Sky Family - Pilot Assistant is an offline-first supplemental situational display for pilots, student pilots and ground training. Using the phone's motion sensors, compass and foreground GNSS, it provides an original touch PFD, a camera HUD, offline route planning, a pilot toolbox, custom checklists, a personal logbook and a one-tap emergency record. MAIN DISPLAYS • Touch PFD: roll/pitch trend, GNSS ground speed, WGS-84 GNSS altitude, true track or magnetic heading, adaptive portrait/landscape layouts. • Camera HUD: the camera runs only on the HUD page for live preview — no photos, no recording, no upload. • Data-quality gating: mocked, stale or low-accuracy fixes never enter the navigation displays. ROUTES AND MAPS • Offline MAP/FPL: route creation, waypoint ordering, active leg, distance, true bearing, ETE, OBS, and GeoJSON/GPX/KML import. • After separate map-privacy consent, AMap capability and official offline city packages are available in mainland China. Elsewhere, the app uses a configured and available map provider. Routes, waypoints, OBS and position overlays remain usable when no base map is configured or available. • Within a valid offline entitlement, route planning works without a base map, including in airplane mode. PILOT TOOLS (all computed offline on the device) • Wind triangle, runway wind components, pressure/density altitude, fuel endurance and range. • Descent planning (TOD): distance to start descent, required vertical speed, time and gradient. • Holding-entry advice using the AIM/ICAO 70° sectors (direct / parallel / teardrop). • Standard-rate turn bank and radius; still-air glide range. • Sunrise, sunset and civil twilight with one-tap use of the current GNSS fix, in UTC and device-local time. • Two-way unit converter: kt/km/h, ft/m, NM/km, °C/°F, hPa/inHg, kg/lb, L/US gal. • UTC/leg timer, custom checklists and a local personal logbook. ACCOUNTS AND SUBSCRIPTION • PFD, HUD, pilot tools and emergency records work for guests without sign-in. • MAP/FPL routes and waypoints require an account; new accounts receive one free 72-hour trial. • After the trial, users may choose an auto-renewing monthly plan, a one-month non-renewing plan, or a one-year non-renewing plan. The final price is shown by the App Store purchase sheet. • The monthly auto-renewing plan continues until canceled in App Store subscription management; cancel at least 24 hours before the current period ends. Manual plans expire without another charge. • Accounts can be deleted inside the app. • Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ EMERGENCY CONTROL • Saves account, UTC, position and accuracy locally first; when signed in it syncs to Sky Family operations, retrying after connectivity returns. • Important: backend receipt does not mean public search and rescue, ATC or any authority has been notified. IMPORTANT SAFETY NOTICE This app is not certified airworthy equipment and is not an approved navigation source. It does not replace required aircraft equipment, approved navigation data, current charts, NOTAMs, weather or rescue services, and must not be used for primary navigation. GS is GNSS ground speed, not airspeed; ALT is WGS-84 GNSS altitude, not barometric altitude. All calculators are planning and training aids only — fly by the aircraft manual, published procedures and ATC.
