The issue is not SOP or what whoever will do, it is about available
distance to stop if an abort takes place at speed that is above V1
AT 54000 KG??
IF AT 64000 KG , LESS RUNWAY AND 30 KTS MORE SPEED AND STILL
ON PAPER THEIR IS ENOUGH RUNWAY TO STOP THEN at 54000kg
I should be able also to stop at 149 kts safely.
