What do you recommend for flap settings when taking off with the 747-400?
10 or 20, depending on weight

Thx for the advice
20 seems a bit much. @DELLIS41 I would recommend flaps 10
747s do 20 degree take offs
trust me :D
Flaps 10 and rotate at 175, V1 is 165.
165 Seems high,
I do 155
It depends on runway length, I usually do flaps 10 when I’m heavy on a long runway, or light on a short runway. If I’m heavy on a short runway, I’ll go flaps 20 for shorter distance. Keep in mind that your climb gradient is reduced if you use more flaps, so you might want to cut the de-rate and go flaps 10 if you have high obstacles during climb.
I usually do Flaps 5… oh well
If your runway is short 20 if you’re heavy 20 if runway is long 10 if you are light 10 if you’re empty 5
