We also correct for WAI and EAI for takeoff performance calculations:
250 kg for EAI, 1350 kg for WAI and EAI together.
The reason for the correction on WAI is not clear to me. Either Boeing thinks the trip off mechanism might fail or they think we are fast enough to switch the system back on again after liftoff but before 35 feet, since this is the end of the takeoff for performance calculations.
I'm gonna practice on the last possibility
