Real-time performance calculations Performance turns your takeoff numbers into an instant read-out. No more paper charts in the cockpit β€” 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 β€” 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 β€” it's a daily reality. Performance gives me an instant, clear picture of my true performance." β€” 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!
