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

WET runway?

What did the LPC say was limiting you?

The runway was dry and the limiting factor was for obstacles.

Maybe you've got min V1 figures rather than balanced field or a mid range V1 setting.

Tailwind factoring in I think
