# 9.2 Takeoff Performance

### V-Speeds Explained

Before every departure, three critical speeds must be calculated and inserted into the MCDU:

</div>#### V1 – Decision Speed

- The maximum speed at which a rejected takeoff can be safely initiated
- After passing V1, the takeoff **must be continued**, even in case of failure

</div>#### VR – Rotation Speed

- The speed at which the pilot initiates aircraft rotation
- Smooth and controlled pitch input is required

</div>#### V2 – Takeoff Safety Speed

- Minimum safe climb speed after liftoff
- Ensures sufficient climb performance in case of engine failure

</div>### Operational Importance

Incorrect V-speeds can lead to:

- Unsafe takeoff performance
- Runway overruns
- Insufficient climb capability

**“Takeoff performance is calculated – never estimated.”**
