I do know the 787 has a nose dive attitude when a low trim
Hey Frank!
Trim usage is dependent on a few factors, such as aircraft load and weather.
Assuming the weather is decent and your aircraft load is similar to any of the following percentages, this chart gives a relatively accurate outline for the 787-8s suggested trim.
| Load % | Takeoff Power Setting | Takeoff Flaps | Trim | Rotate |
|---|---|---|---|---|
| 25% | 75% = 94% N1 | Flaps 5 | 0% | 140kts |
| 50% | 75% = 94% N1 | Flaps 5 | 0% | 150kts |
| 75% | 77% = 95% N1 | Flaps 5 | 10% | 160kts |
| >75%*** | 80% = 98% N1 | Flaps 5 | 10% | 165kts |

I’ll drop a personal opinion in here!
For the B787, I’ll use 20-25% for Takeoff, and around 30-40% landing. In the air, I’ll switch it around depending on how the plane is doing, but it’ll hover from 0-10%.
Rember that these are just personal opinions on how I like my trim on the B787.
Hope this helps!!
