Tachbase vs Jeb's 3D Flight Bag

Tachbase is an electronic flight bag (EFB) for general aviation pilots — preflight planning, in-cockpit awareness, and logging in one fast, offline-first app for iPhone, iPad, and the web. TACHBASE ASSISTANT Ask in plain English — "Any NOTAMs at KSFO?", "Cat A minimums for the RNAV 31 at KPAO?", "Am I night current?" — and get answers looked up live, not from memory: weather, PIREPs and winds aloft; runways, crosswinds and Chart Supplement remarks; approach fixes and minimums from the plate; the FAR/AIM and FAA handbooks; and your own logbook, currency and aircraft. Runs on Tachbase's own servers — your questions never go to a third-party AI. Aviation only; sign in for your own records. Advisory, not an official briefing. FREE — EVERYTHING INCLUDED No subscription, nothing to buy. The moving map, charts and georeferenced plates, in-flight tools, and offline downloads all work without an account. Create a free account and nothing lives on one device: your logbook, flights, plans, aircraft, and checklists sync across iPhone, iPad, and the web. MOVING MAP Airports, airspace, navaids, fixes, airways, and MTRs — tap any feature for details. Airport diagrams draw on the map as you zoom in. Overlay VFR/IFR charts, live weather (radar, satellite, winds aloft, PIREPs, AIRMETs/SIGMETs), TFRs, and your route. Download states & territories offline. CHARTS & PLATES FAA approach plates, departure/arrival procedures, airport diagrams, and takeoff/alternate minimums — plus taxi diagrams where the FAA has none. Plates are georeferenced (your aircraft draws on the chart); drop any chart onto the map. AIRPORTS Frequencies, runway wind analysis, METARs/TAFs, NOTAMs, fuel & services, sunrise/sunset, and the chart supplement — all offline-ready. WEATHER Local Weather for your home or nearest airport: conditions, a plain-English TAF outlook and the 7-day forecast. Decoded METARs and TAFs, 270+ imagery products cached offline, FAA weather cameras, and FIS-B with an ADS-B receiver. NWS warnings, forecaster discussions and satellite loops arrive live from Tachbase's own GOES-18 satellite dish. TRAFFIC & FLIGHT INSTRUMENTS Connect any GDL90 ADS-B receiver — Stratux, Stratus 3, SkyEcho — for live traffic and weather. A PFD pairs an AHRS attitude indicator with an HSI that tracks your active leg or Direct-To. A customizable data bar adds terrain, obstacle, and traffic alerts with spoken callouts. FLIGHT PLANNING The route finder suggests routes ATC recently assigned — SIDs and STARs load with published legs on the map. Add approaches and airways; check a terrain profile with recommended MEA. Wind-corrected nav log with fuel planning, weight & balance, and PDF export. File, activate, amend, and close flight plans with Leidos Flight Services and official FAA/FSS briefings. Direct-To with holds and track lines. SMART LOGBOOK Log flights with approaches, passengers, and cost-splitting; auto-log with a GPS track; track FAA currency; and generate experience and 8710 reports. Import from ForeFlight or MyFlightbook, export CSV. Sign entries inline or via QR for instructor endorsements. AI APPS & DEVELOPERS Bring Tachbase into Claude or any MCP app, or build on our API: weather, airports, charts and regs — and, only with your approval, read-only access to your logbook, currency and aircraft. tachbase.com/developers PLUS: Home Screen widgets and a live Lock Screen flight activity; an aircraft hangar with weight & balance, POH takeoff/landing distances, and maintenance tracking; normal and emergency checklists; an E6B; an offline FAA library (FAR/AIM, handbooks, ACs); your own POHs and PDFs; iCloud backup; contacts; 8 themes. Tachbase supplements, not replaces, certified avionics and official sources. All data — aeronautical, weather, own-ship position — is for situational awareness only, not for primary or IFR navigation. Per FAA AC 91-78 and AC 120-76, the pilot in command must verify all information against official sources.

Jeb's Lite is an 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 on the map with altitude, heading, and ground speed. Powered by adsb.fi with OpenSky fallback. • ATC transcription: tune a LiveATC stream and get the controller's calls transcribed in real time on-device with Whisper. Callsigns, frequencies, and flight levels highlighted live. • 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. • 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. Use OpenAI or Anthropic with your own key, or the in-browser Phi-3.5 model that runs on Neural Engine / GPU — no key required, no data leaves your device. • Offline first: navdata cached on first run; 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 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. orchaerospace.com Sentry is a trademark of uAvionix. Stratux is a community project.
