Flight Tracker Skill
No API key or setup required — works out of the box.
Commands
Track an aircraft by callsign
flight-tracker aircraft EK203
flight-tracker aircraft QR42 --format json
flight-tracker aircraft BAW117 --format summary
Shows live position, altitude, speed, heading, and vertical rate for a single aircraft. The aircraft must be currently airborne.
Callsign format: Always uppercase. OpenSky uses radio callsigns which usually match the ICAO airline prefix + flight number (e.g. EK203, QR42, BAW117). Note that the radio callsign may differ from the ticket flight number — for example, British Airways flight BA117 uses callsign BAW117.
Aircraft overhead a location
flight-tracker overhead --lat 25.2048 --lon 55.3657
flight-tracker overhead --lat 51.4775 --lon -0.4614 --radius 100
flight-tracker overhead --lat 40.6413 --lon -73.7781 --format json
Shows all airborne aircraft within a radius (default 50 km) of the given coordinates. Results sorted by altitude descending.
Rate Limits
The OpenSky free tier allows one request every 10 seconds. The CLI handles rate limiting automatically with exponential backoff retries (configurable via --retries).
Output Format
All commands default to --format summary which prints a human-readable table. Use --format json when piping output to another tool or agent — this outputs clean JSON to stdout with no extra decoration.
Global Options
--retries N — Number of retries on failure (default: 3)--timeout N — Request timeout in seconds (default: 20)
