Kay Pam,
Thanks for your efforts, much obliged. Not to worry about the 1430m runway length, the "test" is a situation where runway available equals accelerate-stop distance of the plane in question. Your numbers would be correct for a mid-weight Global Express business jet, perhaps V1 being a bit high, but in the right area for that 1430m ASDA.
