What do you mean by full? It would get absolutely nowhere near MTOW out of JNB at any time of year. Nowhere close!
Full cabin. A butt in every seat and their bags on the aircraft.
Not consistently. No cargo is going at times and just a question of how else you have to leave behind. 30C degree takeoff temperature at 5700ft AMSL, would mean about a 30t hit. 15C degree takeoff temperature about a 20t hit. So it's easy to see how the summer temperatures at JNB affect performance on the B77L. If you're also carrying extra fuel due to winds, then you're hitting too big of a penalty and rather carrying a bigger revenue payload and stoping for fuel.
