Load Alleviation System

[mav63]

How does one know if a B737-800 with retrofit winglets has a Load Alleviation system? Is there a C/B or some other method other than digging through APB drawings?

Thanks!!

I know all 737-700 (any line number) with winglets and all 737-800 line number 1 up to 777 with winglets have it.

Take a look at the speed brake lever position light plate. If LAS is installed there is a 50% detent position.
There is an auto stow CB installed on P6-2. In the E&E Compartment SMYD#2 has part number 285A1010-10X, X can be any digit from 1 trough 9.

Found no Autostow C/B, found in WDM that if present, it is P6-2 A-10. Thanks for the clarity.
