index (0–1)
  • Conflict Resonance Index (0–1)
  • Predictive Ghost Positions
  • Advisory Level (NORMAL / WATCH / ALERT)

Example RTT/Inside engine call#

const rtt = rttEngine.computeMetrics(track, neighbors);
return { ...track, rtt };

This produces an AugmentedTrack object.

3.3 Publish Augmented Tracks#

Publish to a new topic such as:

  • tracks.rtt
  • augmented.tracks
  • rtt-inside.overlay

Example#

publishAugmented(augmentedTracks);

This keeps RTT/Inside logically separate from certified systems.

3.4 Render Overlays on Existing Displays#

The overlay module reads augmented tracks and draws:

  • Stability‑colored paths
  • Advisory badges
  • Predictive ghost positions
  • Drift contours

Example overlay logic#

const style = buildOverlayStyle(augmentedTrack);
 
drawTrackPath(ctx, track, style.pathColor);
drawLabelBadge(ctx, track, style.labelBadge);
drawGhosts(ctx, style.ghostPositions);

This is non‑intrusive: if RTT/Inside is offline, the overlay simply doesn’t draw.

4. 🧑‍✈️ Operator‑Facing Features#

4.1 New Visual Elements#

🟢 Corridor Stability Colors#

  • Green: highly stable
  • Blue: normal
  • Amber: watch
  • Red: alert

👻 Predictive Ghost Positions#

Shows where the aircraft is likely to drift over the next 10 minutes.

🔺 Resonance Drift Indicators#

Subtle arrows or contours showing directional drift pressure.

🏷️ Advisory Badges#

  • NORMAL
  • WATCH
  • ALERT

These appear on the aircraft label.

4.2 Operator Benefits#

✔️ Earlier awareness of emerging conflicts#

Controllers see drift before it becomes a conflict.

✔️ Smoother sequencing#

Stability scoring helps identify the best candidates for speed control or vectoring.

✔️ Reduced cognitive load#

The system visually highlights where attention is needed.

✔️ Better coordination with Space Force#

Air + space tracks share a unified resonance‑aware model.

✔️ Zero change to SOPs#

Controllers continue using existing procedures; RTT/Inside simply enhances awareness.

5. 🧪 Testing & Validation#

5.1 Simulation Mode#

RTT/Inside can run in:

  • Replay mode (historical traffic)
  • Shadow mode (live traffic, not visible to pilots)
  • Training mode (synthetic scenarios)

This allows ANSPs to validate:

  • Stability scoring accuracy
  • Drift prediction quality
  • Operator workload impact
  • False positive/negative rates

5.2 Success Criteria#

A Phase‑1 deployment is considered successful when:

  • Operators report improved situational awareness
  • Drift predictions match real‑world outcomes
  • No interference with certified systems
  • Overlay performance meets latency requirements
  • No increase in controller workload

6. 🛠️ Example Code Snippets (Developer‑Ready)#

6.1 RTT/Inside Middleware Skeleton#

export class RttMiddleware {
  private engine = new RttEngine();
 
  constructor(subscribe, publish) {
    subscribe((tracks) => {
      const augmented = tracks.map(t => {
        const neighbors = tracks.filter(n => n.trackId !== t.trackId);
        const rtt = this.engine.computeMetrics(t, neighbors);
        return { ...t, rtt };
      });
      publish(augmented);
    });
  }
}

6.2 Overlay Style Builder#

export function buildOverlayStyle(track: AugmentedTrack) {
  const { corridor_stability, advisory_level } = track.rtt;
 
  const pathColor =
    advisory_level === "ALERT" ? "#ff4d4f" :
    advisory_level === "WATCH" ? "#faad14" :
    corridor_stability > 0.9 ? "#52c41a" :
    "#1890ff";
 
  return {
    pathColor,
    labelBadge: advisory_level,
    ghostPositions: extrapolateGhosts(track)
  };
}

8. 🚀 Path to Phase‑2 and Phase‑3#

9. 🏁 Summary#

Phase‑1 RTT/Inside integration gives ATC and Space Force operators:

  • Predictive clarity
  • Structural coherence
  • Drift‑aware situational awareness
  • Zero‑risk overlays
  • A clear path to deeper integration

It is the fastest, safest, and most impactful way to introduce resonance‑time intelligence into global air and space traffic management.
