Tachbase vs Jeb's Horizon EFB

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 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.
