  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

  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!
