Tachbase: Pilot EFB
Charts, ADS-B, planning & logs
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New in 2.3: aircraft checklists, Home Screen widgets & flight-plan push alerts. Moving map, georeferenced FAA charts, ADS-B traffic & weather, logbook. Free to start.
Tachbase is an electronic flight bag (EFB) for general aviation pilots — preflight planning, in-cockpit awareness, and logging in one fast, offline-first iPhone and iPad app, with a companion web app.
FREE TO START
Browse the moving map, FAA charts/plates, and airport pages with live METARs — no account required. Create a free account to sync your logbook, aircraft, and flight plans across devices and the web.
MOVING MAP
Airports, airspace, navaids, fixes, airways, and military training routes — tap any feature for details. Overlay VFR/IFR charts, live weather (radar, satellite, winds aloft, PIREPs, AIRMETs/SIGMETs), TFRs, and your route. Add range rings, centerlines, a power-off glide ring, and a track breadcrumb. Download states & territories for offline use.
CHARTS & PLATES
FAA approach plates, departure/arrival procedures, airport diagrams, and takeoff/alternate minimums with pan/zoom — plus synthetic 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 the NOTAMs for the current plate.
AIRPORTS
Frequencies, runway wind analysis, METARs/TAFs, NOTAMs, fuel and 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 FAA weather cameras — tap a site for near-real-time views.
TRAFFIC & FLIGHT INSTRUMENTS
Connect a Stratus / GDL90 ADS-B receiver 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
Build routes with a route finder; add SIDs/STARs, 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 IFR/VFR flight plans with Leidos Flight Services and pull an official FAA/FSS briefing. Push notifications when your plan is accepted, amended, or closed — and when en-route weather crosses your route. Direct-To guidance with holds and track lines.
CHECKLISTS
Tap-to-run normal and emergency checklists, synced across devices — start from templates for popular GA aircraft or build your own.
SMART LOGBOOK
Log flights with approaches, passengers, and cost-splitting; auto-log flights with a recorded 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; a 17-function E6B; an offline FAA library (FAR/AIM, handbooks, ACs); your own POHs and PDFs; iCloud backup; contacts; and 8 themes.
TIERS
Free (account): the Weather tab, cross-device 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 with push alerts, full logbook, the FAA library, and offline maps and 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.

Ratings & Reviews
NEW IN 2.3
• Checklists (Pro) — tap-to-run normal & emergency checklists, synced across your devices. Start from included templates for popular GA aircraft (172, 182, Archer, SR20/22, Bonanza, DA40, and more) or build your own.
• Home Screen widgets — METARs for your airports and your flight currency, in three sizes.
• Live Activity — an in-flight Lock Screen card with leg, distance, groundspeed, and ETE/ETA. In the Dynamic Island, your next waypoint and distance are a glance away.
• Flight-plan push notifications (Pro) — know the moment Flight Services accepts, amends, cancels, or closes your plan, assigns a squawk or expected route — and when new en-route weather crosses your filed route.
• En Route Alerts — see what Flight Services flagged along your route, with severity, right on the flight plan page.
• Flight tracking controls — Start/Pause/Stop your tracking session from the flight tools menu; auto-start is smarter about ignoring the drive to the airport.
• Own-ship, your way — choose your aircraft symbol and its color (and a color for ADS-B traffic) in the new Appearance settings. The map and georeferenced plates follow along.
• Offline for the islands — download charts and maps for Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Marianas, American Samoa, Midway, and Wake.
• New app icon.
ALSO IMPROVED
• Terrain alerts now warn about real ridges near airports instead of going quiet in the terminal area.
• Direct-To works like your panel GPS — reopening D→ preloads the active waypoint, so redrawing the course from present position is two taps.
• With the PFD docked, traffic alerts stay clear of the attitude indicator, and centering the map accounts for the panel.
• The flight plan panel fits one screen on iPhone — terrain profile, route, and Send to Plans, no scrolling.
• Chart editions now switch over automatically on their FAA effective date — even offline. Download the next cycle ahead of time and the changeover is instant, with nothing to re-download; old editions clean up after themselves.
• The offline storage readout shows the true size of your downloads, and offline chart packs no longer re-download when they're already current.
• The Wind Flow overlay stays smooth at every zoom level.
• Charts you've viewed re-open offline, and the power-off glide ring now works offline too.
• Old FIS-B radar and weather graphics expire instead of lingering after a flight.
• Sharper FSS status: no more false "route changed" differences, and a clearer Amend/Refresh flow.
• Fixes: iPad Weather crash, blank Flight Tools screen on iPhone, Route Finder tab display, and more.
