Wet V1 Speeds
Can anyone explain the concept of a wet V1 speed to me - the explanations I have read don't really make sense to me.
Why the reduced screen height (15 ft as opposed to 35 ft with dry TO)? Surely under wet conditions your take-off distance required should increase so whats with the reduced screen height requirement??
From what I understand a wet V1 is not a 'real' decision speed and the dry V1 remains the actual speed at which a decision is made whether to abort or continue a take off. Then why bother with the wet V1??
