I was on a 737 the other day, and the inner port spoiler was lifting up about 6" on climb out. The flaps were still down, and it was almost as if the airflow was getting under it and lifting it up. I'm no expert, but I can't see any reason why you'd want spoilers deploying on takeoff...as someone with a bit of glider experience it just seems all wrong!

Is this normal?

Thanks for clearing that up. Seems odd though...so you've got flaps extended giving more lift, and spoilers deploying reducing lift at the same time

I'm also pretty sure it was only the inboard spoiler...I would have thought if you wanted to induce roll, the further outboard the control surface movement was, the better?
