BFSGrad, I couldn't agree more, with one note - we are not talking about slight error, we are talking about taking off from one third of the 3500 m long runway. If I were in tower at that moment, no argument from the cockpit that 1300 m is enough would deter me from me ordering them to backtrack at least 1000 m. FMS calculations or no FMS calculations.
