Jeb's Horizon EFB

Jeb's Flight Bag is a next-generation Electronic Flight Bag built for pilots who want a serious cockpit toolkit without the lock-in of subscription-only iPad apps.

WHAT YOU GET
– Moving map with FAA VFR Sectional, IFR Low, IFR High, satellite, and dark-mode tile layers.
– Live ADS-B traffic via Sentry, Stratux, Stratus, Garmin GDL, uAvionix SkyEcho — anything that broadcasts GDL90 over WiFi.
– Real WAAS GPS from your portable receiver — even on a WiFi-only iPad with no internal GPS chip.
– NEXRAD weather radar over the US (Iowa State Mesonet, sub-km, ~2 min refresh) and RainViewer worldwide composite outside CONUS.
– FAA d-TPP approach plates with georeferenced ownship overlay — the aircraft chevron moves on the plate at the right pixel position as you fly.
– METAR / TAF / NOTAMs / SIGMETs / PIREPs / TFRs / winds aloft, with color-coded VFR / MVFR / IFR / LIFR flight category dots at every airport on the map.
– Two-finger touch ruler — measure nm + bearing between any two points.
– Synthetic-vision PFD-style attitude indicator from your device's IMU. The rotation-vector sensor is fused even on tablets without a gyroscope.
– ATC frequency reference, nearest airports / navaids / fixes, ICAO route export, auto-routing with SID/STAR insertion.
– Pilot's Operating Handbook reference — Cessna 152, 172, 182, Piper PA-28, Cirrus SR22, plus PDF upload that uses Claude AI to extract V-speeds, weights, fuel, and performance numbers from any aircraft's POH.
– Performance calculator: density altitude, takeoff / landing distance with weight, headwind, and POH baseline corrections.
– On-device LLM copilot — answers flight-planning questions, decodes METAR-ese, walks emergency checklists. Routes to Anthropic's Claude API when an API key is configured, falls back to bundled MLC LLM locally on capable hardware.

WHO IT'S FOR
– Student pilots who want a capable EFB without a big yearly bill.
– International pilots flying outside FAA territory — the moving map and radar are worldwide; everything else gracefully falls back to the relevant regional AIP via browser deep-link.
– AI-curious aviators who want a copilot in the cockpit without sending their flight data to a corporate server.

WHAT YOU NEED TO KNOW
– Coverage today is North America (United States + Canada). Airports, navaids, fixes, airways, approach plates, and ADS-B fallback are sourced from FAA / Nav Canada data. The moving map renders worldwide via OpenStreetMap tiles, but other layers are best-effort outside North America.
– This app is provided for situational awareness ONLY. It is NOT a primary navigation source and NOT a substitute for current sectionals, plates, or certified onboard avionics. Read the in-app liability disclaimer before flight.
– Sentry, Stratus, Stratux, Garmin GDL, and SkyEcho are trademarks of their respective owners. Orchestr Aerospace Inc. is not affiliated with any receiver manufacturer.
– Optional Claude API key (from console.anthropic.com) unlocks AI POH parsing and the on-device copilot. Without a key, regex-based POH import + offline copilot still work.

NOT FOR
– Use as a sole means of compliance with FAA, EASA, Transport Canada, or other regulatory navigation requirements.
– Replacement of certified onboard avionics or current published charts.
– Operations where loss of the EFB would create a safety hazard.
