Am I right or wrong is not important. What I quoted is from Airbus 17th Performance and operations conference Dubai. Climb gradient varies from when you put the gear up to thrust reduction, after thrust reduction to acceleration point, and where you reach 250 kts. On a graph of altitude vs diastance if you draw lines from origin to these points, there will be three gradients. Average of these gradients is the climb gradient. You can read it for yourself. If you differ from Airbus you can send them a query. This is not same as missed approach gradient. Missed approach gradient is not average gradient but the minimum gradient upto the limiting obstacle, a plane below which it is forbidden to fly. This is also given in a presentation on Go around. I said SID gradient in the original post I stand corrected I am talking about all engine climb gradient.
