Aircraft Perf Calculator

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

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!
