Some more facts, maximum structural payload on the 77L is 63,957 kg, and for the 77W is 69,853 kg.
45t of payload on the 77L represents 70% of its maximum payload capacity.
40t of payload on the 77W represents 57% of its maximum payload capacity.
Maximum? Maybe. The 77L figure seems a bit high though. This is what we work with every day. The numbers are approx due to a/c actual weights.
EK 77L max payload approx 45T
EK 77W max payload approx 60T
EK 773 max payload approx 65T
EK 77F max payload approx 105T
As you can see, the 77L easily carries full payload 16:30hrs. You are correct in saying the 77W does not. But a 3 class 360ish config (read 36T) is quite easily covered.
