I remember in a bizjet sim we took performance manual numbers and ran a high speed abort based on Esssendon runway 17. We picked the weights and temps that would have us right on a balanced field length. With the knowledge of what was coming, we aborted fractionally before V1 and we pulled up right at the end. Jut as the book predicted. But of course we knew it was coming and were all prepared. If it takes you by surprise, well one has to hope training overtakes and you react accordingly, otherwise you're parking in Niddrie and retiring to a small farm on the NSW coast.
