Yes mutt I mixed up climb with obstacle, i was thinking of it as 2nd segment limited and thought of it as a climb limit which is solely the case for the minimum regulatory climb gradient. When there are obstacles in the 2nd segment requiring a higher gradient it is an obstacle limit.
So I mixed the 2 up.
So what I meant to say is that within the WAT limits the aircraft will always achieve 2,4%.
However I'm not the one stating that the 2,4% regulatory gradient offers a 1,6%
Net flight path. In my view both are completely seperate. One is certifying minimum the other based on the actual performance and weight on the day that considers local obstacles.
