## What is 天空之家?

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.

## Version history (last 3 releases)

### 1.2.3 — 2026-09-03

Adds an on-device barometric channel with QNH correction for standard pressure altitude, unpressurized installations, and cabin pressure altitude in pressurized aircraft. Devices without a pressure sensor now hide these items and explain availability in diagnostics. Emergency records now require confirmation and provide a 10-second undo window, with clearer notice that the feature does not contact ATC, police, medical, or rescue services. Improves Dynamic Island, notch, portrait safe-area layouts, and consistent three-dimensional tool buttons. Retains global metric/imperial, Celsius/Fahrenheit, and 90°/180° mounting modes.

### 1.2.1 — 2026-09-01

Redesigned the app with a cockpit-inspired metal instrument style. The PFD now places attitude, heading, ground speed, altitude and vertical speed in individual recessed instrument bays. Refined gradients improve the sky and ground layers, while consistent semantic colors make aircraft, speed, altitude and vertical-speed indications easier to read. Bottom navigation now uses full-button backlighting, and settings, speed-band inputs and action buttons share tactile three-dimensional controls. Safe-area handling has also been improved for notches, rounded screens, portrait and landscape layouts. Real-time telemetry auto-start, 90°/180° mounting modes, global metric/imperial units and Celsius/Fahrenheit remain available.

### 1.2.0 — 2026-08-25

No release notes.
