B777 Slats drive and LVO ops

[applecrumble]

Hello,

It says on the B777 not to conduct LVO ops if the Slats Drive message is shown. The same not is not made for Flaps Drive. Anyone know the reason why you could do an LVP approach with Flaps Drive shown but not Slats Drive?

The FCTM says that if leading or trailing edge devices are not in the proper position for F20/25/30 then auto lands are not certified .

So from a basic point of view these configurations have not been extensively tested for auto lands I guess
