3D EFB — map, weather, ADS-B, live ATC, flight planning.
Jeb's Lite is a free electronic flight bag (EFB) for general aviation pilots — moving map, charts, weather, traffic, and ATC transcription, all in your pocket. It's the lighter, app-store edition of Jeb's Flight Bag from Orchestr Aerospace. WHAT'S INSIDE • Moving map with VFR sectional, IFR enroute (low/high), satellite, and terrain layers. Your ownship icon updates live from GPS as you fly. • Live weather: current METAR and TAF for any airport, NEXRAD radar overlay, winds aloft. Data sourced from aviationweather.gov. • ADS-B traffic: nearby aircraft rendered on the map with altitude, heading, and ground speed. Powered by adsb.fi with OpenSky fallback. • ATC transcription: tune a LiveATC stream, get the controller's calls transcribed in real time on-device with Whisper. Callsigns, frequencies, and flight levels highlighted as the audio comes in. • Flight planning: type a route ("KOWD KBOS"), get distance, ETE, fuel burn, and a vertical profile. Airports, navaids, fixes, and airways all queryable. • Airport reference: runway diagrams, frequencies, fuel availability, and FAA approach plates for the US (free worldwide chart sources where available). • AI copilot: ask "should I fly given the current METAR for KBOS?" or "decode this TAF" and the on-device AI answers using the live data you've already fetched. Bring your own OpenAI or Anthropic key, or use the in-browser Phi-3.5 model that runs on WebGPU — no key required, no data leaves your device. • Offline first: navdata cached on first run; the moving map keeps working in the air with no signal. WHO IT'S FOR VFR and IFR private pilots, student pilots, CFIs, and anyone planning a flight from home before driving to the airport. JEB'S LITE vs JEB'S FLIGHT BAG (FULL) Lite is the mobile + web experience. The full Jeb's Flight Bag prosumer edition adds hardware integrations — USB SDR (bring your own ADS-B-in receiver), GDL90 input from a Sentry or Stratux, native PDF rendering for terminal procedure publications, and runs on Jetson Orin Nano or Raspberry Pi 5 cockpit hardware. Lite has the same software, minus the hardware bridges. SAFETY Jeb's Lite is advisory only. It does not replace official charts, the weather briefing, ATIS, the POH, or any FAA/Transport Canada/EASA publication. The pilot in command is always responsible for the safe conduct of the flight. Cross-check every value the app shows. ABOUT Built by Orchestr Aerospace Inc., based in Montréal and Irvine.
