In the b737 you have a limitation with anti skid inoperative to remove 7950 from the obstacle/field limited weight.
Question: how would you do that with the RTOW chart I posted?
From b737 supplementary procedures (for windshear precautions) "Consider increasing Vr speed to the performance limited gross weight rotation speed, not to exceed actual gross weight Vr+20 knots.
Question 2: how to know my performance limited weight (field/obstacle/climb..)? Can you give me an example with the RTOW I posted?
