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.

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!

English
• Works offline — the full calculator, Köch chart, and 29,000-airfield
search now run with no connection.
• QNH correction — enter the altimeter setting to compute takeoff and climb
against true pressure altitude, not raw field elevation.
• Field elevation, temperature, and QNH auto-fill from weather on airfield
or GPS selection (editable).
• The app now updates itself automatically when a connection is available.
• Refreshed in-app help.
