Thank you for your feedback.
I get my quote from smartcockpit.com (Boeing presentation by Performance Engineer: Reduced Thrust Operations, page/slide 51).
I thought there will be some changes in aircraft performance if more or less nose up trim is required. So far Sciolistes confirmed trim change (Thanks Sciolistes).
I am wondering if there will be significant change in aircraft performance if significant reduced thrust is used (for example assumed plus derated takeoff thrust) or even just assumed takeoff thrust.
Feedback appreciated.
