V1 ???
Could someone explain why at a given airfield as A/C weight increases V1 increases.
As I understood it with a heavier aircraft it takes longer to accelerate (uses more runway) and then to stop (uses more runway) therefore a lower V1. A light aircraft accelerates quickly (uses less runway) and brakes quicker (uses less runway) Thus a light aircraft could reach a higher speed and still stop on the runway than a heavy one.
Sorry for being thick!!!
