If during retraction from F1 to Fup, that single slat panel gets stuck half way and it does give you roll, if you try to recycle to F1 or more (ignoring the QRH instructions), maybe that single slat will extend further with you not being able to retract it, ending up with more roll. So a possibly manageable situation with a roll that could be compensated and followed by a safe landing, could be aggrevated, becoming an uncontrollable roll.
gonso, in no way there's a risk of an uncontrollable roll.
You've forgotten the Flaps 15 takeoff...
As far as the MEL scenario you mention, I think is a little bit farfetched to have a (really) inop LE slat light and get that particular slat stuck on the same day.
Not at all.
That's exactly what they want to protect you from, limiting the speed to 300/.65, since you can't see it.

[QUOTE]I think the INTENT of the QRH is that if roll is encountered, the slat is actually extended and thus the 230 knot limit applies. If there is no roll, it is purely an indication problem, the slat is assumed to be retracted, and the .65/300 limit is applied to limit roll in case of un-commanded extension of the slat that now has no indication system.

Do you realize the contradiction?
In the first part of your sentence, the limit is 230 kts because the slat is actually extended.
In the second part of your sentence, the limit is 300/.65 because the slat has actually extended by itself...
I told you it's not that simple subject, if we dig deep...
