V1 = Vr, Balanced field???

[Alpine Pilot]

Thank you for the good answer! So Iīm right that it doesnīt make any sense to reduce the V1 on a long runway!

Thatīs interesting with the contaminated runway. But isnīt my acceleration due to the contamination slower i.e. my ASD getīs longer? Or is the drag of the contamination that great that I have a better braking action as on a dry runway?

Thanks!
