Where do they stop.
The question in my head is, if you have the option to pull the C/B, where do the wipers stop. Do they stow as they would when working normally or do they just stop in the middle of the screen? If so, then your are still stuck with the 230 knot limit.
I have always been told that it is not my job to troubleshoot. leave that for the techs on the ground. Only situation where its ok to think out of the box is if you get something critical that is not described in the C/L.
