Multi-tab EFB and pilot utilities

NavLog, flight calculators, weather, and weight & balance in one offline-first app. The same tabbed layout runs in the browser, a Wails desktop shell, and a Capacitor Android build. Built by an FAA student pilot (129.2+ hours, as shown in the live app). A training and preflight reference — verify every number against the POH and the Pilot in Command.

If the demo is useful on a desk or a kneeboard, star the repo.

What it covers

Planning math and saved logs run locally. Live METAR decode needs a network connection to aviationweather.gov. Garmin / ForeFlight .fpl export is included from the briefing flow.

1. 📡 Weather ribbon

• METAR decode from aviationweather.gov, including training fields such as KF45, KDJT, KIMM, KOBE, KMIA, and KFXE.
• Flight category colors: VFR, MVFR, IFR, and LIFR.
• Station strip: Zulu and local time, wind, temperature, altimeter, and the raw METAR, with one-click station changes.

2. 🧮 Flight computer

• Wind triangle: true heading, groundspeed, and wind correction angle.
• True airspeed from indicated airspeed, pressure altitude, and outside air temperature.
• Time–speed–distance for leg time and remaining distance.
• Fuel: gallons per hour, endurance, and 100LL weight.
• Crosswind and headwind components, with a crosswind-limit warning.

3. ⚖️ Weight & balance

• C172 envelope for normal category (up to 2,550 lb) and utility category (up to 2,200 lb).
• CG through the flight: ramp, takeoff, and landing as fuel burns.
• Out-of-limits alert when weight or moment leaves the envelope used by the profile.

4. 🗺️ NavLog and briefing

• Navigation log with course, altitude, wind, TAS, headings, distance, groundspeed, time, and VOR fields.
• .fpl export in the Garmin / ForeFlight XML shape for import into those apps or compatible avionics.
• Printable briefing for the flight log and weight & balance.

5. 📒 Logbook and aircraft profiles

• Local logbook (IndexedDB) for total time, PIC, cross-country, day and night landings, and dual received.
• Aircraft profiles such as C172, PA-28, and DA40, with basic empty weight and station arms.
