Adjusting Your V1 ?
If my Beech 1900 TKOF data card states that for a particular day I can takeoff at a weight of 7000 kg with say a v1/vr of 120 but my actual BRW is 6000 kg and the v1/vr is 100, would it be safer to use the 120 which allows that litle bit longer for the decision to reject the takeoff ?
