Also, on aircraft that use AT derates, fixed derates and improved climb, depending on the runway/flap/environment the AEO climb out pitch is spread over quite a wide band. As above, on the 777 we go towards 15degs with emphasis on towards while picking up speed trends and/or flight director commands during the latter part of the rotation. Fully derated on a long runway near sea level, 10degs is more like it but full-power off something short is nearer 20degs, possibly above.
