BelgianBoy,
Maybe I miss a point, but reading the extract appended, it very much looks to me like the rwy was not really sufficient. It is approximately 2,900 m long & I remember cockpit crews' comments saying that you may reach V1 on a longer distance than calculated.
Following is extract from Luchtzak:
(Simplistic KISS) recalculation:
70.000 Kg Fuel (FOB) (80.98% Max) = Runway Required (No wind, ISA, Dry, Unsloped) 2583 meters
Extra safety margin V1 @ 144 kts = 5.45 seconds ! (404 meters)
80.000 Kg Fuel (FOB) (83.67% Max) = Runway Required (No wind, ISA, Dry, Unsloped) 2669 meters
Extra Satefy margin V1 @ 144 kts = 4.29 seconds ! (318 meters)
Note: aviators don't practice Rejected Takeoff (RTO) situations AFTER V1 (hostile Test Pilot environment). After passing V1 and (for example) a second engine (N-2) on the same side fails, you're going sideways and definitely not up !! Final result (if you're able to maintain N-2 directional control): visiting the runway end and fence, as in this case.
