Why such a low V1 Figure?
Afternoon,
In our airline we use the Airbus latop takeoff performance and the other day I was calculating figures usiing GLA RWY23.
The V Speeds that came out were V1 127, VR 146 and V2 149.
Can anyone explain why I have such a low V1 figure as I couldn't explain it to the operating Captain.
Thanks
