When you look at ZFW, TOW and LW it gives you a value followed by another value with an S at the end. What does that value stands for?





The first value is the estimated ZFW/TOW/LW, the second is the maximum ZFW/TOW/LW.

β€œS” means it’s a structural limit (i.e. in this case the ZFW and LW shows the maximum certified values). β€œL” means the value is limited by max landing weight (in this case, the max TOW value shown is actually less than the certified MTOW, in order to not exceed the Max Landing Weight (MLW) at destination. If you took off any heavier than 158354 kg, you would not burn enough fuel during the flight to be below MLW at destination).

Best regards,
