IFLY INDIGO
What you are asking has so many variables. No manufacturere gives charts for all contigencies.That is why Airbus has software programmes like LPC. PEP, TLO, ADAS etc. where you can put in the factors affecting the performance and you get the answer. Your company ops executives will have entry to Airbus world website. Read 17th Performance and Operations conference Dubai you will get all your answers. I cannot produce it here.All i can say is SID gradient by definition average gradient and with all engines at TOW of 77000 from sea level you will get above 7.5 upto 5000ft.in flex of 40or 50 degrees.
