Sorry but could I ask you how this works.

On page 10 of limitations, the column I am looking at is THRESH speeds and they must be for approach? because they just list weight and 50 and 40 degrees flaps.
So if this is right and useing the top graph (300B)a weight of 240,000 LB is a touch down speed @50 flaps of 146 IAS.

Is that right?
Take off V1 Vr V2 I found on performance2 page 6  :)

thx
