Upliftic is a fast, pilot-friendly calculator for planning and presenting aircraft fuel uplift. Enter your Current Fuel on Board (smart tri-field: total/left/right), set Target Fuel (lbs) and Trip Fuel (lbs), and get the Uplift in litres instantly—plus a clear ReFuelEU policy check using your Taxi fuel and density constant. New in 2.0: Upliftic on Apple Watch, with watch-face complications and iPhone sync. Designed for the flight deck, Upliftic keeps inputs simple, typography large, and actions obvious. Show the uplift to the refueler in a single tap using the full-screen number view. Need rounded options? Use the three +50 L quick tabs to display uplifts rounded up (e.g., 2300 L, 2350 L, 2400 L). If you're not compliant, Upliftic also provides a dedicated "Refuel EU compliant uplift" suggestion you can tap to present full-screen. Capture last-minute instructions in the always-visible WhiteBoard and open it full-screen; the text auto-fits to fill the display and stays fully readable—without scrolling—even at larger accessibility text sizes. Upliftic also includes a Wind Components calculator (crosswind/headwind/tailwind) with a simple runway + wind diagram for quick checks on the go. Everything works offline, with values persisted between sessions. Features • Apple Watch app: Digital Crown entry with ±100/±1000 buttons, uplift and ReFuelEU check, rounded-to-50 L refueller options, full-screen presenter. • Watch complications: current uplift on the watch face, or a shortcut to a new calculation. • Departure ICAO (optional): shows whether ReFuelEU applies at your departure airport, from the European Commission's list built into the app. • Trip fuel ceiling: the highest trip fuel that still complies with ReFuelEU. • Smart inputs: "Current Fuel on Board" total field syncs with left/right tanks; edit any field and the others update. • Faster entry (optional): auto-commit and hide the keyboard after your chosen digit count for Current/Target/Trip Fuel. • Target & Trip Fuel (lbs): straightforward fields with validation; Trip Fuel is optional. • Uplift result (L): instant calculation plus quick projections for Target +100/+200 lbs. • ReFuelEU policy check: banner turns green/red when Trip Fuel is set; blue when Trip Fuel = 0; grey when the departure airport is out of scope. • Refuel EU compliant uplift (when needed): additional rounded-to-50 L suggestion shown when not compliant; tap to present full-screen. • Taxi fuel (custom): set any value (lbs) and optionally override it on the main screen (clearly marked as default vs override). • Density constant (custom): default 0.567; editable and persisted. • +50 L quick tabs: three narrow buttons below the result—rounded up to the nearest 50 L, then +50 L and +100 L. • Full-screen presenter: tap a tab to show a giant litre value; auto-fits and rotates with the device. • WhiteBoard: always-visible note area; open full-screen, auto-fit text (no scrolling), readable at any accessibility text size, landscape-optimized; quick "Clear" control in the section header. • Wind Components Calculator: enter wind direction/speed and runway number or magnetic direction; get crosswind and head/tailwind plus a simple diagram; quick reset for wind-only inputs. • Accessibility & persistence: Dynamic Type support throughout, VoiceOver labels, values remembered after app restarts. • Offline by design: no network required. Why pilots like it • Built for speed and legibility on the ramp. • Clear compliance signal when Trip Fuel is provided—plus a ready-to-show compliant uplift when it isn't. • One-tap big-number display for refuelers. • No clutter: Taxi fuel and density constant you control, with quick overrides when needed. • Quick wind component check without leaving the app. Notes Upliftic is a reference aid, not certified avionics. Always verify your figures and follow your company SOPs and aircraft documentation when planning fuel.
