Aircraft Perf Calculator vs WingLog ULM

Real-time performance calculations Performance turns your takeoff numbers into an instant read-out. No more paper charts in the cockpit — enter your manufacturer data and the app does the rest. KEY FEATURES Adjusted takeoff distance Computed automatically for the current altitude and temperature Corrected climb rate The real-world impact of density altitude on your performance Runway usage The percentage of runway required, shown at a glance Density altitude Automatic standard ISA calculation Comprehensive database Over 29,000 airfields (ICAO codes and names) Geolocation Airfields within a 100 NM radius Calculations at your current position Real-time GPS altitude and temperature Automatic/Assisted Selection of Runways based on the wind length of the runway, pilots can select graphically the appropriate runway as well. display of TODA, TORA,etc.. Built-in weather Temperature and elevation estimated automatically via Open-Meteo Visual alerts Color-coded for normal, good, degraded, or poor conditions TRUSTED BY OVER 6,000 PILOTS Co-developed with Xavier ULLIANA — microlight instructor and mountain pilot, and a member of France's national Mountain Flying division. "In the mountains and on the flatlands alike, density altitude isn't a theoretical notion — it's a daily reality. Performance gives me an instant, clear picture of my true performance." — Xavier ULLIANA, Microlight Instructor Algorithm based on the Koch curve, with validated correction factors. PRACTICAL AND RELIABLE Works offline Automatically saves your settings Favorites list for the airfields you fly most Available in French and English Real-time calculations IMPORTANT Performance is a decision-support tool. The pilot in command remains responsible for: Verifying all calculations The final assessment of flight conditions The final decision to take off Compliance with their aircraft's flight manual Factors such as crosswind, runway slope, and surface condition remain for the pilot to assess. Always verify against your flight manual. Safe flights!

WingLog is the flight companion designed for ultralight, microlight and light-sport pilots (ULM / VDS / LSA) — not a stripped-down version of a heavy IFR app, but a focused tool for how we actually fly VFR. GO / NO-GO IN PLAIN LANGUAGE Set your personal minima once. WingLog reads the latest METAR, TAF and SIGMET for your field (or the nearest station) and gives you a clear Green / Caution / Red verdict, explained in plain language — wind, crosswind, visibility, ceiling, weather, data age. It is the decision you make every morning, made faster. AUTOMATIC LOGBOOK Start tracking and fly. WingLog detects take-off and landing from GPS, identifies the airfields, and fills in route, duration, distance and the GPS track. Confirm with a tap. Your logbook stays private and syncs across your devices via iCloud. AIRFIELDS, AIRSPACE & WEATHER Browse a worldwide airfields database with runways, radio frequencies, sunrise/sunset, and the nearest weather — plus OpenAIP airspaces, navaids and VFR reporting points on an aeronautical map. Add the small UL strips that no one else maps, and share reviews and photos with the community. FLIGHT COMPUTER (E6B) Crosswind and headwind components, density altitude, top-of-descent and unit conversions — the calculations you actually use, offline. AIRCRAFT & MAINTENANCE Track engine hours (updated automatically from your flights), annual inspections and revision deadlines, with proactive reminders. Share an aircraft with co-owners: hours and flights stay in sync for everyone. ON YOUR LOCK SCREEN A Go/No-Go widget on your Lock Screen, and a Live Activity that keeps your flight timer and altitude in view while you fly. Ask Siri "Can I fly?". 3D FLIGHT REPLAY Relive any flight in 3D, with the track coloured by altitude over the real terrain you flew. METRIC OR US UNITS Visibility in metres or statute miles, pressure in hPa or inHg, temperature in °C or °F. FREE, FOR REAL Go/No-Go, the automatic logbook, GPS tracking, one aircraft and airfield browsing & contribution are free, forever. WingLog Pro unlocks the rest: PDF/CSV logbook export, advanced statistics & currency, 3D replay, unlimited aircraft, full maintenance with notifications, and aircraft sharing. Pro is an auto-renewing subscription (yearly or monthly) and starts with a 1-week free trial. — SAFETY — WingLog is a decision-support and record-keeping tool. Weather, airspace and airfield data come from third-party sources and may be incomplete or delayed. WingLog does not replace the official pre-flight briefing, NOTAMs or current aeronautical charts. The final decision always rests with the Pilot in Command. Languages: English, Italiano, Español, Français, Deutsch. Fly safe — and remember, the final decision is always yours as PIC Subscription automatically renews unless cancelled at least 24 hours before the end of the current period.
