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.
Here a quote from another forum
Quote: "AeroTech - performance charts don't give different stab trim settings for derated vs. max power".
A response from another member from the same forum: " I'm afraid they can. Looking at my 737 Perf Inflight. I have separate trim tables for 27K, 26K and 24K, each showing a different trim value for the same weight and MAC
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.
