Flight performance: prepare takeoff and landing
Required distances depend on the aircraft and flight conditions. FlightDesk connects airport data, wind components and tools for configured profiles.
Pressure altitude, density altitude and wind
The public calculator uses elevation, QNH and temperature to estimate PA and DA, and resolves wind into headwind, tailwind and crosswind. These results prepare a performance calculation: they are not takeoff or landing distances.

The performance calculator requires an account. Verify that the selected profile matches the aircraft and its flight manual data. An available profile does not make a result applicable to every aircraft of the same model.
Open performance calculations — sign-in required- Select the aircraft and mass for the flight phase.
- Check the airport, runway, declared distances, surface conditions and NOTAMs.
- Match QNH, temperature and wind to the flight time.
- Apply the flight manual method, limits and corrections, and appropriate margins.
