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! ## Key features - Real-time performance calculations - Adjusted takeoff distance - Corrected climb rate - Runway usage percentage - Density altitude calculation - Comprehensive airfield database - Geolocation and real-time weather ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/aircraft-perf-calculator/id6541753665/reviews.md ### 4/5 — Mon avis *2024-08-14* Il s agit d une version bêta, Un peu d’indulgence me semble être de mise. Quand à conserver les caractéristiques de tel ou tel appareils, la connaissance des performances de l appareil est un préalable indispensable avant tout vol. Amitiés aéronautiques. PC IULM ### 4/5 — Il serait bien de rentrer les valeurs directes des paramètres sans utiliser les - et + *2024-08-06* Tout d’abord merci pour votre investissement. Garder en mémo les caractéristiques de l’appareil utilisé serait un plus. ### 1/5 — Bonne idée, mauvaise conception *2024-07-22* Même si l’idée est bonne, l’ergonomie de l’application est catastrophique, l’application ne respecte pas les guidelines d’intégration sur iOS. Et aucun usage des services météos natifs à iOS n’est fait. De plus, l’app fonctionne comme une page web que l’on peut zoomer n’importe comment. Vu la simplicité de cette application (on parle d’une formule connue avec quelques valeurs en entrée) on pourrait espérer une meilleure attention portée sur l’ergonomie et le respect des normes d’interactions de la plateforme. ### 1/5 — interface désagréable *2024-07-22* bonjour, c’est toujours difficile de poser un commentaire négatif quand on sait la somme de travail derrière. c’est cependant un outil trop précieux pour la sécurité : l’ergonomie n’est pas du tout au rendez vous. il faut que ce soit intuitif et rapide pour séduire. l’interface est totalement inefficace : lourdeur de la saisie par pas + ou - alors qu’une saisie chiffrée serait si rapide. faire « ludique » n’est pas forcément un plus. un appui rapide sur le bouton + a provoqué un zoom écran qui m’a fait cliquer sur une pub pour le concepteur dont j’ai eu le plus grand mal à me débarrasser. je n’ai même pas vérifié si il était possible d’enregistrer des profils (quand on vole sur plusieurs appareils et aérodromes différents ça peut être pratique) = désinstallé dans les 5 min. je reste avec ma vieille fiche sous tableur. désolé ! :-/ ## Frequently asked questions about Aircraft Perf Calculator ### What is Aircraft Perf Calculator?
