Were the numbers computer generated?
How does SQ generate weight & balance and takeoff performance data?
In a previous job we calculated all of the performance and weight & balance data. Currently it is done by computer software, offering many options for takeoff thrust, flap settings, runways, and intersection takeoffs. Both pilots individually verify that the numbers were transferred correctly from the printout.
It is still required to accomplish a manual takeoff data worksheet every year in training. Through experience, however, it has been found that the computer generated performance data are far more accurate, and require much less effort in making configuration decisions.
