787 trim Percentage

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
