How much trim i should set for 777 300ER during landing i set 30% but it touch down lit bit late nose remain little bit up and also for A380 suggest me trim settings for both big planes
You can find all the landing information here on this topic below. Hope this helps!
Reading their post, it appears that they have seen that topic, hence where the 30% that they wrote came from.
To answer your question, there isn’t a one trim fits all scenario for each aircraft. There are factors such as weight and speed that affect the recommended trim of a plane. For this, I would experiment with different settings to see what works best for you.
Since you said that you tend to land late with 30% trim, it may be too high for you. I’d lower it to 25% to see if that helps; if it is still too much, you can reduce it again. If you’re landing too early, I would then recommend raising it.
I’m with you though, I’m experimenting myself to see what works with me
