Thanx Zeke, but I hope I dont sound to novice - but If the 7000 kg was ASDR limited for example and was at a BRW of 6000 kg with the above V1/VR speeds, I thought I would be buying myself more time to reject a takeoff at the higher V1/VR.
I know I can "successfully" have an RTO at 7000 kg but I am at 6000 kg using 7000 kg speeds. Does that make sense to you ?
Cheers for your help.
