777-300ER flaps configuration

Vref30 speeds per weight (lbs) 775.000___181 kn 750.000___178 kn 700.000___172 kn 650.000___166 kn 600.000___157 kn 550.000___151 kn 500.000___145 kn 450.000___135 kn 400.000___128 kn 350.000___121 kn And from the Vref30 you can get the other speeds: Vref0___Vref30 + 80 kn Vref1___Vref30 + 60 kn Vref5___Vref30 + 40 kn Vref15__Vref30 + 20 kn Vref20__Vref30 + 20 kn Vref25__Vref30 + 10 kn Notice that on approach only the Vref30 speed has a standard additive of 5 kn.

That is a very confusing one,i just need the same one but in KG and not LBS.

[Sturmovik]

You can choose which weight to use in the lists available, you have KG at the 10th position to the left, and Pounds at the 17th position.

I got really confused can some one answer these questions
Aircraft:B777
Weight:250,000
Landing speed:***
Approach speed:***
Lowest speed without flaps:***
Stalling speed:***
Please someone answer those questions.

[Sturmovik]

250000kg = 551156 pounds.
Landing speed with flaps 30°: 157kts.
Approach speed:
No winds: 157kts.
With winds: add to the approach speed half of the wind component.
Lowest speed without flaps: 237kts (with your weight).
Stall speed: I haven´t found that yet.

[Boodz_G]

Alright thank you !

[Boodz_G]

Isn’t the approach speed suppose to be 180-170

[Sturmovik]

Depends with your weight and position in the pattern (I think).

Polls in topics like these are useless.
