I have been experimenting with the 787-9 for the last 40 hours or so, and think that I have determined various aircraft speeds for take off and landings. I have been using the MLW (Max. Landing Weight) as my foundation. I am curious if anybody has posted the numbers for the 789. I’m not looking for cruising numbers. Below I will include the numbers that I have found:
Weight of Aircraft: - 192,767 kgs.
**Takeoff Power Setting ** - 80% = 98% N1
Flaps - 15˚
Rotate Speed 120kts - 125kts
Use flaps as necessary based on aircraft speed.
Established on final with gear down, flaps 30 -150kts - 155kts when the winds are not gusting. 155kts -160 kts when winds are gusting.
These are some of the numbers that I eventually came up with, based on the aircraft weight as mentioned above. Let me know what your thoughts are, and if you have any other performance numbers to contribute. Hope this helps!
