Tachbase: Pilot EFB

New in 2.3.2: all-new vector street basemap, airport diagrams right on the map, routes ATC actually assigns & pick-your-layers offline downloads. Improved GDL90 support.

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.

FREE TO START Browse the moving map, FAA charts/plates, and airport pages with live METARs — no account required. With a free account, nothing lives on one device: your logbook, flights, plans, aircraft, and checklists sync across iPhone, iPad, and the web — a lost iPad loses nothing.

MOVING MAP Airports, airspace, navaids, fixes, airways, and military training routes — 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. Add range rings, centerlines, glide ring, and track breadcrumb. Download states & territories offline.

CHARTS & PLATES FAA approach plates, departure/arrival procedures, airport diagrams, and takeoff/alternate minimums with pan/zoom — plus taxi diagrams where the FAA has none. With Pro, plates are georeferenced (your aircraft draws on the chart), drop any chart onto the map, and see NOTAMs for the current plate.

AIRPORTS Frequencies, runway wind analysis, METARs/TAFs, NOTAMs, fuel & services, sunrise/sunset, and the chart supplement — all offline-ready.

WEATHER Decoded METARs and TAFs, 270+ imagery products cached offline, and FIS-B weather with an ADS-B receiver. Pro adds live FAA weather cameras.

TRAFFIC & FLIGHT INSTRUMENTS Connect any GDL90 ADS-B receiver — Stratux, Stratus 3, SkyEcho — for live traffic and weather. A Primary Flight Display 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, and check a vertical 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. Push alerts when your plan is accepted, amended, or closed, or en-route weather crosses your route. Direct-To with holds and track lines.

CHECKLISTS Tap-to-run normal and emergency checklists — start from templates for popular GA aircraft or build your own.

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 ForeFlight-compatible CSV, with 30-day undelete. Sign entries inline or via QR for instructor endorsements.

PLUS: Home Screen widgets (METARs, currency) and a live Lock Screen flight activity; an aircraft hangar with weight & balance and maintenance tracking; an E6B; an offline FAA library (FAR/AIM, handbooks, ACs); your own POHs and PDFs; iCloud backup; contacts; 8 themes.

TIERS Free (account): the Weather tab, sync, the flight-plan builder, Direct-To, and basic logbook and planning. Pro: everything else — georeferenced plates, the PFD, ADS-B traffic/FIS-B, hazard alerts, cameras, checklists, FSS filing, full logbook, the FAA library, and offline maps & charts.

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.
