9.2 Takeoff Performance

V-Speeds Explained
Before every departure, three critical speeds must be calculated and inserted into the MCDU:
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
VR – Rotation Speed
The speed at which the pilot initiates aircraft rotation
Smooth and controlled pitch input is required
V2 – Takeoff Safety Speed
Minimum safe climb speed after liftoff
Ensures sufficient climb performance in case of engine failure
Operational Importance
Incorrect V-speeds can lead to:
Unsafe takeoff performance
Runway overruns
Insufficient climb capability
Core Rule
“Takeoff performance is calculated – never estimated.”
