Houston ARTCC TFMS Viewer

How to Use

1. Open the site in your browser. No server or backend is required.
2. Upload a custom split JSON (optional):
   • Click the "Upload Split" button and select a JSON file with your split definitions.
   • Example split JSON:

     {
       "24": ["24", "92", "63", "25"],
       "34": ["34", "27", "65"],
       "46": ["46", "47", "48", "49", "50"]
     }

   • Each key is a split name; each value is an array of sector names/IDs as defined in your sectors.geojson.
3. Review the summary tables and flights table:
   • Specialty Summary: Shows current and projected (+5, +10, +20 min) aircraft counts by specialty.
   • Split Summary: Shows counts for your custom splits (if uploaded).
   • ZHU Enroute Online: Lists all ZHU enroute controllers online.
   • Airborne Flights: Table of all tracked flights with details.
4. Data auto-refreshes every 60 seconds.
5. If a data fetch error occurs, use the Retry button to reload without losing your custom split or logging state.

What the Tool Does

• Visualizes all airborne flights within or near (50 NM) the ZHU ARTCC boundary using live VATSIM data.
• Assigns each flight to a sector and specialty using Houston ARTCC sector polygons.
• Projects each flight's position +5, +10, and +20 minutes ahead to estimate future specialty and split loads.
• Displays summary tables for specialties and custom splits, plus a detailed flights table and controller list.
• Supports uploading a custom split JSON for split-based summary counts.
• Auto-refreshes data every 60 seconds, with a countdown and last updated timestamp.
• Handles data fetch errors gracefully, preserving your custom split and logging state.

What the Tool Does NOT Do

• Does not provide graphical maps or sector overlays (table-based only).
• Does not persist custom splits or logs after a full browser refresh (session only).
• Does not support editing splits in the UI yet (upload only).
